I enjoy your videos on the whole, but this recent slant of the past few videos, explaining emergent phenomena through intuitive mechanical physics, has been particularly interesting. . Have you considered doing a video on non-polar intermolecular bonds? I think it fits in a similar category (although it must [I assume] specifically invoke electromagnetism). Polar bonds are easy to understand. They're like magnets, but with electric charge. But non-polar cohesion is more complicated. Or at least I assume it is, because I currently do not understand it. :-D
I just love this channel. After watching a video you really feel like you finally understand things a bit better compared to what they teach in schools.
I do love your videos, unfortunately this one fails to provide the central insight. The key moment occurs at 6:32 where the container shape changes but the pressure remains the same... unfortunately your arrows don't explain why this is true. Where are the vertical forces coming from on the right side, given that the container is a single rigid body and is thus not being pushed down onto the liquid molecules by gravity?
I didn't explain this with words, but I explained it with the pictures and animations, such as the animation of the spheres bouncing around inside three containers of three different shapes.
I also feel like there wasn't a good explanation. The visual example earlier in the video showed the phenomen in action but didn't 100% explain the intuition. The best explanation I have is Pascal's Law (IOW go watch more Physics Videos). For containers of the same height: If we assume the upper section behaves the same irrespective of shape, then it always exerts the same pressure on the bottommost slice. By Pascal's Law the pressure is equal across the bottommost slice. Because of this, if you extend the container by adding a new bottommost slice below the old one, then the pressure exerted on this new slice is the same regardless of where you connect it. Also note that any perceived gain in downward force (like the molecules in the "cave" at 6:37) come from the sides/ceilings of the container, and any perceived loss of downward force (like in a funnel shaped container) comes from the sides/floors of the container.
@@enriquegonzalez2802 (and iestyn) : Yeah, I got confused by that, too. Here's how I try to explain it to myself: Molecules are *_really_* tiny, and in a fluid, they have complete and unlimited freedom of movement. Up, down, sideways, slantways, etc. So any pressure applied to them from any direction will be spread out in all directions. Up, down, sideways, etc. So even in the "cave" part of the diagram, the fluid pressure is pressing on the walls -- and ceiling -- of the cave. (And of course, the cave walls are pushing back with equal pressure, or else they would burst outward.) Does that help?

Sir I will be very happy if you added the topic of bohr's model of hydrogen atom in your list of future videos . The main confusing fact is that according to classical mechanics how and why an electron continuously emitting electromagnetic waves should ultimately fall into the nucleus . Does classical physicists put this wrong postulate forward without considering that nucleus is positively charged? This (1:30 seconds) animation illustrates electromagnetic waves produced by an accelerating charged particle in terms of electric field only. I wonder if you represent this in terms of vector field of lorentz force (electrc force + magnetic force) . ruclips.net/video/oH7WRKglKNk/видео.html Larmour formula tells us how an accelerating charged particles emit electromagnetic waves. Abraham-Lorentz force is a recoil force on an accelerating charged particle causes by the partile emitting electromagnetic radiation. It is also called the radiation reaction force , radiation damping force or the self-force. Actually what is the reason behind moving of electrons in circular orbits without radiating energy continuously as light. Is there an electric potential space time analogous to gravitational potential space time . Please clear this confusion with intuitive visual and logical reasoning. Is it the proton in the centre which doesn't allow the electron to emit electromagnetic waves continuously. The orbital velocity of the innermost electons is maximun then why is it in lower energy state. Is there some kind of mysteries energy boxes attached to electrons which we can't see. I am still confused after I studied classical electrodynamics . Does the increase in energy of the electrons by absorbing a photon means an increase in tangential orbital velocity ? Now when the electrons fall into lower energy orbit then which acceleration here is the reason for production of electromagnetic wave (photon) ? What about larmour assumption and Abraham-Lorentz force ? I am super confused .
Amazing!! My thermodynamics teacher struggled a lot explaining us this effect, it would have helped so much to watch this video as an introduction 👍👍 Thank you for this greatly well made video!!
I love your videos. It makes me more curious about physics. Thank you so much for all videos. We support you. Keep it up. Since my professor presented your video in physics class, i visited your channel and watched many videos. I Love your channel
That's because of the normal reaction from the wall ...It is a scenario in a fluid so one layer of molecules are always in random motion.But here those set of molecules inside the small space are restricted to move upward,hence when they try to move up they can't because of the normal reaction of the wall,which is equivalent to having molecules occupy the place of the part of the wall
I think were missing some fundamental point of this video. I also don't get the boat one, i always thought it's because of surface area and not because of the athmosphere, does this mean a ship will not work on a planet with no athmosphere then?
@@JarutheDamaja The ship can displace a large amount of water because of its great surface area at the bottom. And no, a ship can still work in vacuum because the ship overall is less dense, as its hollow inside.
6:30- if you’re wondering why the balls experience a downward pressure, I think it’s because the vibrations of the nearby balls knock them in all directions which forces them against the ceiling box which is pushing them downward.
Every time I learn something new in a video by Eugene, somehow it always shows up later in my life in a meaningful way. Weirdly, it's not always related to physics. It's really interesting how that nearly always happens.
When I clicked I thought this was about the Archimedean Principle: That for all real numbers x and y with x > 0, there is a natural number n such that nx > y. The physics principle makes more sense, especially in the context of molecules and your channel name. Great video as always!
Physics makes so much sense but it's often difficult to get the concept out, these videos are like a Rosetta stone. Thanks Eugene, keep up the good work.
Your videos have done wonders for me while studying for the MCAT, but it's amazing how many concepts obey action-reaction as demonstrated by Newton's third law
There was an old trick in the 1800s that used this principle. A barrel would be filled to the brim with water, and would hold its shape just fine. Then they would insert a long tube at the top, and fill it with only a small amount of water, which greatly increases the pressure (as the height of the water has gone up drastically) and the barrel would burst.
Best video amoung all the videos about Archimedes principle on RUclips . That's how a good teacher should teach us. Eugene can you please manage to make a video on scalar triple product and vector triple product whose duration is 3-7 minutes . Well the reason for my request is the property and theorem of vector triple product which is somewhat like this a×b×c = (a.c)b -(a.b)c . This theorem is very important because it is also a step involved in deriving Kepler Laws of planatery motion. We are finding a lot of difficulty and can't visualize this theorem. You once made a very fantastic short duration video on dot product and cross product . So please make a video on scalar triple product and specially VECTOR TRIPLE PRODUCT in future. But please try to make this video faster as we are struck in our vector textbooks struggling to visualize this theorem.
There's a special type of pleasure when at the end of the video the object with twice the density finally sinks to the bottom and no other molecule is underneath it
Fantastic video! 2 critiques: 1. You don't explain why the change in the shape of container (6:32) doesn't change the pressure in this model. You do later show the lateral forces, but it is not explained in a video by this particular model. 2. At 9:10 you don't explain that the weight (I hope I am using the correct term) of an object with twice the density will be decreased by the same amount as the weight of the fluid it displaces. It would be cool if you did, especially using this model. Thanks for the video. If I have time later, I will translate to Polish. Very busy day today.
Thanks for the compliment. Regarding your first point, I don't explain it with words, but I explain it with the pictures and animations, such as the animation of the spheres bouncing around inside three containers of three different shapes. Regarding the second point, I don't state this, but it can be inferred from the statement made earlier about the net upward pressure on an object. Thanks again.
Actually the horizontal vectors were representing thermal vibrations. Did you see that the spheres on top were trying to evaporate and undergoing less collisions per second. But they were again pulled back by gravity . If these were air molecules of atomic gases present above the surface they would have evaporated the liquid with the passage of time .Some of the air (atmospheric gas) spheres would also have been entrapped in the empty spaces between liquid spheres . It tells us that if there was no air present on the surface of liquid the liqiud molecules will never go farther away from the surface of the liquid. In reply to your question in a video by Eugene titled " thermodynamics and the end of the universe " you can see that objects at higher elevations have hight gravitational potential energy and therefore create more motion as they fall and I loved the way sir Eugene presented this fact in this video by dropping totally static fluid into different containers. As these spheres will fall the energy boxes will be distributed evenly amoung all the spheres and all spheres gradually gain same mechanical energy (kinetic + potential energy content) (No energy boxes will be dissipated as heat and thereby there will be no sensation of heat in this animation). To understand the concept of kinetic energy see the video of sir Eugene on Bernoulli principle . Now i want to tell you that the fluid is not static as the molecules of the bottom are constantly colliding with each other in the horizontal direction and the walls of the container are balancing these forces. As the energy boxes are evenly distributed amoung all shperes the shperes at high attitude will have more gravitational potential energy boxes than kinetic energy boxes and the spheres at the bottom have more kinetic energy boxes than gravitational potential energy boxes and the pressure (from collisions of molecules with one another and with the walls of the container) is determined by kinetic energy boxes and has nothing to do with gravitational potential energy boxes. So the molecules at bottom (having more kinetic energy) have greater velocity (greater "horizontal" and vertical components of velocity) than the molecules at the top. It is actually kinetic molecular theory with the exception of including gravity in this case without including heat transfer. If there is no gravity and the container is closed then the pressure of the fluid will be same throughout. I hope if sir Eugene liked my reply. I am very happy that sir Eugene is making videos on fluid mechanics on my and many other people's request .
Face reveal videos and behind the scenes videos are sometimes popular with channels like these. It gives the channel a personal touch and helps people see all the time and effort that goes into making these videos.
@@EugeneKhutoryansky Cool. Thx for the reply. Maybe I’ll check it out. It was just a random thought. I think whenever people watch videos that don’t show any faces, human nature is inherently curious about who the people behind the vids. I figure I’m not the only one that’s curious about the genius that creates these things. At any rate, total respect. Oh, also, the reason I was thinking a face reveal or a behind the scenes vid may help is because when people see the person behind these creations, it creates a level of empathy and humanity for your hard work and may lead to more patreon supporters. Dunno, just a thought.
Dear Eugene Khutoryansky, can you please make a video on how you make these vidoes, what software you use and reccomendations. These videos are incredible. I simply cannot imagine how you simulated the density of particles here. Seems like a magic for me=)
@@EugeneKhutoryansky thank you for the reply. I just wanted to add that I think that you contribute immensely to the society with your amazing teaching. Thank you=)
Good video. I believe it should have a quick mention that the level of the liquid raises by the amount corresponding to the objects submerged (totally or in part) - the liquid is only displaced, not compressed, so it goes somewhere else, raising the level, even if only so slightly. Also, showing the liquid at molecular or atomic level and the objects at a much larger scale, with molecules / atoms not visible, is somewhat incorrect, although it does help to convey the image of what is going on. The most important part of the concept starts at 4:43 - the balance of forces determines floatability.
Jose Silveira Actually the horizontal vectors were representing thermal vibrations. Did you see that the spheres on top were trying to evaporate and undergoing less collisions per second.

Anything related to "ELECTROMAGNETIC THEORY" would be helpful. As an electronics engineering student this is one of the most difficult topics. Would be really helpful if this topic videos are possible
I already have many videos on that topic. For example, you may want to watch my video "Electromagnetism - Maxwell's Laws" at ruclips.net/video/9Tm2c6NJH4Y/видео.html
OK so there is still an upward bouoyancy force on the object that sinks to the bottom. But, where does this force come from if there is nothing but the ground below it?there are no molecules to push it up
Спасибо большое, Евгений, показываю ваши видео своей пятилетней дочери, она начинает о чем то догадываться) а что за программа для симуляции? Если не секрет
Did you mean "Hamiltonian Mechanics"? This is already on my list of topics for future videos. Also, I have now added to the list double pendulums, triple pendulums, etc. Thanks.
Physics Videos by Eugene Khutoryansky, I am sorry 😅 yes I mean Hamiltonian Mechanisms . Can you please animate the double, triple , quadruple and n-tuple pendulums with increasing and decreasing the distances between consecutive bobs i.e increasing or decreasing the sublengths of the string of pendulum . By sublengths I mean distance between two adjacent bobs. It will lead to a better visualization . 😘😘 I have watched your quantum mechanics playlist. It is very interesting 😍. In your video of Maxwell laws of electromagnetism you said that quantum electrodynamics is another story. Now you have a video on quantum choromodynamics but you haven't made a video on quantum electrodynamics. It will be good if you add topics of relativistic classical electrodynamics vs relativistic quantum electrodynamics is this video. 😍😍😍 Also make a video on how electromagnetic waves arw produced by acceleration (linear or circular motion) of charges . Moreover discuss the concepts of Lamour principle and Abraham Lorentz recoil radiation reaction force on accelerating charge particles and there is no visual for how the magnetic field of a changed particle will look like if it is both spinning and accelerating ~ in the direction of spin axis ~ in the direction perpendicular to spin axis . There is not a single image on google about this . I hope you will cover these topics in a beautiful way in future . 😘😘
When the shape of the container changed, then the pressure on the molecules underneath the added square actually experience a pressure in the x direction(against the wall) rather than the same pressure downwards
I think a connection can be drawn between Archimedes' principle and convection. In a container that contains just one type of fluid molecules (helium, for fun) a clump of molecules within that region that has a higher temperature will have a lower density than the the surrounding molecules. So convection is just an extension of buoyancy. If we really want to stretch an analogy to its limits, we could probably draw a connection between convection and the Brazil nut effect. If you take a can of mixed nuts and shake it for a while, without changing the orientation of the can, the larger nuts will tend to collect at the top while the smaller nuts find their way to the bottom, regardless of the density of those nuts. Of course, there are a lot more factors involved. Even when shaken to simulate Brownian motion, a bunch of solid objects packed loosely in a container does not behave quite like a liquid or a gas. We can easily picture, for example, how bits of sand would bias toward the bottom of a container of gravel, simply because there are spaces between the gravel where it can fit. So the collisions are more complex to describe, but it's an interesting principle.

But please try to make this video faster as we are struck in our vector textbooks struggling to visualize this theorem.
Yes do this fast.
Thanks, Qaseem. I will add that to my list of topics for future videos.
Excellent Eugene
Thanks. Glad you liked it.
Всё наглядно получилось. Как всегда выше всяких похвал!
Thanks for the video, Eugene! Great as always.
Thanks. Glad you liked it.
Flexing with that raytracing :D
Thank you for making these amazing and easy to understand videos. You definitely satisfy my wandering mind!! Keep it up!!
Thanks. I am glad you like my videos.
Thank you so much prof Eugene.
Nicely explained.
Thanks.
@@EugeneKhutoryansky does upthrust depend upon density of object ??And if then how.??
Can you make a video of your process preparing these lectures one day? Like a vlog? Love your channel
Maybe one day. Thanks.
There's a special type of pleasure when at the end of the video the object with twice the density finally sinks to the bottom and no other molecule is underneath it
Perfect explanation of Archimedes Principle. 👌👌#LoveofPhysics.
Thanks. Glad you liked my explanation.
Great as always. Thank You
Thanks.
Fantastic video! 2 critiques:
1. You don't explain why the change in the shape of container (6:32) doesn't change the pressure in this model. You do later show the lateral forces, but it is not explained in a video by this particular model.
2. At 9:10 you don't explain that the weight (I hope I am using the correct term) of an object with twice the density will be decreased by the same amount as the weight of the fluid it displaces. It would be cool if you did, especially using this model.
Thanks for the video. If I have time later, I will translate to Polish. Very busy day today.
Thanks for the compliment. Regarding your first point, I don't explain it with words, but I explain it with the pictures and animations, such as the animation of the spheres bouncing around inside three containers of three different shapes. Regarding the second point, I don't state this, but it can be inferred from the statement made earlier about the net upward pressure on an object. Thanks again.
Actually the horizontal vectors were representing thermal vibrations. Did you see that the spheres on top were trying to evaporate and undergoing less collisions per second. But they were again pulled back by gravity . If these were air molecules of atomic gases present above the surface they would have evaporated the liquid with the passage of time .Some of the air (atmospheric gas) spheres would also have been entrapped in the empty spaces between liquid spheres . It tells us that if there was no air present on the surface of liquid the liqiud molecules will never go farther away from the surface of the liquid. In reply to your question in a video by Eugene titled " thermodynamics and the end of the universe " you can see that objects at higher elevations have hight gravitational potential energy and therefore create more motion as they fall and I loved the way sir Eugene presented this fact in this video by dropping totally static fluid into different containers. As these spheres will fall the energy boxes will be distributed evenly amoung all the spheres and all spheres gradually gain same mechanical energy (kinetic + potential energy content) (No energy boxes will be dissipated as heat and thereby there will be no sensation of heat in this animation). To understand the concept of kinetic energy see the video of sir Eugene on Bernoulli principle . Now i want to tell you that the fluid is not static as the molecules of the bottom are constantly colliding with each other in the horizontal direction and the walls of the container are balancing these forces. As the energy boxes are evenly distributed amoung all shperes the shperes at high attitude will have more gravitational potential energy boxes than kinetic energy boxes and the spheres at the bottom have more kinetic energy boxes than gravitational potential energy boxes and the pressure (from collisions of molecules with one another and with the walls of the container) is determined by kinetic energy boxes and has nothing to do with gravitational potential energy boxes. So the molecules at bottom (having more kinetic energy) have greater velocity (greater "horizontal" and vertical components of velocity) than the molecules at the top. It is actually kinetic molecular theory with the exception of including gravity in this case without including heat transfer. If there is no gravity and the container is closed then the pressure of the fluid will be same throughout. I hope if sir Eugene liked my reply. I am very happy that sir Eugene is making videos on fluid mechanics on my and many other people's request .
Face reveal videos and behind the scenes videos are sometimes popular with channels like these. It gives the channel a personal touch and helps people see all the time and effort that goes into making these videos.
I don't think I will ever appear in person in any of the videos on this channel, but there is a video of me on my Facebook page. Thanks.
@@EugeneKhutoryansky
Cool. Thx for the reply. Maybe I’ll check it out. It was just a random thought. I think whenever people watch videos that don’t show any faces, human nature is inherently curious about who the people behind the vids. I figure I’m not the only one that’s curious about the genius that creates these things. At any rate, total respect. Oh, also, the reason I was thinking a face reveal or a behind the scenes vid may help is because when people see the person behind these creations, it creates a level of empathy and humanity for your hard work and may lead to more patreon supporters. Dunno, just a thought.
Ótimo vídeo!!! Parabéns !!! 🇧🇷🇧🇷🇧🇷
Unbelievably cool video!!
Thanks.
1:41 the dramatic piano music returns!
The video say all about makers hardwork.
Great work To clear concept.
Thanks for the compliment.
Dear Eugene Khutoryansky, can you please make a video on how you make these vidoes, what software you use and reccomendations. These videos are incredible. I simply cannot imagine how you simulated the density of particles here. Seems like a magic for me=)
Thanks for the compliments. I explain how I make my 3D animations in my video at ruclips.net/video/6Hl5dvA88Uo/видео.html
@@EugeneKhutoryansky thank you for the reply. I just wanted to add that I think that you contribute immensely to the society with your amazing teaching. Thank you=)
Good video. I believe it should have a quick mention that the level of the liquid raises by the amount corresponding to the objects submerged (totally or in part) - the liquid is only displaced, not compressed, so it goes somewhere else, raising the level, even if only so slightly. Also, showing the liquid at molecular or atomic level and the objects at a much larger scale, with molecules / atoms not visible, is somewhat incorrect, although it does help to convey the image of what is going on. The most important part of the concept starts at 4:43 - the balance of forces determines floatability.
Jose Silveira Actually the horizontal vectors were representing thermal vibrations. Did you see that the spheres on top were trying to evaporate and undergoing less collisions per second.

Now i want to tell you that the fluid is not static as the molecules of the bottom are constantly colliding with each other .
Anything related to "ELECTROMAGNETIC THEORY" would be helpful. As an electronics engineering student this is one of the most difficult topics.
Would be really helpful if this topic videos are possible
I already have many videos on that topic. For example, you may want to watch my video "Electromagnetism - Maxwell's Laws" at ruclips.net/video/9Tm2c6NJH4Y/видео.html
OK so there is still an upward bouoyancy force on the object that sinks to the bottom. But, where does this force come from if there is nothing but the ground below it?there are no molecules to push it up
Always wonderful work :)
Thanks.
I love how the confusion of years hot cleared up in really just some seconds
Hugs from Brazil.
I have nothing to comment, but I want more people to see this channel, so here I am :D
Спасибо большое, Евгений, показываю ваши видео своей пятилетней дочери, она начинает о чем то догадываться) а что за программа для симуляции? Если не секрет
Thanks. I make my 3D animations with "Poser." The simulations were made with an add-on purchased separately called "Poser Physics."
This stuff is amazing! great science with legit explanations and graphics
Thanks.
how are you so underrated?
because people are uninterested
Because people after watching forget about sharing his video
Some of their previous videos are so boring thatbI used them for sleeping, when I couldn't
Eugene , great work
Thanks for the compliment.
Thanks for a great view of physics with your eyes.
Thanks.
Sir please also make a videoon holtmaniam mechanics. Also make a video on double pendulums , triple pendulums a n-tuple pendulums .
Did you mean "Hamiltonian Mechanics"? This is already on my list of topics for future videos. Also, I have now added to the list double pendulums, triple pendulums, etc. Thanks.
Physics Videos by Eugene Khutoryansky, I am sorry 😅 yes I mean Hamiltonian Mechanisms . Can you please animate the double, triple , quadruple and n-tuple pendulums with increasing and decreasing the distances between consecutive bobs i.e increasing or decreasing the sublengths of the string of pendulum . By sublengths I mean distance between two adjacent bobs. It will lead to a better visualization . 😘😘
I have watched your quantum mechanics playlist. It is very interesting 😍. In your video of Maxwell laws of electromagnetism you said that quantum electrodynamics is another story. Now you have a video on quantum choromodynamics but you haven't made a video on quantum electrodynamics. It will be good if you add topics of relativistic classical electrodynamics vs relativistic quantum electrodynamics is this video. 😍😍😍 Also make a video on how electromagnetic waves arw produced by acceleration (linear or circular motion) of charges . Moreover discuss the concepts of Lamour principle and Abraham Lorentz recoil radiation reaction force on accelerating charge particles and there is no visual for how the magnetic field of a changed particle will look like if it is both spinning and accelerating
~ in the direction of spin axis
~ in the direction perpendicular to spin axis .
There is not a single image on google about this . I hope you will cover these topics in a beautiful way in future . 😘😘
If you ever doubted that 1% of the population provides 99% of the wisdom and inspiration to the world, behold Eugene !
Very nice explanation
Thank you Eugene!
You are welcome and thanks.
This simulation is amazing, thank you!
Glad you liked it. Thanks.
When the shape of the container changed, then the pressure on the molecules underneath the added square actually experience a pressure in the x direction(against the wall) rather than the same pressure downwards
They experience pressure in all directions, due to the fact that the molecules are vibrating and colliding in all directions.
So are you saying that the pressure is equal in all directions against the container because they are bouncing against each other ?
Yes.
I think a connection can be drawn between Archimedes' principle and convection. In a container that contains just one type of fluid molecules (helium, for fun) a clump of molecules within that region that has a higher temperature will have a lower density than the the surrounding molecules. So convection is just an extension of buoyancy.
If we really want to stretch an analogy to its limits, we could probably draw a connection between convection and the Brazil nut effect. If you take a can of mixed nuts and shake it for a while, without changing the orientation of the can, the larger nuts will tend to collect at the top while the smaller nuts find their way to the bottom, regardless of the density of those nuts. Of course, there are a lot more factors involved. Even when shaken to simulate Brownian motion, a bunch of solid objects packed loosely in a container does not behave quite like a liquid or a gas. We can easily picture, for example, how bits of sand would bias toward the bottom of a container of gravel, simply because there are spaces between the gravel where it can fit. So the collisions are more complex to describe, but it's an interesting principle.
Thanks, I wish I am able to watch all your videos
Thanks.
Great video, keep up the great work!
Super, entertaining and understandable...
Thanks.
Love these as always.
Thanks.
