!6:33 "Both the momentum and angular momentum of the entire universe as a whole is always constant." Newton's third law of motion states that when one object exerts a force on a second object, that second object exerts a force that is equal in magnitude and opposite in direction on the first object. That means vectors of momentum are always created in pairs of the same magnitude but in opposite directions. As a result the net momentum created is always equal to zero. Therefore, due to the Law of Conservation of Momentum and Newton's third law of motion, both the linear momentum and angular momentum of the entire universe as a whole must be equal to zero. That means the entire universe cannot have a net spin in any direction and cannot have a net linear motion in any direction. Nothing outside the universe can change the linear momentum and angular momentum of the entire universe from zero to another value because something that can change the momentum of any part of the universe must be part of the entire universe by definition and that something must also obey the Law of Conservation of Momentum and Newton's third law of motion.
These videos are like a super advanced alien race has decided to come and teach us the nature of reality, step by step, gently and nicely. Thank you :)
Hey Eugene, I would just like to say that you are a very talented person and for the effort that must go into making your videos you deserve a lot more views and subscribers.
I agree! I am astounded by the clarity of presentation, cleanliness of animation, and relatively low views/subs....Someone should help this channel reach the audience it deserves !!
In case, you have not already seen them, I also uploaded several other videos recently. As always, for each video that you like, you can help more people find it in their UA-cam search engine by clicking the like button, and writing a comment. Lots more videos are coming very soon. Thanks.
***** That's a wolf, not a dog. This is supposed to be a wolf, a fox, and a coyote. And thanks for the compliment on my videos. I am glad you like them.
*****, I didn't write the equation relating torque to force, but I showed the relationship graphically. I try to use as few equations as possible when explaining these concepts, just as was the case in my videos on Quantum Mechanics and Relativity.
Your videos are absolutely brilliant and totally necessary for the general public who can't all be scientists but really want to understand the concepts. I can get used to the terms of angular momentum and many others and still have time for other things and to think.
This helps me prepare for my physics class. Learning the basic concepts makes it easier to digest the lectures that are more in depth, and helps me put the math i do in context.

Physics Videos by Eugene Khutoryansky I don’t know how the translation editing on UA-cam works, but it would have been more appropriate if I was informed that there were some contextual mistakes in my translation so that I can review my translation and rectify what was wrong as it helps me learn from my mistakes because i’m a language learner in addition to being an engineer student. It so disappoints me that a person gets into my translation and alters what he/she sees as right 👎🏽.
TheAdel, I am sorry about this. The way that UA-cam subtitle editing works is that anyone can offer a submission, and then anyone can then offer modifications to that submission. The person who created the modifications did not know who the original submission was from, so he did not know how to contact you about this. I apologize that this happened to you.
I know you have already received much praise for your work over the years but I think we should still tell you the amazing work you’ve done. Your videos are incredibly helpful and “simplify” it but still talk about the math so we truly understand it. Thank you.
15:58 : In the absence of an external torque, the angular momentum of an object is always constant. Yes out in space, but here on mother earth we have something called gravity and there is some air resistance that will slow down the object that is rotating. The angular veloctity is time dependent, and will slow down due to the friction we have in the air. Nice videos, i have been struggling to understand the dynamics in class, but you have opened my eyes. Keep up the good work :-)
You are like a good model of a facilitator teacher who gives an easy-to-learn visualization of math and science . . thank you .. go ahead .. God bless you.
imagine if these videos were in virtual reality? That's a million dollar idea. You could start a khan academy with virtual reality animated tutorials and put every university out of business
What if the education system implement how the equation was derived and how it is physically or with a model and with vr you can do those stuff more realistically and it's more feasible. I think we need to be taught to experiment and come up with equations with experiments to really understand what the equation is with numbers and you can just use an algorithm to find the best number to fit the equation from other equations of the relevants to find unthinkable equations for more progress
Absolutely awesome! I like all the definitions you offered, which are all clear and no confuse to me. Moreover, you define what a terminology refers very carefully and step by step.
Honestly I love so much these animations and I feel lucky for finding this channel. This is one the best channels of animated physics; moreover its animations are _unique_ compared to other channels'!

I love your videos too much. In your videos not only a human learns Physics, but also every animal including frogs, tortoise, fox and even an intelligent owl also learn Physics. Hats off to you.
I have to say that i like the way passion and Eugene's video style mix together to create these videos, that makes physics not only understandable but enjoyable. As a future engineer and most important, as student i really appreciate your work, and i have to say you are clever! Grasp an abstract idea, understand it AND explain it in a way others can understand is key in education. Keep it doing. Greetings from Colombia 🇨🇴 :)

+Eugene Khutoryansky An interesting application combining the Universal Law of Rotation and Gravity was done by James Watt (1788) in his centrifugal governor. This device is also known as the "Fly Ball Governor" for steam engines. Personally, I found it to be an elegant method of early systems control. Although its original use is considered archaic, the principal is in modern day machines like CVT transmissions.
Really awesome video! Understood the concept of Moment of Inertia which I mugged up for exams! I really thank you for such great and informative videos which are helping lots of people for understanding concepts easily!😊
From Bangladesh, your video is amazing.... love the slowness especially!! But I think I have a bit more confusion about torque and Moment of Inertia. Do you have videos on these with the maths and interpretation of intution of the formulas?
XboxSkateVids, I already have a video on entropy. It is titled, "Thermodynamics and the End of the Universe." Though, I will soon also be coming out with a second video on entropy. And thanks for the compliment about my videos.
@@EugeneKhutoryansky my dream 😟😟 is to be scientist but no one will help me now I am 18 years old I thing I have to relate with these videos I have some my theories
Hey Eugene do you have a video tutorial on Lagrange points between planets and the stars they orbit? The spinning balls on a stick rotating made me think about the James Web Telescope out at L2, Thanks
Awesome video as always, you work with other science youtubers! Also could you please make a video explaining inertia? And the transmission among the slides of the video are kinda slow Keep it up I really enjoy your videos
For some reason, I was always under the impression that hitting something dead-on would apply more in terms of velocity, and that hitting the edge would apply more angular motion but less velocity. So no matter where you apply a force to an object, it's always the same? There's no trade-off?
Veritasium has an experiment on this. He shot a bullet vertically at a block that was free to ascend, both directed at its center, and off to the side. He discovered that the centers of both blocks would rise the same vertical height, just as conservation of linear momentum would predict. The block that was hit eccentrically did spin with more angular velocity, but they both received the same linear velocity as a consequence of the collision. Since the collisions were both inelastic, this means that more energy is dissipated in the center shot to the block than the eccentric shot, since the eccentric shot has to also provide the rotational kinetic energy.
Out of curiosity, it says that it's harder to change the rotation of an object if the mass is further away from the axis of rotation. So if the mass is further away from the axis of rotation then it has a further distance to travel to complete a full revolution? So does that mean that the "wheel" would actually technically move the same amount of distance when applying the same amount of force? For example if it took X amount of force to rotate a "wheel" one complete revolution, then if you increased the distance of the mass from the center of the axis to double it's original length, does that mean the "wheel" would rotate half of a revolution? though still technically traveling the same amount of distance being that the larger wheel now has twice the distance to travel to complete a full revolution?
Given two stationary wheels of equal mass (10 kg), which both can be modeled as uniform solid cylinders. Wheel 1 is 0.5 m in radius, and wheel 2 is 0.25 m in radius. Suppose wheel 2 is made from a material that is 4 times the density of wheel 1, to make this possible. We apply a 10 Newton-second impulse to both wheels at a position 0.25 m from the axis of rotation, in the tangential direction. Both wheels are initially at rest, but free to spin on a fixed axis. The resulting spin is that wheel 2 will spin four times as fast as wheel 1, after receiving the given impulse. Wheel 1 will spin at 1 radian/second from this impulse, and wheel 2 will spin at 4 radians/second. This is due to the fact that moment of inertia is proportional to radius squared.
Shirshak Bajgain Thanks for the compliment. I am glad that you liked the animations. As for the topic for my next several videos, I would like to leave this as a surprise. :)
i want to ask something. If i rotate an object in space, then the object will rotate continuously forever right?.... so, i think we can create a fake gravity using rotation on the space like the one i saw on "interstellar" movie. suppose we are on the edge of the object which is spinning, we will experience a gravity towards the outside. Then, based on the theory of relativity, we will see the clock in universe is moving slower than our clock, isn't it?
aghaanantyab Yes, the object will rotate forever, and yes, we can rotate a spaceship or a space station, thereby creating the appearance of a fake gravity towards the outside for the people on the inside wall rotating with the spaceship. However, this will not have the impact on the flow of time that real gravity has. For example, from the perspective of a person floating at the center of the spaceship, there is no apparent force of gravity present, and he would therefore see all the clocks in the Universe outside of the spaceship behave the same way as he would if the spaceship was not rotating.

I've always wondered... what software do you use to make the animations?
YellowKazooie, I make these animations with the software "Poser." Thanks.
Said, Total motion= motion of CG + Rotational motion. Is it linear displacement+Rotational displacement ?
Also does relativity apply on this? I mean if the outer edge spins faster than the ones inside does that mean that time is slower in the outer edge?
Does analysis of bending moment in concrete beams use the same concept that you showed here. I see similar concpets.
Hey Eugene do you have a video tutorial on Lagrange points between planets and the stars they orbit? The spinning balls on a stick rotating made me think about the James Web Telescope out at L2, Thanks

Given two stationary wheels of equal mass (10 kg), which both can be modeled as uniform solid cylinders. Wheel 1 is 0.5 m in radius, and wheel 2 is 0.25 m in radius. Suppose wheel 2 is made from a material that is 4 times the density of wheel 1, to make this possible. We apply a 10 Newton-second impulse to both wheels at a position 0.25 m from the axis of rotation, in the tangential direction. Both wheels are initially at rest, but free to spin on a fixed axis.
The resulting spin is that wheel 2 will spin four times as fast as wheel 1, after receiving the given impulse. Wheel 1 will spin at 1 radian/second from this impulse, and wheel 2 will spin at 4 radians/second. This is due to the fact that moment of inertia is proportional to radius squared.
This video is not only educational, but also somehow relaxing?
I am glad you enjoyed my video.
Thanks! Always a perfect job!
Thanks for the compliment.
Great informative video sir 👍 👍 👍 great work sir
Thanks for the compliment about my video. Glad you liked it.
nice :) Great animation . Now which videos are you going to make?
Shirshak Bajgain Thanks for the compliment. I am glad that you liked the animations. As for the topic for my next several videos, I would like to leave this as a surprise. :)
Eugene, is the voice a robot or your actual voice? That voice just fits in very well with the video
Simon Riley The narration for all my videos is done by Kira Vincent.
Very good video. Nice work
Thanks. Glad you liked my video.
very very very good explanation
i want to ask something.
If i rotate an object in space, then the object will rotate continuously forever right?.... so, i think we can create a fake gravity using rotation on the space like the one i saw on "interstellar" movie. suppose we are on the edge of the object which is spinning, we will experience a gravity towards the outside. Then, based on the theory of relativity, we will see the clock in universe is moving slower than our clock, isn't it?
aghaanantyab Yes, the object will rotate forever, and yes, we can rotate a spaceship or a space station, thereby creating the appearance of a fake gravity towards the outside for the people on the inside wall rotating with the spaceship. However, this will not have the impact on the flow of time that real gravity has. For example, from the perspective of a person floating at the center of the spaceship, there is no apparent force of gravity present, and he would therefore see all the clocks in the Universe outside of the spaceship behave the same way as he would if the spaceship was not rotating.
these videos are very helpful thank you.
Glad to hear that my videos are helpful. Thanks.
thank you , your content is very helpful.
I am glad my videos are helpful. Thanks.
Such great explanations
Thanks. I am glad you liked my explanations.
Great video . Anyone knows the background music please ?
All the music in this video is from the free UA-cam audio library, and the names of the songs are the following.
Morning_Mood_by_Grieg
Waltz_of_the_Flowers_by_Tchaikovsky
Mast
you are a genius
I like all your videos
Thanks for that really great compliment and I am glad that you like my videos.
these videos help me to visualize and not mug up formulas , thanks
I am glad that my videos are helpful. Thanks.
Great videos! What are the software tools you use for them?
I make my 3D animations with "Poser." Thanks.
Thanks!
Thank you. Great work!
Manoj Suresh Thanks for the compliment. Glad you liked the video.
I really love your videos....they are more than amazing.this makes physics really easy.😊:):D
Thanks for the compliment about my videos. I am glad you like them.
So theoretically if you have a lever long enough can you lift the universe?
Your Waifu Sucks there is no way a material can resist such weight
@@joaolisboa7775 The universe is in free fall, it is weightless.
What program did you use to ceare this fantasic animation
Nawwaf A Thanks for the compliment about the animations. I made them with the program "Poser." Thanks.
Thanks a lot man
Wish these videos were available when I was in college
I am glad you like my videos.
You should do some more videos regarding mathematics, particularly more concepts of calculus
These videos are amazing!
Thanks for the compliment about my videos.
Good explanation Eugene sir
Thanks. I am glad you liked my explanation.
