It's a presumption 😆 you literally do not account for, "coriolis" or, "curvature" you literally only calculate the firing velocity, the weight of the projectile, and the distance to said target. You people are just indoctrinated.
Well done. But I knew a friend who used the Coriolis effect effect in his job! He was employed to calculate trajectories for ICBM's. Yep he was a targeteer for intercontinental missiles. Heavy math and physics at play. In shooting, unless I was to go to about a mile from a fixed position, a still, nearly wind less day would I take it into consideration, about a click.But many ballistic calculators offer this option. So many other things effect precision to a much higher degree to consider.
Question for anyone with experience: When shooting extreme long range, or firing artillery etc, does this actually come into the equation? I’d imagine you have to give it some consideration at times, but is it something that’s always accounted for when targeting, or is it insignificant enough compared to wind/humidity/temperature that it’s not something you worry about? When shooting over several kilometres for example, would you make adjustments based on Coriolis effect regardless of other environmental conditions, or would you just make your shot based on environmental conditions and then adjust from there?
You may find this interesting. Found it quite a while ago and haven't fully watched it again now, but naval gunnery is about halfway through. ruclips.net/video/wKTvZ8azi5U/видео.html
There is a story about this during the war in the Falkland Islands. The British Navy was missing wildly left because their shooting tables were all set up for the northern hemisphere.

@utmag You don't understand Inertial frame of reference. The reason airplanes and bullets don't do this is because they are already traveling the speed of the earth's rotation before they even start moving through the air. They aren't going to suddenly lose all their momentum when the go into the air. You also don't understand what the coriolis effect is either.
At the equator Earth is spinning counter clockwise at around 1039 MPH, so at the *45 Lat. the rotation is around 520 MPH which is equivalent 750 fps. Let us say all the following scenario targets are placed at 1000 yrds. Can you shoot to the north, impact the target then shoot south and impact the target without much windage adjustment? I ask because when you shoot north the Earth's rotation is coming from right to left but when you shoot south the rotation is from left to right. Can you shoot to the east, make impact then shoot west, make impact with out a whole lot of elevation adjustment? I ask because shooting east the Earth's rotation is coming towards you, when you shoot west the earths rotation is going away. What about diagonal directions NW, SE, then NE,SW, how much windage and elevation adjustment do you make? I ask as these diagonal directions NW, SE and then NW,SE are completely opposite. One last question, What formula do you use to figure in for the coriolis effect? Just a lot of critical thinking here. thank you for the uploads and in advance thank you for answering my book of questions. be well my friend.
Your question proves why it is not real. You could have no distance records if you could just shoot with the spin or against it. Each caliber has an effective distance. Notice it doesn't have the distance for each direction accounting for earth spin because it doesn't matter. If you shot against the spin you would get at least an extra QUARTER MILE out of a round in flight for one second. Pro golfers have drive hang times of many seconds. How come they aren't having to account? How about sky divers? RUclips Jerry Miculek 1000 yard 9mm shot. All military artillery uses azimuth projections, triangulation, based upon a flat surface reference point. Just saying...
So if I'm shooting straight east or west, I would think the coriolis effect wouldn't even come in play. I'm thinking if I'm shooting more north or south it would, with the earth spinning at 1,050 mph.
@James Earl We do not move, we do not rotate, we do not spin. The earth is flat and stationary. The Bible explains it! Read the Bible! God explains how He created the earth! If we believe in our heart and confess with our mouth that Jesus died on the cross for our sins and that God raised Him from the dead we are saved!
@James Earl Wouldn't planes be travelling around 1500 mph when going east to west and -500 mph west to east? They say no because of the atmosphere, so why does this not apply to ballistics?
@@wordup897 Bible is proof. You want me to give you an example? No problem bro. On a "picture of the earth" by nasa the clouds were photoshopped to form the letters XES. And if we go to the greek translation of the Bible we can see that XES is the number of the devil. Now we can have more proof. Just jump, you land at the same place, if you say atmosphere moves too then you contradict yourself cause you claim coriolis effect too. Oh... and please take a picture of the curvature, the math kinda doesn't apply to what we see from the plane bro.
@@jaysongilbertson101 Its funny how Coriolis effect doesnt apply to aircraft travel. N to S youd have to keep rolling L ro R to land, traveling W would take way less time than traveling from W to E. Just brain washed from sudo science.
@@JH-hx2cl No, that's now how it works. That is typical Flerfdom fallacy logic. .000694 rpm is Earth's rotation. That is very, very slow.

There are other effects that take place when flying that require for more correction than the very slight Coriolis effect.
Absolutely. It's more about the time of flight than the distance though. I find it easier to think about it at night: you aim at a star directly above you and fire. The bullet travels toward that star for, say a minute, and then starts falling again for a minute, but after 2 minutes that star is not directly above you, it's above a spot 2/60x15° West of you (consult your map for who you're aiming at 😁), but on the flip side is the fact that you have 2 minutes of wind drift to consider (which is almost always going to be a much bigger factor, except on the calmest of days!) , which is going to counter, maybe even move the bullet east of you in that two minutes. Coriolis is only a very small part of the problem, only to be considered when all the other problems have been dealt with.
@@glennvandenberg3912 Maybe during Korea or Vietnam, but It's a function of lat/long and direction of fire, which today is entered in the computer before the first shot is fired, so it's not like they're holding on a shot while private square eyes is doing the math on paper, but it is certainly part of the fire solution.
Hey I’m curious how this works. I’m getting into long distance shooting. Does this mean the earth is literally spinning underneath the bullet so we have to account for it?
It doesn't, you will never absolutely never account for, "Coriolis effect" NEVER, only the weight of your projectile, wind speed, and distance to target.
@@SuperMoshady I wouldn't put it that way: you are taking it into account, the same way you take the effect of gravity, wind (one mile per hour wind has about the same effect as Coriolis), temperature, humidity, mirage, etc into account. You take all factors that you can into account, adjust your sight or scope, and then you aim your sight or scope at the target: very very rarely is your barrel actually pointed in exactly the same direction that your sights are pointed, but I wouldn't say that you aren't aiming. Rather that's precisely what aiming is is taking all variables into account to make the shot! The nice thing about Gravity, Coriolis (and Eötvös) is that they don't change, they are ALWAYS predictable. Variables like Wind on the other hand, just between you and the target, can be from three different directions, creating 3 different mirages! Coriolis might be a very small effect, but to me it's an easy one to check off the list!
@@SuperMoshady No, it always spins at 1/4 MOA per second, at the poles and at the equator. For the calculations you use SINE and COSINE T=Time of Flight (in seconds) L=Latitude (in decimal degrees) D=Direction of Fire (in degrees) SIN(L) * T * 1/4MOA = horizontal adjustment in MOA SIN(D) * COS(L) * T * 1/4MOA = vertical adjustment in MOA (Negative means you are low and need to come up, positive means you are high and need to go down)
What do you mean by "second order effect"? I assume you mean "not that import", things like spin drift, maybe density alt., with "first order effect" meaning "more important", things like drop, and wind. Is this a correct understanding of the way you use the terms? If this is correct, could you lay out what you consider to be first order effects and what you consider to be second order effects? Thanks.
He makes a few mistakes trying to explain something he doesn't under-stand. That's not a hit on him just a fact of the matter. Coriolis has nothing to do with shooting nor ballistics. It is an APPARENT, which means not real but looks real as in the illusion of, curve of an object that is in fact traveling in a straight line. If, The rock is always spinning it would always be a very very important factor that must be taken into account at all ranges and all situations. The target is going to move while the bullet is flying. You must account for this. This can be accounted for with math because the rock only spins one way and at a perfect constant velocity. Now we need to know EXACTLY where you are on the spinning rock AND EXACTLY where the target is located on the spinning rock as it is a sphere and the velocity changes as you move away from the equator. This is because the circle of linear rotation is smaller thus not 1000MPH. Once you know that and have figured the earth's linear velocity at your location on the sphere and that of the target to get the difference so you know the hold over number you look at which direction you are shooting as opposed to the direction of the spin. Facing North west or facing south east will change the equation as the aforementioned linear velocity at that point will change because it is a sphere. Shooting perfectly east or west will not effect left to right but now distance. Shooting against the spin should result in a much further range of the bullet as it and the earth travel in opposing directions. With the spin will result in a shorter range as the earth runs with the bullet causing it to fall short. Perfectly north and south shots would have exact opposite equations not counting geographic location difference and linear velocity of the sphere. Every single time you changed compass directions it would change the factors needed to account for the always moving constant speed of the exact spot on rock the target is sitting on. You would have to get all of those things correct before you even began to account for the physical variables such as wind, temp, altitude... In other words, nobody uses this. Pull up "the king of two miles" competition and watch those guys shoot. Do they seen to be doing a multi faceted trig problem between shots?
@@beenschmokin I think RUclips attached your response as a reply to my thread by mistake. My question/thread is about what he considers first order effects and second order effects. I not only understand Coriolis (and Eötvös: many people mistake Eötvös for the vertical component of Coriolis: It is not, but rather ADDED to the vertical component of Coriolis) but am currently working on a video to explain it (and yes this video was the last trigger, though Ryan Cleckner's book was what got the idea started). Your response is entirely correct, but my personal opinion is that a text explanation is the wrong way to explain Coriolis and Eötvös: it can be a confusing concept to explain in word only. A picture's worth a thousand words, and an animation is worth a thousand pictures, which is why I'm going to make that video. I've got my animations done, just trying to simplify the script, make it more linear, so I'm not going in a thousand directions at once. Take care.
@@beenschmokin Also, he didn't say anything wrong, everything he said was correct, it's just that in trying to keep it simple there's nothing helpful there: again the problem of trying to do it with only words.
@@wilfdarr he says it only effects significantly long flight times. Wrong. He says it equals to about a click. Wrong. There is no universal click. He says it only matters in pristine solutions. Wrong. If the rock your target is sitting on is moving then this is the number 1 thing you would account for and must be accounted for at all distance and all calibers period the end. Ever been bird hunting? If when the bird flies out of the grass you are moving you would NEVER hit it. If I hold the target in my hand and run holding it what order effect would you call that? It's the same thing. Bang! Target is target is moving now. Lol lol lol lol! At the equator the earth "spins" at ~1000MPH at sea level. A day is 24hours and one spin so that's where you get that. Math it out and it's 1425ft per second. OK. So, if I fire a rifle due south at the equator and my bullet flight time is exactly 1 second I must account for the target moving 1425ft to the side. That's a quarter mile of hold over. As you move north or south this changes because the spin is less than 1000MPH but is still such a significant number it's a physical impossibility. Hitting a moving object with a moving object while firing from a moving object... The Coriolis effect is not a physical change but an illusory one. Kids on a merry go round. One sits across from the other. You turn the merry go and one kid throws the ball straight to the other kid. From where you are standing it will APPEAR to curve but in fact will not. A camera positioned above will show the ball goes straight. This is Coriolis. Bullets do not do magic stuff. NFL kickoff? Ball golf drives? Helicopters? Sky divers? Also, animations are not reality. Shooting a gun is real. Hitting a golf ball is real. Animations is how NASA causes people to think the magic rock spins under you. Physical reality cares not for belief.
So you do not need to think about it if you are trying to hit a target? If the bullet was spinning out from path 8 inches, you could miss the slender target you are trying to hit. Also has there been documentation of Coriolis under these "pristine" conditions? I have heard, and not found myself, any long range, indoor, firing range. To isolate Coriolis. The earth is not a spinning globe, it is flat and enclosed. We live in a time where we have communications technology, and so our words can travel at light speed, faster than bullets even. We could communicate through any problems.
So if the Coriolis has an effect on target why then can you just hover in a helicopter and get where your goin? And shouldn't you always think about seeing as how the earth is always spinning?
Yes but the problem is the Coriolis is not real, NO MATTER IN WHAT DIRECTION YOU SHOOT, you always have to aim a bit above the target if it's a long range shot because the bullet drops! *Not to mention that if Coriolis (if earth was really spinning) then we should calculate the Coriolis effect when we shoot north to south or south to north by aiming to the right or to the left on the target.* Not to mention how hard it will be for football, basketball, golf players to score, pass, shoot. What you said about the helicopter is correct! The thing is, that doesn't happen because the earth is flat and it is not rotating! If I just drop a dumbbell from 20 meters it mustn't land below when I dropped it but to the left or right or whatever. The earth is flat and stationary! Read the Bible and you will understand everything!

Gravity is only pulling down, if an object isnt attached to the earth in any shape, way, or form, the earth will be spinning beneath it. Think about it, the bullet is no longer attached to the earth so the earth will rotate under it.

It would have to apply. At the equator the earth spins at ~1000MPH at sea level. That's 1,425ft per second that the earth is moving while the bullet is in the air. As you move up or down in latitude you need to do a trig problem to figure out the lateral velocity of the earth at the point in which you stand, that point relative to the point at which your target is sitting and the compass direction. A bullet flight time of one second at the equator must account for the target moving 1425ft to one side. That's a quarter mile of hold over. RUclips right now Jerry Miculek 1000 yard 9mm shot. The ground ain't moving boys and girls.
Set up a pendulum to swing for hours, and you will see that it deviates owing to the direction of the rotation of the earth. This is an old physics experiment.
Then you're applying it wrong. It's just physics. CE is very very very small part of the equation, but it's a calculable part of the equation, so why (after you've fried all the bigger fish of course) would you refuse to consider it?
@@wilfdarr But who is shooting 1000m in wind-free conditions? It really sounds like it's only important for artillery. What is one click in terms of moa? He says only at 1000m could it possibly amount to as much as one click.
There is only spin drift. The bullet is spinning not the ground. Watch pro golf. Ball hang time is many seconds so the earth should have moved many many feet but it doesn't...

@@SDGlock23 it’s a very small effect my guy, given the group size of the rifle and the adjustments for wind and everything else it doesn’t really matter on a man sized target
@@bedlams9594 There are a number of things that can effect a bullet significantly at long distance, causing it to deviate. Supposed earth spin isn't one of them
Coriolis effect is an apparent deviation, not an actual deviation. If the earth moves the target slightly during the flight time of the bullet, then it moves under anything suspended in the air. This is a huge problem because you could simply hover in the air and as long as your location is west of you, it would come to you and yet, that will never happen. I know enough about shooting that at long ranges there are many things that can cause a bullet to deviate, earth "spin" isn't one of them.
No. A flat earther will just say it's BS. In order to get anything from the book you have to be working on the premise that the math is correct and the earth is in fact round. My suggestion well be: If you have a big lake (7 miles across or bigger, so you can't see one side from the other) near by, get them on a boat and have them watch buildings disappear and reappear over the horizon: if the world were flat they'd see the first floor along with the entire building disappear into a tiny dot as it gets further and further away, but you don't! You see the first floor disappear over the horizon, and then the second, and third, etc. If no big lakes near by, charter a small plane and get the pilot to climb out away from the city: even though the city is getting further away, you see more and more country behind you because of the angle. If this doesn't do it, well like they say, you can't fix stupid. And honestly, some people just pretend to be this stupid for the attention.
Coriolis challenge. Try standing in front of a North-South sniper shot at a mile or so ... trust your "effect" and see if the bullet misses left or right when directly targeted in the crosshairs... LOL The Earth is Stationary. Enjoy being fooled? Enjoy your Globe Earth Theory!
Coriolis of earth doesn’t exist , it would always apply if it was real. If you were in the equator the average movement would be around 460meters a second. Now if you had to shoot at a target 1000meters away you would defiantly see this effect take place. It never does take place as you know its just wind, velocity and attitude.

Have to agree with you. This guy makes the point that Coriolis too small to affect a bullet. Too many other forces are much more dominant such as friction, temperature, wind velocity, gravity, spin drift.
@@cadenmerritt6785 The coriolis effect cannot be induced in a lab, therefore it is nothing more than a hypothesis. Demonstrations at the equator are tourist traps using cheap tricks.
@@cadenmerritt6785 Why wouldn't planes be travelling around 1500 mph when going east to west at the equator and -500 mph west to east? They say no because of the atmosphere, so why does this not apply to ballistics?
To have coriolis effect you need 2 frames of reference. An inertial and non inertial reference frame. It is a visual effect. If you were on a round about and threw up a ball from the non inertial reference frame into the inertial reference frame, it would appear to drift as you spin beneath it. So if the earth was spinning a 1000 mph at the equator from east to west, than a flight from North Carolina to LA should take an hour and a half, but it doesnt, it takes 5 hours. And in most cases is a faster means of travel in the opposite direction. The coriolis effect is real, just not earth based. And if you come back with effing hurricanes, you have no idea what the hell you are talking about. Those are actual spin directions l. The coriolis is a not actual drift, it only appears to drift because you are rotating beneath...
You're explanation is correct and the reason the earth doesn't move under a helicopter or a soccer ball is because it's not moving. The effect states all objects. It doesn't say bullets. It says all. They measure NFL kickoffs in hang time as well as distance. Seconds pass by whilst this OBJECT is not attached to the earth but the earth does not spin from under it. It is not a thing. It is a appearance of something that is in fact not happening. It is the illusion of curvature not the proof of it.
Except it does: let's say you kick a 50yd kickoff, it hangs for 4 seconds: earth rotates 1/4 moa per second, that means the field moved 1moa while the ball was up. 1moa at 100 yds is 1.04in: 50 yds is 1/2 of 100 yds, ergo, the field moved 0.502 inch (just a hair over half an inch) while the ball was up. It's not much, but it's not nothing either.
@@wilfdarr Your use of MOA is very out of place and nonsensical. Do you measure how far you drive in a car in MOA? Or time? The hand on the clock moved **** MOA so it's 3:00. Lose the MOA shooting jargon. Time. Distance. Your math is absolutely wrong. We do not measure anything except shooting in MOA and it is not fixed unit of measurement.
My father was a sniper in Vietnam, he said NO SNIPER ever takes earth spin into account with long distance shots..I grew up in North Idaho..no hunter EVER takes earth spin into account when taking shots..Globies claim bullets shot from a rifle have "coriolis effect" and that military snipers need to take the earths spinning movement into account when taking long distance shots...I guess no one told these ding dongs that all rifles have spiral grooves cut on the inside so that the bullet doesnt tumble in flight, if these grooves are cut to the right, the bullet will travel to the right..cut to the left? travel to the left. It's called SPIN DRIFT.. kinda like a curve ball thrown by a baseball pitcher. So if this Cornholio Effect is real, wouldn't you need different calculations for North East South and West? Each degree on a compass would need a different calculation? What about shooting with the 1000mph Earth spin as opposed to against the Earth spin!?! The cornholio effect falls apart under the smallest of scrutiny
When you hunt are you over a kilometer away? He did say in the video that the effect depends on your latitude and direction of the shot, so you are correct that "you need different calculations for North East South and West. Each degree on a compass would need a different calculation."

@@jtgdyt2 Apparently you are the one who does not understand physics. Look up the true definition to the Coriolis effect from the man, Coriolis, who put it in books. It clearly states that ALL objects not attached to the earth will succumb to this and also that the effect is optical and not a physical change. The distance traveled is 100% IRRELEVANT the variable is a function of TIME. How long was the object in the air not how far it went. The earth is supposedly moving under any object not attached to it. The problem arises when a helicopter can hover and they say well that's the engine and the pilot is making it stay in one place. OK, so how about a golf ball? Pro golfers hang the ball up there for longer than a bullet but they don't have to account for the hole moving when they drive. NFL kickoff? How could you ever have any distance record if where you stood and direction you threw made all difference? Wouldn't all long range shots shoot perfectly against the spin at the equator to maximize distance? Now you haven't even considered that it's a sphere and a 25,000 mile sphere has a drop of 8inches per mile squared. 8*(mile^2power) Spherical geometry. Physics you were talking about. Meaning at 1 mile the horizon dropped 8inches, 2 miles: 32inches and at 10 miles: 800inches of drop. When you see a boat leave the horizon pull out binos and there it is again. Watch it go over the curve and pull out a spotting scope and there it is. Watch it disappear and pull out a telescope and there it is. Physics and math on paper are not always the same thing. Math on paper does not equal reality until you make it happen. Long distance objects are triangulated using an azimuth equation which relies on a flat plane of reference. RUclips "king of two miles" it's a long range shooting competition.
@@beenschmokin No need for me to point out your lack of knowledge of physics. You've done that yourself. Your "8 inches/mile" reference alone (which is wrong) makes you sound like a flat earth moron.
He said it is an APPARENT effect which we should disregard anyway. Which means there is NONE such. Apart from seeming to be there is patently NOTHING. Only false i.e. apparent NONEFFECT. Nicely said. Thanks a lot for this… nonlecture on… nothing at all. And g'bye. Unsubscribing this nonchannel on the spot. Efficiently, not apparently.
The spin of the earth has nothing to do with that . Because the bullet is spinning with the earth the earth does not spin under the bullet. When you jump up in the air do you hit the wall because the earth is spinning .
@@briankerr4512 It's about the angular momentum being different at different positions in relation to each other: Say your standing on the equator looking east at a target: The sun is rising in the east compared to the target (except that the sun doesn't actually move right, it's an illusion, the target is dropping so the sun just looks like it's rising) , so compared to you, the target is dropping, and the opposite if you're looking west of course, the target is rising. Imagine looking through your scope at the rising sun (don't actually, you'll go blind!) behind a target 3 miles away: you shoot at the sun directly behind your target, but at 3 miles your shot will take what, 10-15 seconds to get there, and in 15 seconds the sun will have moved (if you've ever watched a sunrise you realize how fast the sun is moving) and you'll be high of the target. Same when the sun is disappearing at the end of the day, in those 15 seconds, the sun goes from center of target below the horizon and you miss the target low. Now say you are standing on the north pole shooting south, sun goes around at 15° per hour (365°/24 hours), or 15moa/minute: again say the shot takes 15 seconds to reach its target, that's 3.75moa that your target has moved to the left (Sun is moving to the right) since you took your shot. At high latitudes it's (1moa=~1"/100', one mile =~5000', 3 miles) [EDIT}~16 feet (screwed up my yards and feet the first time, exaggerating the error by a factor of 3: not intentional {END EDIT] give or take. Now obviously these are extreme examples and in the continental Untied States you're not going to face either of these extreme scenarios, being neither near the north pole, nor on the equator, but I hope you can see he's not just BSing you either, it's a real thing, just not so important as some people think.
@@wilfdarr Very nice explanation, just a correction the issue when shooting north to south or vice versa is that your projectile and the target are moving at different speeds. For ex if you're at the north pole and the target is south of you, because the earth is a sphere the spin is faster at lower latitudes than it is at higher latitudes until you reach the equator then it's the opposite. The projectile and the target thus spin at different speeds causing the impact to hit right if you're in the northern hemisphere or left in the southern hemisphere.
@@Sorel366 Yes that is correct. But in my defense I did say "standing on the north pole" which I assumed the reader would understand to be stopped, shooting south, the target moves to the left (that of course is a different speed; the difference gets less and less as you go south until you and your target are equidistant from the equator at which time both you and the target are spinning at the same speed). I don't think it's a "correction" so much as "further explanation" as to why the opposite is true when shooting AT the North Pole vs FROM the north pole, which I'll admit I should have covered the whole "shooting at a stationary target from a moving vehicle" issue. ;-) The reason I wouldn't refer to the "projectile and the target spin at different speeds" when I'm talking of these things is because people are likely to get this confused with "spin drift", which of course is a completely different phenomenon.

It's a presumption 😆 you literally do not account for, "coriolis" or, "curvature" you literally only calculate the firing velocity, the weight of the projectile, and the distance to said target. You people are just indoctrinated.
The reason Vasily Zaitsev hit him in the right eye instead of the left at 1200 meters.
very interesting, relevant and informative. thank you for sharing.
Well done. But I knew a friend who used the Coriolis effect effect in his job! He was employed to calculate trajectories for ICBM's. Yep he was a targeteer for intercontinental missiles. Heavy math and physics at play. In shooting, unless I was to go to about a mile from a fixed position, a still, nearly wind less day would I take it into consideration, about a click.But many ballistic calculators offer this option. So many other things effect precision to a much higher degree to consider.
Question for anyone with experience:
When shooting extreme long range, or firing artillery etc, does this actually come into the equation?
I’d imagine you have to give it some consideration at times, but is it something that’s always accounted for when targeting, or is it insignificant enough compared to wind/humidity/temperature that it’s not something you worry about?
When shooting over several kilometres for example, would you make adjustments based on Coriolis effect regardless of other environmental conditions, or would you just make your shot based on environmental conditions and then adjust from there?
Really like the technical presentation.
The videos are not longer "private" and I can watch them? Cool....
I would imagine that naval gunnery would have to take this into account when firing at targets many miles away.
You may find this interesting. Found it quite a while ago and haven't fully watched it again now, but naval gunnery is about halfway through. ruclips.net/video/wKTvZ8azi5U/видео.html
There is a story about this during the war in the Falkland Islands. The British Navy was missing wildly left because their shooting tables were all set up for the northern hemisphere.
Crazy. I never thought of the planet moving.
But the earth is flat!!.what is this so call coriolis effect!!??? I'm calling shenanigans!!!.
It's a loaf of Bologna.
...The entire atmosphere and weather systems move with Earth's rotation. The atmosphere is friction-coupled to Earth's surface and angular momentum is transmitted to the atmosphere.
...When you go straight up in a helicopter, you and the helicopter are moving with the air mass.
...When you are traveling in an airplane at 500 mph, you and the air mass inside the plane are all moving at the same constant or near constant velocity. Toss a ball up in the air inside the moving plane, it will drop back down to you. The ball is not going to slam against the back of the plane.

...a basketball sized Globe with a .000694 RPM would result in 0.1028 foot per hour tangential velocity. Or 0.000019470 miles per hour.
While Earth's 1035 mph tangential velocity seems fast compared to humans microscopic sized endeavors, it isn't compared to the size of Earth. That's why all motion is relative.

Just here to share this with flat earthers/ coriolis deniers
@Mike Honcho ok bud don't really get what ur trying to get at but sure
I'm a flat earther. Came here to comment
@@SDGlock23 Danm u a dumn one then
@utmag You don't understand Inertial frame of reference. The reason airplanes and bullets don't do this is because they are already traveling the speed of the earth's rotation before they even start moving through the air. They aren't going to suddenly lose all their momentum when the go into the air. You also don't understand what the coriolis effect is either.
At the equator Earth is spinning counter clockwise at around 1039 MPH, so at the *45 Lat. the rotation is around 520 MPH which is equivalent 750 fps. Let us say all the following scenario targets are placed at 1000 yrds. Can you shoot to the north, impact the target then shoot south and impact the target without much windage adjustment? I ask because when you shoot north the Earth's rotation is coming from right to left but when you shoot south the rotation is from left to right. Can you shoot to the east, make impact then shoot west, make impact with out a whole lot of elevation adjustment? I ask because shooting east the Earth's rotation is coming towards you, when you shoot west the earths rotation is going away. What about diagonal directions NW, SE, then NE,SW, how much windage and elevation adjustment do you make? I ask as these diagonal directions NW, SE and then NW,SE are completely opposite. One last question, What formula do you use to figure in for the coriolis effect? Just a lot of critical thinking here. thank you for the uploads and in advance thank you for answering my book of questions. be well my friend.

@@jaysongilbertson101 oh u mean spin drift
Your question proves why it is not real. You could have no distance records if you could just shoot with the spin or against it. Each caliber has an effective distance. Notice it doesn't have the distance for each direction accounting for earth spin because it doesn't matter. If you shot against the spin you would get at least an extra QUARTER MILE out of a round in flight for one second. Pro golfers have drive hang times of many seconds. How come they aren't having to account? How about sky divers? RUclips Jerry Miculek 1000 yard 9mm shot.

@@beenschmokin My point EXACTLY Thank U
Earth is obviously stationery lads
So if I'm shooting straight east or west, I would think the coriolis effect wouldn't even come in play. I'm thinking if I'm shooting more north or south it would, with the earth spinning at 1,050 mph.
@James Earl We do not move, we do not rotate, we do not spin. The earth is flat and stationary. The Bible explains it! Read the Bible! God explains how He created the earth!

@@JH-hx2cl No, that's now how it works. That is typical Flerfdom fallacy logic.

...If you hover in a helicopter, the helicopter is moving with the atmosphere. You are NOT going to hover in the helicopter and expect to have another city come land under your helicopter.
...Moving several hundred mph in an airplane. The airplane, the air inside the plane, and any other objects are all traveling at the same velocity. You toss a ball in the air, inside the airplane, it's not going to slam the back of the airplane. It will drop right back down to your position.

There are other effects that take place when flying that require for more correction than the very slight Coriolis effect.
@@FieldCrew have you ever been in an army as a "physicist"?
@@JH-hx2clIt’s funny how you so obviously don’t know what you’re talking about.
So do naval guns or artillery or mortar crews firing over miles have to adjust for this effect?
Don't know but I don't think a 125mm round blowing a 15m wide hole in the ground matters to much if its a few metres one way or the other.
Absolutely. It's more about the time of flight than the distance though. I find it easier to think about it at night: you aim at a star directly above you and fire. The bullet travels toward that star for, say a minute, and then starts falling again for a minute, but after 2 minutes that star is not directly above you, it's above a spot 2/60x15° West of you (consult your map for who you're aiming at 😁), but on the flip side is the fact that you have 2 minutes of wind drift to consider (which is almost always going to be a much bigger factor, except on the calmest of days!) , which is going to counter, maybe even move the bullet east of you in that two minutes.
Coriolis is only a very small part of the problem, only to be considered when all the other problems have been dealt with.
@@glennvandenberg3912 It matters if the fire mission is called in danger close, then every meter matters.
I'm guessing that if its danger close the time of calculating and adjusting is a more important factor than it landing a metre or two either way.
@@glennvandenberg3912 Maybe during Korea or Vietnam, but It's a function of lat/long and direction of fire, which today is entered in the computer before the first shot is fired, so it's not like they're holding on a shot while private square eyes is doing the math on paper, but it is certainly part of the fire solution.
Beautifully explained and actually going into the other numerous variables. Well done!
Hey I’m curious how this works. I’m getting into long distance shooting. Does this mean the earth is literally spinning underneath the bullet so we have to account for it?
It doesn't, you will never absolutely never account for, "Coriolis effect" NEVER, only the weight of your projectile, wind speed, and distance to target.
If you think about it often enough in active circumstances in different geographic areas you get to know how to adjust without thinking about it.😅
Bryan litz is so practical, love the bergers
Just here for the baller comments..
Seems like coriolis doesn't matter too much
It does and it doesn't. It's a matter of a few feet over a couple miles, if that puts in in context.
@@wilfdarr so, you basically don't aim for what you are shooting at?
@@SuperMoshady I wouldn't put it that way: you are taking it into account, the same way you take the effect of gravity, wind (one mile per hour wind has about the same effect as Coriolis), temperature, humidity, mirage, etc into account. You take all factors that you can into account, adjust your sight or scope, and then you aim your sight or scope at the target: very very rarely is your barrel actually pointed in exactly the same direction that your sights are pointed, but I wouldn't say that you aren't aiming. Rather that's precisely what aiming is is taking all variables into account to make the shot! The nice thing about Gravity, Coriolis (and Eötvös) is that they don't change, they are ALWAYS predictable. Variables like Wind on the other hand, just between you and the target, can be from three different directions, creating 3 different mirages!
Coriolis might be a very small effect, but to me it's an easy one to check off the list!
@@wilfdarr doesn't the earth spin at different speeds depending on your location and direction? How exactly do you calculate for earth spinning?
@@SuperMoshady
No, it always spins at 1/4 MOA per second, at the poles and at the equator.
For the calculations you use SINE and COSINE
T=Time of Flight (in seconds)
L=Latitude (in decimal degrees)
D=Direction of Fire (in degrees)
SIN(L) * T * 1/4MOA = horizontal adjustment in MOA
SIN(D) * COS(L) * T * 1/4MOA = vertical adjustment in MOA
(Negative means you are low and need to come up, positive means you are high and need to go down)
What do you mean by "second order effect"? I assume you mean "not that import", things like spin drift, maybe density alt., with "first order effect" meaning "more important", things like drop, and wind.
Is this a correct understanding of the way you use the terms? If this is correct, could you lay out what you consider to be first order effects and what you consider to be second order effects? Thanks.
I would assume that first-order effects would be things like propellant type and barrel length, even shooting angle
He makes a few mistakes trying to explain something he doesn't under-stand. That's not a hit on him just a fact of the matter. Coriolis has nothing to do with shooting nor ballistics. It is an APPARENT, which means not real but looks real as in the illusion of, curve of an object that is in fact traveling in a straight line. If, The rock is always spinning it would always be a very very important factor that must be taken into account at all ranges and all situations. The target is going to move while the bullet is flying. You must account for this. This can be accounted for with math because the rock only spins one way and at a perfect constant velocity. Now we need to know EXACTLY where you are on the spinning rock AND EXACTLY where the target is located on the spinning rock as it is a sphere and the velocity changes as you move away from the equator. This is because the circle of linear rotation is smaller thus not 1000MPH. Once you know that and have figured the earth's linear velocity at your location on the sphere and that of the target to get the difference so you know the hold over number you look at which direction you are shooting as opposed to the direction of the spin. Facing North west or facing south east will change the equation as the aforementioned linear velocity at that point will change because it is a sphere. Shooting perfectly east or west will not effect left to right but now distance. Shooting against the spin should result in a much further range of the bullet as it and the earth travel in opposing directions. With the spin will result in a shorter range as the earth runs with the bullet causing it to fall short. Perfectly north and south shots would have exact opposite equations not counting geographic location difference and linear velocity of the sphere. Every single time you changed compass directions it would change the factors needed to account for the always moving constant speed of the exact spot on rock the target is sitting on. You would have to get all of those things correct before you even began to account for the physical variables such as wind, temp, altitude... In other words, nobody uses this. Pull up "the king of two miles" competition and watch those guys shoot. Do they seen to be doing a multi faceted trig problem between shots?
@@beenschmokin I think RUclips attached your response as a reply to my thread by mistake. My question/thread is about what he considers first order effects and second order effects.
I not only understand Coriolis (and Eötvös: many people mistake Eötvös for the vertical component of Coriolis: It is not, but rather ADDED to the vertical component of Coriolis) but am currently working on a video to explain it (and yes this video was the last trigger, though Ryan Cleckner's book was what got the idea started).
Your response is entirely correct, but my personal opinion is that a text explanation is the wrong way to explain Coriolis and Eötvös: it can be a confusing concept to explain in word only. A picture's worth a thousand words, and an animation is worth a thousand pictures, which is why I'm going to make that video. I've got my animations done, just trying to simplify the script, make it more linear, so I'm not going in a thousand directions at once.
Take care.
@@beenschmokin Also, he didn't say anything wrong, everything he said was correct, it's just that in trying to keep it simple there's nothing helpful there: again the problem of trying to do it with only words.
@@wilfdarr he says it only effects significantly long flight times. Wrong. He says it equals to about a click. Wrong. There is no universal click. He says it only matters in pristine solutions. Wrong. If the rock your target is sitting on is moving then this is the number 1 thing you would account for and must be accounted for at all distance and all calibers period the end. Ever been bird hunting? If when the bird flies out of the grass you are moving you would NEVER hit it. If I hold the target in my hand and run holding it what order effect would you call that? It's the same thing. Bang! Target is target is moving now. Lol lol lol lol! At the equator the earth "spins" at ~1000MPH at sea level. A day is 24hours and one spin so that's where you get that. Math it out and it's 1425ft per second. OK. So, if I fire a rifle due south at the equator and my bullet flight time is exactly 1 second I must account for the target moving 1425ft to the side. That's a quarter mile of hold over. As you move north or south this changes because the spin is less than 1000MPH but is still such a significant number it's a physical impossibility. Hitting a moving object with a moving object while firing from a moving object... The Coriolis effect is not a physical change but an illusory one. Kids on a merry go round. One sits across from the other. You turn the merry go and one kid throws the ball straight to the other kid. From where you are standing it will APPEAR to curve but in fact will not. A camera positioned above will show the ball goes straight. This is Coriolis. Bullets do not do magic stuff. NFL kickoff? Ball golf drives? Helicopters? Sky divers? Also, animations are not reality. Shooting a gun is real. Hitting a golf ball is real. Animations is how NASA causes people to think the magic rock spins under you. Physical reality cares not for belief.
The earth is a non-inertial frame. It sounded like you said inertial.
So you do not need to think about it if you are trying to hit a target? If the bullet was spinning out from path 8 inches, you could miss the slender target you are trying to hit. Also has there been documentation of Coriolis under these "pristine" conditions? I have heard, and not found myself, any long range, indoor, firing range. To isolate Coriolis. The earth is not a spinning globe, it is flat and enclosed. We live in a time where we have communications technology, and so our words can travel at light speed, faster than bullets even. We could communicate through any problems.
Why do some of your videos get listed as private and blocked .
So if the Coriolis has an effect on target why then can you just hover in a helicopter and get where your goin? And shouldn't you always think about seeing as how the earth is always spinning?
Yes but the problem is the Coriolis is not real, NO MATTER IN WHAT DIRECTION YOU SHOOT, you always have to aim a bit above the target if it's a long range shot because the bullet drops! *Not to mention that if Coriolis (if earth was really spinning) then we should calculate the Coriolis effect when we shoot north to south or south to north by aiming to the right or to the left on the target.* Not to mention how hard it will be for football, basketball, golf players to score, pass, shoot. What you said about the helicopter is correct! The thing is, that doesn't happen because the earth is flat and it is not rotating! If I just drop a dumbbell from 20 meters it mustn't land below when I dropped it but to the left or right or whatever. The earth is flat and stationary! Read the Bible and you will understand everything!

I don't understand how the bullet has the force to leave the earth's gravitational force distance; it doesn't leave the atmosphere.
Gravity is only pulling down, if an object isnt attached to the earth in any shape, way, or form, the earth will be spinning beneath it. Think about it, the bullet is no longer attached to the earth so the earth will rotate under it.

Ok
basically if you’re a normal human with a rifle this doesn’t apply
It would have to apply. At the equator the earth spins at ~1000MPH at sea level. That's 1,425ft per second that the earth is moving while the bullet is in the air. As you move up or down in latitude you need to do a trig problem to figure out the lateral velocity of the earth at the point in which you stand, that point relative to the point at which your target is sitting and the compass direction. A bullet flight time of one second at the equator must account for the target moving 1425ft to one side. That's a quarter mile of hold over. RUclips right now Jerry Miculek 1000 yard 9mm shot.

It really does
Set up a pendulum to swing for hours, and you will see that it deviates owing to the direction of the rotation of the earth. This is an old physics experiment.
It's attached to the ground... facepalm!
You can’t control the swing of a pendulum from a single point. It keeps swinging the same direction, but the Earth rotates under it.

@@wilfdarr But who is shooting 1000m in wind-free conditions? It really sounds like it's only important for artillery. What is one click in terms of moa? He says only at 1000m could it possibly amount to as much as one click.
With the Coriolis Effect you have to figure in Spin drift.
There is only spin drift. The bullet is spinning not the ground. Watch pro golf. Ball hang time is many seconds so the earth should have moved many many feet but it doesn't...
LOL At what distance at what part of the supposed globe and in which direction ( and with what weapon) can I line you up in my sights and I will have to miss my kill shot due do this myth?
ruclips.net/video/jX7dcl_ERNs/видео.html&ab_channel=Gunwerks. This video shows the Eötvös Effect and what it does to a bullet. Their labeling is incorrect because coriolis effect applies to north and south shooting and that will cause drift left and right. East and west shooting will cause drift up and down.
Coriolis effect is only in the books it's never in real life

@@Acepilot235 Kevin Malone, The Office
There are snipers who admit they never factor in earth rotation, there's no need to since it doesn't rotate.
@@SDGlock23 it’s a very small effect my guy, given the group size of the rifle and the adjustments for wind and everything else it doesn’t really matter on a man sized target
@@bedlams9594 There are a number of things that can effect a bullet significantly at long distance, causing it to deviate. Supposed earth spin isn't one of them
Coriolis effect is an apparent deviation, not an actual deviation. If the earth moves the target slightly during the flight time of the bullet, then it moves under anything suspended in the air. This is a huge problem because you could simply hover in the air and as long as your location is west of you, it would come to you and yet, that will never happen. I know enough about shooting that at long ranges there are many things that can cause a bullet to deviate, earth "spin" isn't one of them.
These people are indoctrinated.
would you recommend this book to a flat earther?
No. A flat earther will just say it's BS. In order to get anything from the book you have to be working on the premise that the math is correct and the earth is in fact round.
My suggestion well be:
If you have a big lake (7 miles across or bigger, so you can't see one side from the other) near by, get them on a boat and have them watch buildings disappear and reappear over the horizon: if the world were flat they'd see the first floor along with the entire building disappear into a tiny dot as it gets further and further away, but you don't! You see the first floor disappear over the horizon, and then the second, and third, etc.
If no big lakes near by, charter a small plane and get the pilot to climb out away from the city: even though the city is getting further away, you see more and more country behind you because of the angle.
If this doesn't do it, well like they say, you can't fix stupid. And honestly, some people just pretend to be this stupid for the attention.
I'm sorry.. look people there are many variables that are considered while shooting. Coriolis effect isn't one of them
It is
Coriolis challenge. Try standing in front of a North-South sniper shot at a mile or so ... trust your "effect" and see if the bullet misses left or right when directly targeted in the crosshairs... LOL The Earth is Stationary. Enjoy being fooled? Enjoy your Globe Earth Theory!
Coriolis of earth doesn’t exist , it would always apply if it was real. If you were in the equator the average movement would be around 460meters a second. Now if you had to shoot at a target 1000meters away you would defiantly see this effect take place. It never does take place as you know its just wind, velocity and attitude.
Can you explain this a bit more please?
@@janbernad4729 Coriolis effect is not real. Magnus effect is. Hopefully that helps.
@@jaysongilbertson101 Coriolis effect is just as real as the Magnus effect, however it works differently from what you described
@@jaysongilbertson101
...The entire atmosphere and weather systems move with Earth's rotation. The atmosphere is friction-coupled to Earth's surface and angular momentum is transmitted to the atmosphere.
...When you go straight up in a helicopter, you and the helicopter are moving with the air mass.
...When you are traveling in an airplane at 500 mph, you and the air mass inside the plane are all moving at the same constant or near constant velocity. Toss a ball up in the air inside the moving plane, it will drop back down to you. The ball is not going to slam against the back of the plane.
.
Merry-go-round Coriolis videos are misleading. Globe animations on videos are misleading. The RPM is jacked up way, way, way, way too high.
...The Earth is only rotating at .000694 RPM. Twice as slow as a clock hour hand.
...If you were able to view Earth from a stationary observation position in space, it would take 1 hour just to view a 15° angle change of a continent's land position.
...Take a basketball and rotate it once in 24 hours, relatively slow I would say.
...Centrifugal force would become a serious issue if the Earth was spinning like a basketball on a player's finger.
...Take a large Globe with a circumference of a 29.5 inch basketball.
...a basketball sized Globe with a .000694 RPM would result in 0.1028 foot per hour tangential velocity. Or 0.000019470 miles per hour.
While Earth's 1035 mph tangential velocity seems fast compared to humans microscopic sized endeavors, it isn't compared to the size of Earth. That's why all motion is relative.
----------------------
Now about Coriolis. It is a very minimal effect because of Earth's very, very slow .000694 RPM.
...Coriolis is about different Tangential Velocities at different latitudes, Inertia and Angular Momentum.
...Launching an object from the Equator 0° Lat toward 45° Latitude. The object started at a Latitude where the Tangential Velocity was 1035 mph and moving towards Latitude that is steadily decreasing to a Tangential Velocity of 734 mph.
Coriolis most certainly has an impact on Hurricanes. It imparts the opposite spin on the hurricane.
'The Coriolis Effect Explained' on Atlas Pro youtube channel has an excellent video explaining and animation showing how the change of tangential velocities at different latitudes affects objects.
An apparent (that is, not real) drift. Next?
Put this myth to rest: have a long range competition where you account for Coriolis and your flat earth opponent does not. That would be a highly watched event and sponsors would make bank. Do it.
It has already been done by less experienced shooters that forget to take the coriolis effect into account, and they always miss. So yeah, the Earth is a sphere no matter how much you cry about it
Show me actual manuals that use this. Not just what "could happen"
This is a spin doctor. So Suttle it's not used in just about anything other than rockets going to space

Bla Bla Bla, buy my book, Bla Bla Bla.
Great explanation..........now explain a howitzer round that can shoot 10 miles.........I’ll help you.......we don’t take it to account. It’s a bunch of shit!
Have to agree with you. This guy makes the point that Coriolis too small to affect a bullet. Too many other forces are much more dominant such as friction, temperature, wind velocity, gravity, spin drift.
@@dsbranch9144 Do you have any knowledge of extreme long range shooting? Because if you don't account fir coriolis, you'll surely miss.
Earth is flat and stationary. That's why there's no perceptible coriolis effect.
Why do hurricanes spin?
@@cadenmerritt6785 The coriolis effect cannot be induced in a lab, therefore it is nothing more than a hypothesis. Demonstrations at the equator are tourist traps using cheap tricks.
@@stephenbradley445 Ok but why do hurricanes spin?
@@cadenmerritt6785 Why wouldn't planes be travelling around 1500 mph when going east to west at the equator and -500 mph west to east? They say no because of the atmosphere, so why does this not apply to ballistics?
@@wordup897 sure but why do hurricanes spin?
To have coriolis effect you need 2 frames of reference. An inertial and non inertial reference frame. It is a visual effect. If you were on a round about and threw up a ball from the non inertial reference frame into the inertial reference frame, it would appear to drift as you spin beneath it. So if the earth was spinning a 1000 mph at the equator from east to west, than a flight from North Carolina to LA should take an hour and a half, but it doesnt, it takes 5 hours. And in most cases is a faster means of travel in the opposite direction. The coriolis effect is real, just not earth based. And if you come back with effing hurricanes, you have no idea what the hell you are talking about. Those are actual spin directions l. The coriolis is a not actual drift, it only appears to drift because you are rotating beneath...
@RUclips Censoring lol whenever you need it mane.
You're explanation is correct and the reason the earth doesn't move under a helicopter or a soccer ball is because it's not moving. The effect states all objects. It doesn't say bullets. It says all. They measure NFL kickoffs in hang time as well as distance. Seconds pass by whilst this OBJECT is not attached to the earth but the earth does not spin from under it. It is not a thing. It is a appearance of something that is in fact not happening. It is the illusion of curvature not the proof of it.
Except it does: let's say you kick a 50yd kickoff, it hangs for 4 seconds: earth rotates 1/4 moa per second, that means the field moved 1moa while the ball was up. 1moa at 100 yds is 1.04in: 50 yds is 1/2 of 100 yds, ergo, the field moved 0.502 inch (just a hair over half an inch) while the ball was up. It's not much, but it's not nothing either.
@@wilfdarr what about the blimp in the air filming the game from above. How far should that move? 😆😆😆
@@wilfdarr Your use of MOA is very out of place and nonsensical. Do you measure how far you drive in a car in MOA? Or time? The hand on the clock moved **** MOA so it's 3:00. Lose the MOA shooting jargon. Time. Distance. Your math is absolutely wrong. We do not measure anything except shooting in MOA and it is not fixed unit of measurement.
My father was a sniper in Vietnam, he said NO SNIPER ever takes earth spin into account with long distance shots..I grew up in North Idaho..no hunter EVER takes earth spin into account when taking shots..Globies claim bullets shot from a rifle have "coriolis effect" and that military snipers need to take the earths spinning movement into account when taking long distance shots...I guess no one told these ding dongs that all rifles have spiral grooves cut on the inside so that the bullet doesnt tumble in flight, if these grooves are cut to the right, the bullet will travel to the right..cut to the left? travel to the left. It's called SPIN DRIFT.. kinda like a curve ball thrown by a baseball pitcher. So if this Cornholio Effect is real, wouldn't you need different calculations for North East South and West? Each degree on a compass would need a different calculation? What about shooting with the 1000mph Earth spin as opposed to against the Earth spin!?! The cornholio effect falls apart under the smallest of scrutiny
When you hunt are you over a kilometer away?
He did say in the video that the effect depends on your latitude and direction of the shot, so you are correct that "you need different calculations for North East South and West. Each degree on a compass would need a different calculation."
@@bloogain Do you consider the entire body of science and physics to be bullshit?
Spot on brother. Read Hathcock's book. It's never used. RUclips right now "king of two miles." Mortar teams use spotters. Artillery uses laser targeting from recon units.
@@jtgdyt2 Apparently you are the one who does not understand physics. Look up the true definition to the Coriolis effect from the man, Coriolis, who put it in books. It clearly states that ALL objects not attached to the earth will succumb to this and also that the effect is optical and not a physical change. The distance traveled is 100% IRRELEVANT the variable is a function of TIME. How long was the object in the air not how far it went. The earth is supposedly moving under any object not attached to it. The problem arises when a helicopter can hover and they say well that's the engine and the pilot is making it stay in one place. OK, so how about a golf ball? Pro golfers hang the ball up there for longer than a bullet but they don't have to account for the hole moving when they drive. NFL kickoff? How could you ever have any distance record if where you stood and direction you threw made all difference? Wouldn't all long range shots shoot perfectly against the spin at the equator to maximize distance? Now you haven't even considered that it's a sphere and a 25,000 mile sphere has a drop of 8inches per mile squared. 8*(mile^2power) Spherical geometry. Physics you were talking about. Meaning at 1 mile the horizon dropped 8inches, 2 miles: 32inches and at 10 miles: 800inches of drop. When you see a boat leave the horizon pull out binos and there it is again. Watch it go over the curve and pull out a spotting scope and there it is. Watch it disappear and pull out a telescope and there it is. Physics and math on paper are not always the same thing. Math on paper does not equal reality until you make it happen. Long distance objects are triangulated using an azimuth equation which relies on a flat plane of reference. RUclips "king of two miles" it's a long range shooting competition.
@@beenschmokin No need for me to point out your lack of knowledge of physics. You've done that yourself. Your "8 inches/mile" reference alone (which is wrong) makes you sound like a flat earth moron.
This not true. This is called the magnus effect. It has nothing to do with the movement of the earth. Use science not fairy tails.
so how do they apply it effectively?
This is why I've learned to skip you videos. You really don't give useful information. Ever.
BS

Hahahahaha😂😂😂 clown show
Cope
He said it is an APPARENT effect which we should disregard anyway. Which means there is NONE such. Apart from seeming to be there is patently NOTHING. Only false i.e. apparent NONEFFECT. Nicely said. Thanks a lot for this… nonlecture on… nothing at all. And g'bye. Unsubscribing this nonchannel on the spot. Efficiently, not apparently.
The spin of the earth has nothing to do with that . Because the bullet is spinning with the earth the earth does not spin under the bullet. When you jump up in the air do you hit the wall because the earth is spinning .
You would move closer to it due to this effect, actually.
@@Pbairsoftman not a chance when I jump Im moving at the same rate as the planet is.
@@briankerr4512 It's about the angular momentum being different at different positions in relation to each other:
Say your standing on the equator looking east at a target:
The sun is rising in the east compared to the target (except that the sun doesn't actually move right, it's an illusion, the target is dropping so the sun just looks like it's rising) , so compared to you, the target is dropping, and the opposite if you're looking west of course, the target is rising. Imagine looking through your scope at the rising sun (don't actually, you'll go blind!) behind a target 3 miles away: you shoot at the sun directly behind your target, but at 3 miles your shot will take what, 10-15 seconds to get there, and in 15 seconds the sun will have moved (if you've ever watched a sunrise you realize how fast the sun is moving) and you'll be high of the target. Same when the sun is disappearing at the end of the day, in those 15 seconds, the sun goes from center of target below the horizon and you miss the target low.
Now say you are standing on the north pole shooting south, sun goes around at 15° per hour (365°/24 hours), or 15moa/minute: again say the shot takes 15 seconds to reach its target, that's 3.75moa that your target has moved to the left (Sun is moving to the right) since you took your shot. At high latitudes it's (1moa=~1"/100', one mile =~5000', 3 miles) [EDIT}~16 feet (screwed up my yards and feet the first time, exaggerating the error by a factor of 3: not intentional {END EDIT] give or take. Now obviously these are extreme examples and in the continental Untied States you're not going to face either of these extreme scenarios, being neither near the north pole, nor on the equator, but I hope you can see he's not just BSing you either, it's a real thing, just not so important as some people think.
@@wilfdarr Very nice explanation, just a correction the issue when shooting north to south or vice versa is that your projectile and the target are moving at different speeds. For ex if you're at the north pole and the target is south of you, because the earth is a sphere the spin is faster at lower latitudes than it is at higher latitudes until you reach the equator then it's the opposite. The projectile and the target thus spin at different speeds causing the impact to hit right if you're in the northern hemisphere or left in the southern hemisphere.
@@Sorel366 Yes that is correct. But in my defense I did say "standing on the north pole" which I assumed the reader would understand to be stopped, shooting south, the target moves to the left (that of course is a different speed; the difference gets less and less as you go south until you and your target are equidistant from the equator at which time both you and the target are spinning at the same speed). I don't think it's a "correction" so much as "further explanation" as to why the opposite is true when shooting AT the North Pole vs FROM the north pole, which I'll admit I should have covered the whole "shooting at a stationary target from a moving vehicle" issue. ;-)
The reason I wouldn't refer to the "projectile and the target spin at different speeds" when I'm talking of these things is because people are likely to get this confused with "spin drift", which of course is a completely different phenomenon.
Not worth listening to.
