yeah winner! I didn't have time to do all the calculation but I remember from a physic class a few years ago that one of the big "practical" issue is the release of the pendulum. You don't want to get any lateral movement when you launch it. That's why a lot of people use the burning wire trick you used.
Look at the equation near 3'40''. Instead of 24 h (=86400 s, sun day) you should use 86164 s (stellar day), then your results will be even more accurate. Congrats anyway.
Yute Yes, and NASA is hiding "da truth". Millions of physicists, engineers, pilots, cartographers, oceonographers, etc, along with tons of soldiers that are patrolling around Antartica, and NOT ONE of them speaks out accidentaly or on purpose....Please, go back into the cave/basement you crawled out from.
Yute Option 1 (reality) is that Earth is a rotating sphere. This experiment is consistent with that idea and proposing that you don't notice a 0.2% weight difference when travelling from a pole to the equator seems reasonable (haven't actually checked the math but let's take a huge leap and assume you did it correctly). Everything you can observe is consistent with a rotation spherical Earth. Option 2 (your proposition) is that a massive magnetic field rotates somewhere beneath or above the flat Earth to make the pendulum move and for some reason isn't detected and doesn't interact with other metals in the same way and rotates the other way south of the equator. On top of that you propose that you would notice a weight difference that is equivalent of eating an egg. You honestly think option 2 is reasonable?

One small issue with making the pendulum too long is that you need a heavier and heavier bob. If you need a good string for it, they sell it at Mountain Equipment CO-OP. I've also heard good things about high tension fishing line as well.

One thing that is also really neat about this is how amazingly accurate this was, I did the math myself and nothing was off by more than 4%. Here's the numbers I got for anyone who's curious: The predicted pendulum drift for that latitude was 7.75° with the observed pendulum drift being 7.89° with an accuracy of 98.2%, the latitude prediction accuracy was to around 99.6% and the north pole distance prediction accuracy was up around 96.4%.
@feathered3167 Did you also calculate the movement from the earth rotating the sun at 66,000mph? Or the Earths Movement following the Sun at 55,000mph? Think of the forces applied on that pendulum with is Spinning at 800mph while going another direction at 66,000mph then travelling in a straight line at 66,000mph.
To flat Earthers - please don't just state that "the Earth is flat" or something similar. It would be helpful if you explained exactly what you feel is incorrect about the experiment. Note that the measured value is pretty close to the theoretical (based on a globe model) value. Is that just a coincidence?
the problem is assuming a globe model in the first place. If we have numbers for an assumed size of a ball then of course this math will work out. Why did you have to manually start the pendulum in the first place. Wouldn't the force of the rotation of the earth cause the pendulum to perform its movement.
What if the limitations of your vision system was explained to you as 'curve of the earth'? And this was was told you since you went to school.

Flatards complain that Foucault's pendulum is artificially made rotate in the museums by having it powered, they are just powered to avoid them from stopping.\ Well, here it is, a non-powered pendulum showing Earth's rotation.
While this was a great experiment, you have to be kidding yourself if you think it was not "powered". Even if the string was loose, which it wasn't,. This sets it off to the velocity formula. I bet you can calculate how long it would take before that mass comes to rest. Sorry, but this is not motion by spinning of the earth, and I think the person doing the video is not claiming such, as he knows it is not happening. You also have to look into Jefemenko's field theory explanations, and this fall along. As we also have to factor in true north azimuth magnetic north. SO these things are NOT very scientific FROM THE GET GO! We have MUCH better tools today. Why not use these tools vs the 200 year or 2000(Eratosthenes) year old methods? Mind boggling!! Takes a bit more money, but much less setup and time, with NO variables that start from a WRONG tangent. Now I think doing the test IS very praise worthy, and encouraging to know. But the conclusions we draw from these are very dangerous. We feed our ego, and our false sense of understanding in a dogmatic manner. This needs to stop.
@Alan J try chewing in sections, and you might understand it. Be warned, each bite is a lot to chew. If you can follow all of it, then just adhere to the conclusion. Size is not a factor in this.
@Yute firstly aeroplanes would be slightly affected by this phenomena, it would just be so small. Comparable to a minor breeze which they would constantly be manually and/or automatically correcting for anyway. So whether or not this force is actually effecting the plane doesn't make a difference because it would be indistinguishable from other factors affecting the plane. And really? You're seriously going to sit there and claim earths magnetic field is causing this. You think the force applied to the pendulum would just so happen to be perfect in which it produces a deviation in the swing of the pendulum which near perfectly matches the exact deviation in the pendulums swing we would expect to see if it is at that exact latitude on a spherical rotating earth. Which then allows him to almost perfectly predict his latitude. NO. The chances of this perfectly matching up would be near zero. The magnetic field strength of earth at this position, the magnetic field strength of the pendulum, the magnetic flux passing through the pendulum, Magnetic reluctance of the pendulum, the amount of energy lost as heat through magnetic induction and many many more factors would all have to perfectly sum to just coincidentally produce a force which we would expect to see on the pendulum if the earth was spherical and rotating at the rate it is at that position. Yeah no, not gonna happen. If you're so confident magnetic fields are producing this effect perfectly to match which predictions of the globe earth you should be able to explain and calculate how. If you are going to reply to this I better see some electromagnetism principles and calculations to show these results can be produced and based off values such as the ones I listed earlier will produce the exact results in this experiment otherwise everything you are saying is no more than stupid claim to make the flat earth idea seem worthy. And lets just for this situation assume you are correct about the increase in the speed of individuals on earth because you clearly have no knowledge of the principles of relative motion, but let's just assume you are correct. Firstly we do not feel velocity we feel acceleration. So based on the acceleration of 2.15 cm/s/s, that is 0.0215 m/s/s, an acceleration like that would equivalent of accelerating roughly from 0 to 28 m/s or 0 to 100km/h in just under 22 minutes. That shit is nothing, you would feel more force if a bug flew into your face. What I am saying is it is not noticeable. Remember if you're going to reply don't forget those calculations and more detailed explanations with actual supporting data.
Don't forget that Canada stretches from 41 degrees north to 83 degrees north. So it's hard to understand how you could live further north. There's a lot of "north" to Canada.
@@gustavgnoettgen When you're stuck out into the Atlantic like a thumb, it is pretty obvious. Even 50km inland the climate is very different then along the coast.
What I liked about this video is that you can see the pendulum without the magnets around ( that people may have suspicions that are manipulating the pendulum ) and the extraction of latitude from really measuring it!
The period T for a pendulum is NEARLY independent of amplitude, especially when θ is less than about 15º. For a large amplitude, T = 2π square root of √L/g is less correct, and the exact equation gets complicated. So there are reasons for the small error in the video.
Also it wasn't a dumb question, we weren't sure if the high tension string we used was thin enough to avoid slowing the pendulum due to air friction. Turns out it worked really well. :)
I'm curious if you could explain how this experiment follows the scientific method. And what your independent/dependant variables were, as well as your controls. How did you control for magnetic interference? I'm honestly curious because I am using your video for evidence of rotation against a flat earth believer and I want to come correct. Thanks a bunch and great work!!
@Zakir Khan I'm interested in how you came to that conclusion. The bob was made of lead. Which is not magnetic. It is diamagnetic. The real nail in the coffin is the fact that the we get the same results using non metallic objects. What you also fail to acknowledge is the thing that Foucault did was not just to predict that a pendulum would undergo precession, but also to predict which way the precession would go, and how rapidly, depending on the latitude of the observer. So are you seriously gonna sit there and try to claim earths magnetic field is causing this? Really? Ask yourself, do you really think the force applied to the pendulum would just so happen to be perfect in which it produces a deviation in the swing of the pendulum which near perfectly matches the exact deviation in the pendulums swing we would expect to see if it is at that exact latitude on a spherical rotating earth. Which then allows him to almost perfectly predict his latitude as well as his distance to the the North Pole. NO. The chances of this perfectly matching up would be near zero. The magnetic field strength of earth at this position, the magnetic field strength of the pendulum, the magnetic flux passing through the pendulum, Magnetic reluctance of the pendulum, the amount of energy lost as heat through magnetic induction and many many more factors would all have to perfectly sum to just coincidentally produce a force which we would expect to see on the pendulum if the earth was spherical and rotating at the rate it is at that position.

If you are going to reply, I better see some electromagnetism principles and calculations to show these results can be produced and based off values such as the ones I listed earlier will produce the exact results in this experiment.
@Zakir Khan You mentiond it was caused merely by the RMF effect, if that were the case, then the time of one pendulum rotation would depend on where you are located on the chosen latitude - and it doesn't. Also, the precession shouldn't be the same for all materials. In other words, the deflection of a 20 kg lead weight shouldn't be the same as a 20 kg brass one. And if you make it out of cast iron (which is far more strongly influenced by it) it should be wildly different. This difference is not observed experimentally. The real strength of the Foucault pendulum comes when you repeat the experiment so that all these tiny parasitic forces ought to be randomly different, but the precession period turns out to be exactly the same, and then you repeat it in a city at a different latitude and the precession period is different by the right amount. Oh and I almost forgot to mention, that a foucault pendulum set up at the equator will show no precession at all! The physics of a simple pendulum are not dependant on the material. I've seen them being done with all types of things from styrofoam, wood, stone, marble, steel, brass, lead, quartz etc. Here is good video demonstration of a wood and styrofoam pendulum, and as you can see, the physics remain the same. ruclips.net/video/LHUXlY2qNJU/видео.html
@Zakir Khan I cited you to the video that clearly shows the physics remain the same. As you can see the time period of a pendulum is T = 2π√(L/g) therefore The time period of oscillation is independent from the mass or type of pendulum. It depends only on the length of string and value of acceleration due to gravity. Meaning even if you change the Bob with any type of material, the time period will be constant. Here is another video that discusses that. ruclips.net/video/h_eR7FJ_vkM/видео.html This is all well documented stuff. With that being said perhaps you can explain some of the points I made in my previous comments? I am interested in what you have to say about them. Thanks.
@@gerardoquinones6752 : Does this account for the earth not being a perfect sphere? Movement and influences of near celestial bodies[ Moon]? Are they negligible?
Nice experiment. Thanks for publishing it. I may try it myself sometime. If I do it maybe I'll use a laser pointer instead of marker, and then I'll take a pictures of where where the light intersects the ground. My attempt to explain the formula for those curious - a pendulum can be thought of as a device that measures rotation around it's vertical axis. If it's at the North or South pole it will measure that the rotation about it's vertical axis is 15° / hour (one rotation per day) because in that case the Earth's axis is lined up with the pendulum's vertical axis. In other cases you need to figure out how much of Earth's rotation (a vector pointing North) is lined up with the pendulum's vertical axis. In other words the pendulum will measure the vertical component of the rotation. sin(latitude) is the trig function to figure this out. This is similar to being told that something is moving North East at a certain angle at a certain speed, but you want to figure out how fast it's moving North.
You are missing the point of that motor completely. The motor is there to keep the rotation going, but more importantly, going in the ‘right’ direction… Foucault came up with a chaotic system for his deceit, because a chaotic system can easily be perturbed to do exactly what you want it to do. Earth is stationary: Airy’s failure, Michelson & Morley, and all similar experiments after prove that; the aether (‘heavens’) are what is rotating. That is why a RLG shows a drift, but a mechanical gyro does not. The movement of the aether effects the light in thr RLG. Einstein the Rosicrucian did a great job deceiving the masses and his colleagues coming up with his theories that need an aether to work, but selling it as if they don’t…
@@duncanvantongeren4646 LOL.. youe RLG claim.. I know your Flat Earth claims better than you.. Its 15 degree drift has been explained away by aether drive. M&M and Airy's FAILURES were a failure to detect ether moving.. ooops citing something but not understanding what was actually found. and as for mechanical gyro not detecting rotations.. Might want to look into a MECHANICAL GYRO-COMPASS. its a Gyroscope that finds TRUE north based entirely around Earth Rotation & gyroscopes precessing under a torque. You are really good at parroting BS you hear. might actually want to learn some science & do your OWN research.
@@duncanvantongeren4646 you really have not looked into this have you.. typical FE.. If the results contradict your belief... Just dismiss them away without truly looking into it. Must be a nice reality to live in.. Can deny any evidence that contradicts what you think.
That is true, but a longer rope means the bob doesn't go as high for the same horizontal displacement. Our pendulum was only moving up and down by an inch or so. If the rope had been shorter, it would have been a larger displacement.
The only other thing I can think of is to be careful with the pendulum bob. If it's heavy there's always the possibility of snapping the string. That could really hurt if it lands on someone. Do you mind if I ask how you found the video? I got a significant bump in subs today and was curious where they all came from.
@@eschu001 no, because they keep complaining about the dark circles around his eyes. As if some people don't just naturally inherit that issue from a parent, I guess. 🙄😒
Damn Its too bad I was late on this one. I'm a surveyor and I was going to suggest a solar observation. This is how we were able to accurately (within .01 degrees) get our latitude in South America without the use of gps. You need a compass and a theodolite, or some kind of device, even a piece of paper which has regular angles and can function as a sextet. Your back-sight direction is the compass' apparent north as close as you can get. When the sun comes up in the morning you have to measure the distance between true north and the center of where the sun rises on your horizon. As with all surveying the idea is to end up with a triangle, between true north, where the sun rises and the point you are currently at. In order to be accurate multiple observations must be made over several days, and you have to know what calender day and month it is where you are these things take a lot of the errors out of your observation. If you don't have the date, you can actually extrapolate it from doing lunar and stellar observations at night. It is a method that takes some basic hand tools but is truly the "old" school way to do it and how our ancestors navigated for thousands of years to colonize the entire earth. The sun moon and stars
Exactly! Now how does that show the shape of what you walk about on? Looking at the sky to find your position on the ground tells you nothing about the shape of the ground. You do appreciate that? You can be under a dome on a startionary, flat suface and your observations still work as you expect as long as the sky moves as you expect? Feel free to show why they don't. I suggest you do some investigation first. Try showing that the physical earth is actually moving with direct tests and I will start to be interested in what you say. It can be done! :)

Years ago I observed the Foucault Pendulum at Chicago's museum of science and industry. I didn't realize until now the swing is an arc. I'm glad I watched your video.
Great demonstration. Will a motorized gyroscope on a gimbal exhibit the same behavior? Many flat earthers claim they don't move, and thus conclude that that proves the earth doesn't move. I haven't done that experiment myself yet. Thanks.
VoysovReason yes i have try at home this experiment and don't have detect earth rotation. I have see that hooking on the ceiling is very very important. 60% of time rotate anticlockwise, 20% don't rotate and 20% rotate in clockwise. It is not reliable experiment ruclips.net/video/e0P2IWNSqZM/видео.html
In principle it should. One however has to be careful to avoid all possible unintended restraining forces like those that might be delivered by power leads. I believe such forces are the cause of the flat-earthers’ false negative results. I have, on-and-off, given some thought as to how power can be delivered wirelessly to a motorized gyroscope wheel in a free gimbal for this very purpose. I formally retire next year so I will have time to design and execute.
@@THETRUTHZ All of the construction. It's not even comparable - different materials used to construct both of these, different lenghts of string (which is very important at this Foucault's pendulum), different forces, just everything. To build a proper Foucault's pendulum you have to meet some required conditions which this thing from your video doesn't meet. It's a matter of scale, it's a matter of weight (compare heavy sphere to a plastic bottle). Even the strings are different - in this video we can see just one string to which a sphere is attached, on your video there are two strings above. Well, yeah...
@@THETRUTHZ Long story short: to make it works you need quite a long string and a heavy object attached at it's end. Atleast. And it's not the same as some string and plastic bottle with some sand.
Nice touch to use Carl Orff’s Carmina Burana as dramatic music for the swinging pendulum. It really is dramatically important to consider the implications of the pendulum’s precession.
This experiment disproves the FE theory in two ways: 1. that the earth is a sphere. 2. that it rotates relative to the universe. Many FEers believe the earth is stationary as well as flat.
If you have a long enough cable and a heavy weight, it will swing for several hours before stopping. Doing anything to keep it moving would invalidate the experiment.
@@my3dviews not really, if you have a magnetic ring at the fixation point in the ceiling , it will give it enough force to keep the momentum going and not modify the trajectory
@@my3dviews think of it like a sliding magnetic puck on a circular plane of ice which has opposite pole magnet walls , when it gets pushed back by the wall it comes back in the same direction; if you start the slide on the diameter line ; and as you spin the plane the puck will always go on the diameter line , same goes with the scale of the planet and a foucault pendulum
@@echoMV13 If you are talking about two permanent magnets, then that can't keep it going, since that would be a perpetual motion machine.

Awesome, have fun. A heads up, even so called 'static' cord stretches a lot when it's that long. You may need a short stepladder to attach the bob so in hangs just above the floor.
Loved it, thank you. But should we pronounce his name "Foucault" (Anglicised) or "Foucou" (French)? If we want to use proper name pronunciation in the native language, how do we say Copernicus? Magellan? Even Columbus? Much more challenging and most listeners will have no idea.
By the way, in the case of Magellan, it isn't even the correct "native" spelling, which is Magalhães. Now try to pronounce that without knowing Portuguese! 😉
Sir, you truly are a gentleman physicist. I learned something! I was slightly off in a claim I made about the Pendulum and can now correct it. I am having one difficulty. I can see a Pendulum as a 24 hour clock directly under the Pole, but it is harder at lower latitudes. It would not work at all at the equator. But, why exactly is 24 divided by the sine of latitude? Could you make a mathematical video showing that?
+CHistrue Honestly the math is pretty dry, and quite long. :P At it's most basic it's the result of using Newton's Laws and some vector calculus. I believe the Wikipedia article on the subject covers it.
The Gentleman Physicist Conservation of angular momentum? Does that cover the "big picture" aspect of it? I would imagine that as I move toward the poles the conservation of angular momentum would require that my pendulum "spin" faster...but how to fit it mathematically is where it is hard to concentrate at 10:30 PM! In any case, good night sir!
Very good question and the answer is yes. It would make a complete 360° in 24 hours instead of the 31 hours shown in this video. And when it takes an infinite amount of hours (meaning, it does not turn at all, only swings back and forth), you know you are at the equator: There, the pendulum swings in the same plan as that of the earth's rotation.
6 лет назад+2
cristian draghici Your picture shows the rotation speed along the surface of the earth, but a pendulum swinging north-south will not start to rotate at the equator. There the earth moves just sideways... The rotation of the pendulum will be best to observe at the poles, because that's the points of rotation on the earth.
At the North Pole it will take exactly 1 day to rotate 360. At 1 degree north of the equator, it will take 2 months. (On the equator it doesn't rotate.)
That demonstration is v cool! I’ve never understood how anyone could ever be a flat-earther - even pre the advent of aircraft and rockets etc., because you can clearly see the curvature of the earth at sea. As you approach an island from a distance you only see the mountaintops and as you get closer, more lower land slowly appears. You have to be reasonably close to see the shoreline. The story about Columbus’s crew fearing they would sail off the edge of the earth is probably a load of bollocks.
Did you also calculate the movement from the earth rotating the sun at 66,000mph? Or the Earths Movement following the Sun at 55,000mph? Think of the forces applied on that pendulum with is Spinning at 800mph while going another direction at 66,000mph then travelling in a straight line at 66,000mph.
Many, many years ago I read Umberto Eco's novel Foucault's Pendulum. Whilst it made a big impression on me I admit I did not understand everything he wrote. Thank's to this brilliant video I am inspired to read it again.
I love that it is so simple that ANYONE can do it with little preparation. Can any link to FE videos where the FE guys do a pendulum test and show it does not work?
E I N S I was debated to three flat earthers, all said "you were fooled by hoaxters" "masons told it to you" "it is not observable" "it is powered" "it proves nothing". That's funny how do they afraid of actual science.

so whats rotates the pendulum or the floor below it?????....and if its the floor then the ceiling cant be moving as well because thats what the pendulum is connected to which doesn't prove anything
It is on a string that allows it to in effect be free from the ceiling. If it were a solid object that did not allow the pendulum to stay on trajectory, like a stick, then you would be correct. ;)
+Loud beatz Watch this video to see why you're wrong. It demonstrates how a pendulum rotates independent of the attachment above. It's a Hydraulic Press Action vid by the way /watch?v=EDpLcDlgQis
@@TempleOvBlackLight So given your assumption that the object is free of the earth's rotation, we should be able to apply this science to all things flying through the sky. Air travel would be dramatically shortened simply by going the opposite direction to the earth's spin. But that doesn't happen in reality,
so, pendulum makes 360 degrees in 24h? from noon to noon? so, where is that 1 degree extra what earth need for noon to noon rotation? we know that noon to noon rotation of the earth takes that lil more than 360 degrees so we do not end up that in 6 month noon is actually a midnight... why pendulum reverse rotation during the eclipse?
+Zo Mi The period of the pendulum is only 24 hours at the north and south pole it get's longer as you near the equator. I'm not sure I understand the rest of what you said. An eclipse won't change the direction of the pendulum.
The Gentleman Physicist it is recorded that pendulum changed its rotation direction during eclipse in several occasions. pendulum should complete 360 degree circle in 23h56min and few sec, in 24h should gain 361degree to achieve noon to noon rotation.
You are correct, but the 360 degrees of rotation would happen only at the poles and it would take one sidereal day, which is 23 h 56 m 4.1 s. People usually just simplify it by saying 24 hours. Accurate calculations of a Foucault Pendulum always use a sidereal day. www.brown.edu/Departments/Italian_Studies/n2k/visibility/Alison_Errico/Soft%20Moon/pendulum.html
+Zo Mi Scientists are still investigating why there is an interference to the pendulum's motion when there is a solar eclipse. Mind you, this interference is not always present and not always the same. But the interference is striking. You can download one of the many papers on this issue here: www.hindawi.com/journals/aa/2012/263818/ The time it takes for a pendulum to make a full rotation depends on where you are on earth. It is 24 hours on the poles but on the equator it does not rotate at all.
Does the pendulum stand still if there is no initial force applied? If I spin something it eventually stops. The rotation of Earth is not a constant. The North Pole is moving, Earth is also travelling behind the Sun and the Sun, and Spiral arm and Galaxy are all moving.

use your discernment folks, right why isn't the pendulum in the same spot after 24h, how do you know metal isn't affected (actually, isn't it!?), how come no examples of marble or something else?, and does that f. pendulum even mean that about the spin? how come we don't see it move already if we're spinning, on and on and other stuffs too :P how come we can see so far (refraction doesn't explain it fully), how do we have gas pressure next to a vacuum, good luck showing rotation, etc...
as for 24hrs.. If the experiment is done correctly like this one, the pendulum would slowly stop due to air resistance before the 24hrs. also, the precession is dictated by ones latitude.. It is only at the Poles does it precess at one revolution in 24hrs. otherwise it is slower . And if it were assisted by some mechanical means to keep it running for 24hrs you would cry fool..
You was use inaccurate value for day length. For Foucault's Pendulum it is not 24h, but only 23.934 hours (sidereal day) Therefore your result is latitude 49.7 = error 1.3 degree.
Globetards are crying way more when they realize that if the Earth actually moved under a pendulum, it'd have to also move under everything else that's not attached to it, at a speed of over 1k mph at the equator...

The Foucault pendulum is NOT a perpetual motion machine. Because of air friction the pendulum would eventually stop 🛑 swinging, but a magnet encircling the cable, pulls on the cable with each swing. Electric current controlling the magnetism is turned on and off with each swing of the pendulum.

The trick is the mass of the bob and the thickness of the string. That sphere of lead weighed about 50lbs and the string was very thin. It meant friction dampened the system very slowly. Out of curiosity how did you find the video? I got a significant bump in subs today. Cheers
In my opinion the foucault pendulum does not at all prove the earth is spinning. For one thing, they tell us that everything spins with the earth, so with that theory the pendulum shouldn't move at all, it would just rotate with the earth, rotating the same speed as everything within the earths atmosphere and just draw a straight line, not a circle. There could be many other reasons why the pendulum rotates. Electro magnetism is just one other idea of many. If you are standing on the equator, you are supposedly spinning at just over 1000 miles per hour, If you took a plane and landed close to the north pole you'd be spinning at close to zero mph! are we supposed to believe that we can not feel or sense any kind of speed reduction or movement but in a car you can detect the slightest movement of reduction/acceleration? Im not buying it
+mojo jojo The key component of your last statement is that in a car you can feel the acceleration, not velocity. The force that you feel when a car speeds up or slows down is due to newton's second law, specifically that the sum of all of the forces acting on an object is equal to that object's mass times its acceleration, NOT velocity. You are correct in saying that there is a difference in velocity between the equator and the north pole, and if you teleported from the equator to the pole then you would most certainly feel the change in velocity. Using conventional transportation, the amount of change in your velocity per second, or acceleration, is far too minute for the human body to detect. This tiny acceleration is precisely why the pendulum takes so long to turn around. Oh and by the way, I want to complement you on your critical thinking about the differences in velocity between the equator and the poles. This kind of thinking is exactly what I look for in the physics students that I teach.
+mojo jojo It is not the speed of the Earth that effect the pendulum, but the period of rotation. The pendulum tries to swing in the same plane, but as the Earth rotates, the plane that the pendulum swings in appears to rotate from the Earth's perspective. If you did the experiment on either of the poles, it would swing back and forth in the same plane with the Earth rotating underneath it. So yes it does prove the Earth is rotating. Also, it cannot be caused by electromagnetism, since it will also work with a non metallic pendulum, which is not influenced by magnetism.
+AbuserTube: if what you said is true, then what we are told about how the Earths atmosphere spins all at the same speeds as Earth can't be true. If the pendulum itself is attached to the earth, then the spin should have no effect on it if the pendulum that is moving freely is within the Earths atmosphere. I hope that makes sense as to what Im thinking. And if the pendulum isnt effected by the spinning atmosphere, then this would prove the Coriolis Effect bunk...which, I believe, it is.
+AbuserTube One more thing. It doesn't have to be metallic to be effected by electromagnetism. For instance salt water is greatly effected. Even regular tap water is slightly, but not as much as salt water
mojo jojo You are misunderstanding how it works. If you have the pendulum swinging in a large room the Earth's atmosphere is moving with the room and the pendulum. If you did it at the pole the pendulum would swing in the same plane, the room would rotate with the Earth as would the air in the room. The heavy pendulum would not be affected by the fact that the air in the room rotated with the room once per day. Air is too thin for it to affect the heavy pendulum. At the equator the air moves a the same speed as the Earth, so it would not affect the pendulum, and the rotation of the Earth also would not affect it there, so it would swing in one plane. At the south pole it would rotate over one day in the opposite direction as at the north pole. In between the poles and the equator, it would depend on the latitude. This has been proven over and over, as this video demonstrates. If the Earth did not rotate, then the pendulum would swing back and forth in one plane everywhere on the Earth.
This truly fabulous. In all honesty i can see and understand what is being presented but i will need some more time to read and properly understand how this actually works. But i understand the basics of the principle. What an amazing demonstration of a small piece of some the actions and motions that occur continually in this reality we live in on planet Earth!
MyITRcom well that could be any number of reasons but it is confirmed that pendulums are affected by the "allais?" Effect, which makes them act weird. I've heard it say they go the wrong direction quite a bit of the time too. Basically the answer isn't totally clear but the results are not clear.
lol...If this pendulum works how they say it works. You should be able to get in a helicopter in Charlotte NC. Lift off the ground for 3 hrs and land in California.
No, not true. The atmosphere moves with the Earth, and the helicopter moves with the air. Plus it has the same inertia as the Earth does. It doesn't just stop because it lifts off of the ground.
Unlearn and Relearn The pendulum isn't suspended by air, like the helicopter, so not a good comparison. If you put a Foucault pendulum at the North Pole and observed it from above the atmosphere, it would swing in one plane, with the Earth rotating under it. For an observer on Earth, the pendulum's angle of swing appears to rotate throughout the day. The effect of the atmosphere rotating once per day would be negligible. Comparing that to a helicopter that hovers within the atmosphere is ridiculous. The helicopter will move with the atmosphere since it has the same momentum as the Earth and the atmosphere moves with the Earth. Your first comment suggested that a hovering helicopter will for some reason not move with the Earth or the atmosphere, but stay in one place. If you take a model helicopter on a train and hover it, it would still move with the train, since it has the momentum of the train and the air inside moves with it. Get it?
Fire isn't only more interesting, it is almost essential as the start of the pendulum must be absolutely as smooth as possible for the experiment to work. Any disturbance in the start and you're swing may not be entirely linear (a slight oval instead) and that throws off the experiment. You can also easily tell northern or southern hemisphere by visiting the restroom and flushing a toilet and observing the direction of the Coriolis effect.
I remember Easter Sunday weekend 1974, a buddy and I rented a car in Newport News whee we were attending the transportation school at Ft Euistis, VA, visited the Smithsonian and they had a Pendulum hanging from the big open space, it was knocking over domino size blocks with each swing. This was the old original Smithsonian, before the Air and Space Museum was built. ]

Option 1 (reality) is that Earth is a rotating sphere. This experiment is consistent with that idea and proposing that you don't notice a 0.2% weight difference when travelling from a pole to the equator seems reasonable (haven't actually checked the math but let's take a huge leap and assume you did it correctly). Everything you can observe is consistent with a rotation spherical Earth.
Option 2 (your proposition) is that a massive magnetic field rotates somewhere beneath or above the flat Earth to make the pendulum move and for some reason isn't detected and doesn't interact with other metals in the same way and rotates the other way south of the equator. On top of that you propose that you would notice a weight difference that is equivalent of eating an egg.
You honestly think option 2 is reasonable?

the problem is assuming a globe model in the first place. If we have numbers for an assumed size of a ball then of course this math will work out. Why did you have to manually start the pendulum in the first place. Wouldn't the force of the rotation of the earth cause the pendulum to perform its movement.

Flatards complain that Foucault's pendulum is artificially made rotate in the museums by having it powered, they are just powered to avoid them from stopping.\
Well, here it is, a non-powered pendulum showing Earth's rotation.
While this was a great experiment, you have to be kidding yourself if you think it was not "powered". Even if the string was loose, which it wasn't,. This sets it off to the velocity formula. I bet you can calculate how long it would take before that mass comes to rest. Sorry, but this is not motion by spinning of the earth, and I think the person doing the video is not claiming such, as he knows it is not happening. You also have to look into Jefemenko's field theory explanations, and this fall along. As we also have to factor in true north azimuth magnetic north. SO these things are NOT very scientific FROM THE GET GO! We have MUCH better tools today. Why not use these tools vs the 200 year or 2000(Eratosthenes) year old methods? Mind boggling!! Takes a bit more money, but much less setup and time, with NO variables that start from a WRONG tangent. Now I think doing the test IS very praise worthy, and encouraging to know. But the conclusions we draw from these are very dangerous. We feed our ego, and our false sense of understanding in a dogmatic manner. This needs to stop.
@Alan J try chewing in sections, and you might understand it. Be warned, each bite is a lot to chew. If you can follow all of it, then just adhere to the conclusion. Size is not a factor in this.
@Yute firstly aeroplanes would be slightly affected by this phenomena, it would just be so small. Comparable to a minor breeze which they would constantly be manually and/or automatically correcting for anyway. So whether or not this force is actually effecting the plane doesn't make a difference because it would be indistinguishable from other factors affecting the plane.
And really? You're seriously going to sit there and claim earths magnetic field is causing this. You think the force applied to the pendulum would just so happen to be perfect in which it produces a deviation in the swing of the pendulum which near perfectly matches the exact deviation in the pendulums swing we would expect to see if it is at that exact latitude on a spherical rotating earth. Which then allows him to almost perfectly predict his latitude.
NO. The chances of this perfectly matching up would be near zero. The magnetic field strength of earth at this position, the magnetic field strength of the pendulum, the magnetic flux passing through the pendulum, Magnetic reluctance of the pendulum, the amount of energy lost as heat through magnetic induction and many many more factors would all have to perfectly sum to just coincidentally produce a force which we would expect to see on the pendulum if the earth was spherical and rotating at the rate it is at that position. Yeah no, not gonna happen.
If you're so confident magnetic fields are producing this effect perfectly to match which predictions of the globe earth you should be able to explain and calculate how. If you are going to reply to this I better see some electromagnetism principles and calculations to show these results can be produced and based off values such as the ones I listed earlier will produce the exact results in this experiment otherwise everything you are saying is no more than stupid claim to make the flat earth idea seem worthy.
And lets just for this situation assume you are correct about the increase in the speed of individuals on earth because you clearly have no knowledge of the principles of relative motion, but let's just assume you are correct. Firstly we do not feel velocity we feel acceleration. So based on the acceleration of 2.15 cm/s/s, that is
0.0215 m/s/s, an acceleration like that would equivalent of accelerating roughly from 0 to 28 m/s or 0 to 100km/h
in just under 22 minutes. That shit is nothing, you would feel more force if a bug flew into your face. What I am saying is it is not noticeable.
Remember if you're going to reply don't forget those calculations and more detailed explanations with actual supporting data.

What I liked about this video is that you can see the pendulum without the magnets around ( that people may have suspicions that are manipulating the pendulum ) and the extraction of latitude from really measuring it!
The period T for a pendulum is NEARLY independent of amplitude, especially when θ is less than about 15º. For a large amplitude, T = 2π square root of √L/g is less correct, and the exact equation gets complicated. So there are reasons for the small error in the video.
OK
Also it wasn't a dumb question, we weren't sure if the high tension string we used was thin enough to avoid slowing the pendulum due to air friction. Turns out it worked really well. :)

@Zakir Khan
I'm interested in how you came to that conclusion. The bob was made of lead. Which is not magnetic. It is diamagnetic. The real nail in the coffin is the fact that the we get the same results using non metallic objects. What you also fail to acknowledge is the thing that Foucault did was not just to predict that a pendulum would undergo precession, but also to predict which way the precession would go, and how rapidly, depending on the latitude of the observer.
So are you seriously gonna sit there and try to claim earths magnetic field is causing this? Really? Ask yourself, do you really think the force applied to the pendulum would just so happen to be perfect in which it produces a deviation in the swing of the pendulum which near perfectly matches the exact deviation in the pendulums swing we would expect to see if it is at that exact latitude on a spherical rotating earth. Which then allows him to almost perfectly predict his latitude as well as his distance to the the North Pole. NO. The chances of this perfectly matching up would be near zero. The magnetic field strength of earth at this position, the magnetic field strength of the pendulum, the magnetic flux passing through the pendulum, Magnetic reluctance of the pendulum, the amount of energy lost as heat through magnetic induction and many many more factors would all have to perfectly sum to just coincidentally produce a force which we would expect to see on the pendulum if the earth was spherical and rotating at the rate it is at that position. Yeah no, not gonna happen.

@Zakir Khan
You mentiond it was caused merely by the RMF effect, if that were the case, then the time of one pendulum rotation would depend on where you are located on the chosen latitude - and it doesn't. Also, the precession shouldn't be the same for all materials. In other words, the deflection of a 20 kg lead weight shouldn't be the same as a 20 kg brass one. And if you make it out of cast iron (which is far more strongly influenced by it) it should be wildly different. This difference is not observed experimentally.
The real strength of the Foucault pendulum comes when you repeat the experiment so that all these tiny parasitic forces ought to be randomly different, but the precession period turns out to be exactly the same, and then you repeat it in a city at a different latitude and the precession period is different by the right amount. Oh and I almost forgot to mention, that a foucault pendulum set up at the equator will show no precession at all!
The physics of a simple pendulum are not dependant on the material. I've seen them being done with all types of things from styrofoam, wood, stone, marble, steel, brass, lead, quartz etc. Here is good video demonstration of a wood and styrofoam pendulum, and as you can see, the physics remain the same.
ruclips.net/video/LHUXlY2qNJU/видео.html
@Zakir Khan no I showed you that the physics are the same. You however, failed to address any one of my points.
@Zakir Khan
I cited you to the video that clearly shows the physics remain the same.
As you can see the time period of a pendulum is T = 2π√(L/g) therefore The time period of oscillation is independent from the mass or type of pendulum. It depends only on the length of string and value of acceleration due to gravity. Meaning even if you change the Bob with any type of material, the time period will be constant.

This is all well documented stuff. With that being said perhaps you can explain some of the points I made in my previous comments? I am interested in what you have to say about them. Thanks.
The maximum difference between geodetic and geocentric latitude occurs at 45 degrees North and South. That accounts for 0.2 degrees error.

That's the best compliment I've gotten since I started YouTubing :)
Nice experiment. Thanks for publishing it. I may try it myself sometime. If I do it maybe I'll use a laser pointer instead of marker, and then I'll take a pictures of where where the light intersects the ground. My attempt to explain the formula for those curious - a pendulum can be thought of as a device that measures rotation around it's vertical axis. If it's at the North or South pole it will measure that the rotation about it's vertical axis is 15° / hour (one rotation per day) because in that case the Earth's axis is lined up with the pendulum's vertical axis. In other cases you need to figure out how much of Earth's rotation (a vector pointing North) is lined up with the pendulum's vertical axis. In other words the pendulum will measure the vertical component of the rotation. sin(latitude) is the trig function to figure this out. This is similar to being told that something is moving North East at a certain angle at a certain speed, but you want to figure out how fast it's moving North.
great, thanks for your fantastic work!
Thanks for this. My wife and I are amazed by the accuracy you achieved with something so simple. Nice job!

2:45 Mathematics ALWAYS deserves dramatic music.
Flat earthers always claim all Foucault experiments have used a motor.. Thanks for showing the "REAL" way it was originally done..
You are missing the point of that motor completely. The motor is there to keep the rotation going, but more importantly, going in the ‘right’ direction…
Foucault came up with a chaotic system for his deceit, because a chaotic system can easily be perturbed to do exactly what you want it to do.
Earth is stationary: Airy’s failure, Michelson & Morley, and all similar experiments after prove that; the aether (‘heavens’) are what is rotating.
That is why a RLG shows a drift, but a mechanical gyro does not. The movement of the aether effects the light in thr RLG. Einstein the Rosicrucian did a great job deceiving the masses and his colleagues coming up with his theories that need an aether to work, but selling it as if they don’t…

The Foucault experiment done WITHOUT a motor performs EXACTLY as predicted.

LOL.. youe RLG claim.. I know your Flat Earth claims better than you..
Its 15 degree drift has been explained away by aether drive.

and as for mechanical gyro not detecting rotations.. Might want to look into a MECHANICAL GYRO-COMPASS. its a Gyroscope that finds TRUE north based entirely around Earth Rotation & gyroscopes precessing under a torque.

This is an old comment but it was Carmina Burana
That is true, but a longer rope means the bob doesn't go as high for the same horizontal displacement. Our pendulum was only moving up and down by an inch or so. If the rope had been shorter, it would have been a larger displacement.
How could it swing for over 40 minutes?
The only other thing I can think of is to be careful with the pendulum bob. If it's heavy there's always the possibility of snapping the string. That could really hurt if it lands on someone.

Damn Its too bad I was late on this one.
I'm a surveyor and I was going to suggest a solar observation. This is how we were able to accurately (within .01 degrees) get our latitude in South America without the use of gps. You need a compass and a theodolite, or some kind of device, even a piece of paper which has regular angles and can function as a sextet. Your back-sight direction is the compass' apparent north as close as you can get. When the sun comes up in the morning you have to measure the distance between true north and the center of where the sun rises on your horizon. As with all surveying the idea is to end up with a triangle, between true north, where the sun rises and the point you are currently at. In order to be accurate multiple observations must be made over several days, and you have to know what calender day and month it is where you are these things take a lot of the errors out of your observation. If you don't have the date, you can actually extrapolate it from doing lunar and stellar observations at night.
It is a method that takes some basic hand tools but is truly the "old" school way to do it and how our ancestors navigated for thousands of years to colonize the entire earth. The sun moon and stars
Exactly! Now how does that show the shape of what you walk about on? Looking at the sky to find your position on the ground tells you nothing about the shape of the ground. You do appreciate that? You can be under a dome on a startionary, flat suface and your observations still work as you expect as long as the sky moves as you expect? Feel free to show why they don't. I suggest you do some investigation first. Try showing that the physical earth is actually moving with direct tests and I will start to be interested in what you say. It can be done! :)

Great demonstration. Will a motorized gyroscope on a gimbal exhibit the same behavior? Many flat earthers claim they don't move, and thus conclude that that proves the earth doesn't move. I haven't done that experiment myself yet. Thanks.
VoysovReason yes i have try at home this experiment and don't have detect earth rotation.

Foucault tried the gyroscope method alo - actually before the pendulum.
In principle it should. One however has to be careful to avoid all possible unintended restraining forces like those that might be delivered by power leads. I believe such forces are the cause of the flat-earthers’ false negative results.
I have, on-and-off, given some thought as to how power can be delivered wirelessly to a motorized gyroscope wheel in a free gimbal for this very purpose. I formally retire next year so I will have time to design and execute.

To build a proper Foucault's pendulum you have to meet some required conditions which this thing from your video doesn't meet. It's a matter of scale, it's a matter of weight (compare heavy sphere to a plastic bottle). Even the strings are different - in this video we can see just one string to which a sphere is attached, on your video there are two strings above. Well, yeah...

@@tubular618 It is.
they did not tell us any thing about how to keep it swining
If you have a long enough cable and a heavy weight, it will swing for several hours before stopping. Doing anything to keep it moving would invalidate the experiment.
@@my3dviews not really, if you have a magnetic ring at the fixation point in the ceiling , it will give it enough force to keep the momentum going and not modify the trajectory
How exactly does a magnetic ring keep a pendulum swinging without affecting the trajectory?
@@my3dviews think of it like a sliding magnetic puck on a circular plane of ice which has opposite pole magnet walls , when it gets pushed back by the wall it comes back in the same direction; if you start the slide on the diameter line ; and as you spin the plane the puck will always go on the diameter line , same goes with the scale of the planet and a foucault pendulum
@@echoMV13 If you are talking about two permanent magnets, then that can't keep it going, since that would be a perpetual motion machine.

By the way, in the case of Magellan, it isn't even the correct "native" spelling, which is Magalhães. Now try to pronounce that without knowing Portuguese! 😉
The opening joke was a blockbuster.
Thank you, sir.
Sir, you truly are a gentleman physicist. I learned something! I was slightly off in a claim I made about the Pendulum and can now correct it.
I am having one difficulty. I can see a Pendulum as a 24 hour clock directly under the Pole, but it is harder at lower latitudes. It would not work at all at the equator. But, why exactly is 24 divided by the sine of latitude? Could you make a mathematical video showing that?
+CHistrue Honestly the math is pretty dry, and quite long. :P At it's most basic it's the result of using Newton's Laws and some vector calculus. I believe the Wikipedia article on the subject covers it.
The Gentleman Physicist Conservation of angular momentum? Does that cover the "big picture" aspect of it? I would imagine that as I move toward the poles the conservation of angular momentum would require that my pendulum "spin" faster...but how to fit it mathematically is where it is hard to concentrate at 10:30 PM!
In any case, good night sir!
Maybe the poles were shifting?
what amazing oh , that is incredible ,the science is every things ..
What science was used then.
so would happen if this was done at the north pole? does it move faster?
cdn.wonderfulengineering.com/wp-content/uploads/2017/02/earth-rotation-1.jpg
Very good question and the answer is yes. It would make a complete 360° in 24 hours instead of the 31 hours shown in this video. And when it takes an infinite amount of hours (meaning, it does not turn at all, only swings back and forth), you know you are at the equator: There, the pendulum swings in the same plan as that of the earth's rotation.
cristian draghici
Your picture shows the rotation speed along the surface of the earth, but a pendulum swinging north-south will not start to rotate at the equator. There the earth moves just sideways... The rotation of the pendulum will be best to observe at the poles, because that's the points of rotation on the earth.
At the North Pole it will take exactly 1 day to rotate 360. At 1 degree north of the equator, it will take 2 months.
(On the equator it doesn't rotate.)
Remember this exercise from school. We went to a church (high ceiling) and performed the experiment there. It's amazing when you first see this.
That demonstration is v cool! I’ve never understood how anyone could ever be a flat-earther - even pre the advent of aircraft and rockets etc., because you can clearly see the curvature of the earth at sea. As you approach an island from a distance you only see the mountaintops and as you get closer, more lower land slowly appears. You have to be reasonably close to see the shoreline. The story about Columbus’s crew fearing they would sail off the edge of the earth is probably a load of bollocks.

Did you also calculate the movement from the earth rotating the sun at 66,000mph? Or the Earths Movement following the Sun at 55,000mph? Think of the forces applied on that pendulum with is Spinning at 800mph while going another direction at 66,000mph then travelling in a straight line at 66,000mph.
So you were a ZERO in math and science in high school.
You comment here to announce that.

Currently they are acknowledging that these phonomena are real but come up with very elaborate reasons to explain them.

How do you isolate the independent variable for removal and introduction to test the hypothesis?

The precession of the pendulum VARIES as a function of its latitude.
You're welcome.
so whats rotates the pendulum or the floor below it?????....and if its the floor then the ceiling cant be moving as well because thats what the pendulum is connected to which doesn't prove anything
It is on a string that allows it to in effect be free from the ceiling. If it were a solid object that did not allow the pendulum to stay on trajectory, like a stick, then you would be correct. ;)
Loud beatz another meth addict.
you have to think bro...
+Loud beatz Watch this video to see why you're wrong. It demonstrates how a pendulum rotates independent of the attachment above. It's a Hydraulic Press Action vid by the way /watch?v=EDpLcDlgQis
@@TempleOvBlackLight So given your assumption that the object is free of the earth's rotation, we should be able to apply this science to all things flying through the sky. Air travel would be dramatically shortened simply by going the opposite direction to the earth's spin. But that doesn't happen in reality,
so, pendulum makes 360 degrees in 24h? from noon to noon? so, where is that 1 degree extra what earth need for noon to noon rotation? we know that noon to noon rotation of the earth takes that lil more than 360 degrees so we do not end up that in 6 month noon is actually a midnight... why pendulum reverse rotation during the eclipse?
+Zo Mi The period of the pendulum is only 24 hours at the north and south pole it get's longer as you near the equator. I'm not sure I understand the rest of what you said. An eclipse won't change the direction of the pendulum.
The Gentleman Physicist
it is recorded that pendulum changed its rotation direction during eclipse in several occasions.
pendulum should complete 360 degree circle in 23h56min and few sec, in 24h should gain 361degree to achieve noon to noon rotation.
You are correct, but the 360 degrees of rotation would happen only at the poles and it would take one sidereal day, which is 23 h 56 m 4.1 s. People usually just simplify it by saying 24 hours. Accurate calculations of a Foucault Pendulum always use a sidereal day. www.brown.edu/Departments/Italian_Studies/n2k/visibility/Alison_Errico/Soft%20Moon/pendulum.html
where is it "recorded" ??
+Zo Mi
Scientists are still investigating why there is an interference to the pendulum's motion when there is a solar eclipse. Mind you, this interference is not always present and not always the same. But the interference is striking.
You can download one of the many papers on this issue here:
www.hindawi.com/journals/aa/2012/263818/
The time it takes for a pendulum to make a full rotation depends on where you are on earth. It is 24 hours on the poles but on the equator it does not rotate at all.
The earth spins at 15° per hour. Thanks Bob.
Carmina Burana and Physics. I love it!
Does the pendulum stand still if there is no initial force applied? If I spin something it eventually stops. The rotation of Earth is not a constant. The North Pole is moving, Earth is also travelling behind the Sun and the Sun, and Spiral arm and Galaxy are all moving.

My advice for you involves more science books and fewer flat-earth videos.
your advice is not only unwarranted, it is also unwanted.
"unwarranted/unwanted" Yeah, flat Earthers don't want to understand stuff.
You would only get full rotation in 24 hours at the poles
as for 24hrs.. If the experiment is done correctly like this one, the pendulum would slowly stop due to air resistance before the 24hrs. also, the precession is dictated by ones latitude.. It is only at the Poles does it precess at one revolution in 24hrs. otherwise it is slower .
And if it were assisted by some mechanical means to keep it running for 24hrs you would cry fool..
you look tired
no , he look liar
The building the string is attached to is also turning so not sure how this works !
It is attached by a sort of universal joint which permits rotation.
This is key to a Foucault pendulum.

Look in the comments. Try sorting for newest first and then look...
You was use inaccurate value for day length. For Foucault's Pendulum it is not 24h, but only 23.934 hours (sidereal day)
Therefore your result is latitude 49.7 = error 1.3 degree.
Yes, well observed. Many people think that the earth rotates on its axis once every 24 hours, which as you point out, is not the case.

*Foucault's pendulum is NOT proof 'the world turns'.*
It's proof that the "world turns" and also (bonus feature) it's spherical.
Sadly you don't have the intellect to see it.
The Earth is not a globe.
Foucault's pendulum is a brilliant demonstration of both the Earth being a globe and rotating.
Too bad your too dim to understand that.
😂😂🤡🤡
In my opinion the foucault pendulum does not at all prove the earth is spinning. For one thing, they tell us that everything spins with the earth, so with that theory the pendulum shouldn't move at all, it would just rotate with the earth, rotating the same speed as everything within the earths atmosphere and just draw a straight line, not a circle.
There could be many other reasons why the pendulum rotates. Electro magnetism is just one other idea of many.
If you are standing on the equator, you are supposedly spinning at just over 1000 miles per hour, If you took a plane and landed close to the north pole you'd be spinning at close to zero mph! are we supposed to believe that we can not feel or sense any kind of speed reduction or movement but in a car you can detect the slightest movement of reduction/acceleration?
Im not buying it
+mojo jojo The key component of your last statement is that in a car you can feel the acceleration, not velocity. The force that you feel when a car speeds up or slows down is due to newton's second law, specifically that the sum of all of the forces acting on an object is equal to that object's mass times its acceleration, NOT velocity. You are correct in saying that there is a difference in velocity between the equator and the north pole, and if you teleported from the equator to the pole then you would most certainly feel the change in velocity. Using conventional transportation, the amount of change in your velocity per second, or acceleration, is far too minute for the human body to detect. This tiny acceleration is precisely why the pendulum takes so long to turn around. Oh and by the way, I want to complement you on your critical thinking about the differences in velocity between the equator and the poles. This kind of thinking is exactly what I look for in the physics students that I teach.
+mojo jojo It is not the speed of the Earth that effect the pendulum, but the period of rotation. The pendulum tries to swing in the same plane, but as the Earth rotates, the plane that the pendulum swings in appears to rotate from the Earth's perspective. If you did the experiment on either of the poles, it would swing back and forth in the same plane with the Earth rotating underneath it. So yes it does prove the Earth is rotating. Also, it cannot be caused by electromagnetism, since it will also work with a non metallic pendulum, which is not influenced by magnetism.
+AbuserTube: if what you said is true, then what we are told about how the Earths atmosphere spins all at the same speeds as Earth can't be true.
If the pendulum itself is attached to the earth, then the spin should have no effect on it if the pendulum that is moving freely is within the Earths atmosphere. I hope that makes sense as to what Im thinking. And if the pendulum isnt effected by the spinning atmosphere, then this would prove the Coriolis Effect bunk...which, I believe, it is.
+AbuserTube One more thing. It doesn't have to be metallic to be effected by electromagnetism. For instance salt water is greatly effected. Even regular tap water is slightly, but not as much as salt water
mojo jojo You are misunderstanding how it works. If you have the pendulum swinging in a large room the Earth's atmosphere is moving with the room and the pendulum. If you did it at the pole the pendulum would swing in the same plane, the room would rotate with the Earth as would the air in the room. The heavy pendulum would not be affected by the fact that the air in the room rotated with the room once per day. Air is too thin for it to affect the heavy pendulum. At the equator the air moves a the same speed as the Earth, so it would not affect the pendulum, and the rotation of the Earth also would not affect it there, so it would swing in one plane. At the south pole it would rotate over one day in the opposite direction as at the north pole. In between the poles and the equator, it would depend on the latitude. This has been proven over and over, as this video demonstrates. If the Earth did not rotate, then the pendulum would swing back and forth in one plane everywhere on the Earth.
woah! this is amazing! i really enjoyed this video thank you.
just realized this is a dead channel...
This truly fabulous. In all honesty i can see and understand what is being presented but i will need some more time to read and properly understand how this actually works. But i understand the basics of the principle. What an amazing demonstration of a small piece of some the actions and motions that occur continually in this reality we live in on planet Earth!
It shows that the Earth is a globe AND it rotates.
From the brain of one man in 1851.
It IS fabulous indeed.
the world does not turn
+randysmith12360 BEHOLD! the wild troll in his natural enviroment!
of course it doesn't, we're just messing with you kid, we just want you to think that it does, in fact, we live on a pancake
Nah. Whatever the shape, we're inside an enclosed space inside of deep water.
Then why would the pendulum not just stay in a straight line? I guess physics is no concern of yours?
MyITRcom well that could be any number of reasons but it is confirmed that pendulums are affected by the "allais?" Effect, which makes them act weird. I've heard it say they go the wrong direction quite a bit of the time too.
Basically the answer isn't totally clear but the results are not clear.
lol...If this pendulum works how they say it works. You should be able to get in a helicopter in Charlotte NC. Lift off the ground for 3 hrs and land in California.
No, not true. The atmosphere moves with the Earth, and the helicopter moves with the air. Plus it has the same inertia as the Earth does. It doesn't just stop because it lifts off of the ground.
***** So the only thing that doesn't move with the atmosphere is a pendulum that hangs from a special fulcrum? LOL

Unlearn and Relearn The pendulum isn't suspended by air, like the helicopter, so not a good comparison. If you put a Foucault pendulum at the North Pole and observed it from above the atmosphere, it would swing in one plane, with the Earth rotating under it. For an observer on Earth, the pendulum's angle of swing appears to rotate throughout the day. The effect of the atmosphere rotating once per day would be negligible. Comparing that to a helicopter that hovers within the atmosphere is ridiculous. The helicopter will move with the atmosphere since it has the same momentum as the Earth and the atmosphere moves with the Earth. Your first comment suggested that a hovering helicopter will for some reason not move with the Earth or the atmosphere, but stay in one place. If you take a model helicopter on a train and hover it, it would still move with the train, since it has the momentum of the train and the air inside moves with it. Get it?
My3dviews Ah, I see...lol I just went to your page. Goodbye I ignore all Trolls!
holy shit get some sleep
Biggest fucault pendulem I've seen was at the science builing at BYU.
Worked as a cool clock, all day, all night.😮
With its electromagnetic motor
@@Heracles_FE The video you are commenting on does not have a motor.
Ooops, you done phock up AGAIN.
Fire isn't only more interesting, it is almost essential as the start of the pendulum must be absolutely as smooth as possible for the experiment to work. Any disturbance in the start and you're swing may not be entirely linear (a slight oval instead) and that throws off the experiment. You can also easily tell northern or southern hemisphere by visiting the restroom and flushing a toilet and observing the direction of the Coriolis effect.
I remember Easter Sunday weekend 1974, a buddy and I rented a car in Newport News whee we were attending the transportation school at Ft Euistis, VA, visited the Smithsonian and they had a Pendulum hanging from the big open space, it was knocking over domino size blocks with each swing. This was the old original Smithsonian, before the Air and Space Museum was built.
