Physics Videos by Eugene Khutoryansky You're one of the best teachers I've had in physics, but somethings been boggling my mind for a while and this video is a perfect opportunity to ask. Could you please explain how the smaller object when colliding with the bigger one(2.25) does not stop. I know in real life it would bounce off but according to Newton's laws of motion it shouldn't. According to Newton's third law, there should be an equal and opposite reactionary force on the smaller ball when it applies a force on the bigger ball and since force is equal to the change of momentum, when the bigger ball applies the equal and opposite force, the smaller ball should stop as the force it exerts is equal to it's momentum. This doesn't happen in real life. Something that may help you that I've thought of, is from a different example. Consider the smaller ball now stationary, and the bigger ball is moving toward it at a constant velocity. Same situation but the roles switched. When the bigger ball hits the smaller ball, I used to think the bigger ball should stop as the smaller ball produces an equal and opposite force to stop it. But then I realised that the bigger ball does not have to exert its full momentum onto the smaller ball, but only enough so that the move at a similar speed. So the momentum of the larger ball only decreases by a smaller amount as it takes less force to get the smaller ball moving at the same speed. That's my reasoning, unfortunately it does not explain what I mentioned earlier. My reasoning lead me to think that the smaller ball has to exert a larger force than its momentum can give to the larger ball, but it then gets cancelled out when the larger ball exerting the same amount of extra force to the smaller ball making it move in the opposite direction. However the reasoning mentioned in the last paragraph alludes to there being a conservation of velocity which definitely sounds untrue. I hope you read and understand my long winded messy post and give some kind of solution based on what you can understand of what I am saying, I hope I'm not wasting your time, sorry :)

Thank you very much for this video! I have a question, is there a way to know why the angular momentum is at 90°? (Momentum that is apparently to the right of the object, assuming that the direction to which the object moves is the "front"). Edit: I have no idea, but if I had to guess, I'd say it's like the "residual force" from the axis, which would make the orbits to slowly lose force.

question..... if the ball rotating around an axis has a certain linear momentum, by changing its distance from the center, the linear velocity has to be changed (in order to keep angular momentum constant) which means that the kinetic energy is changed without any external energy source and it seems to be violation of energy conservation. than how can that be possible ...please explain it @Eugene

To change the ball's distance from the center, a force is applied, thereby adding or removing energy from the system. The energy is being transferred to or away the source of the force.

When the particles repel each other while rotating ,they spin slower to keep the angular momentum constant. But how do we prove that the angular momentum of the universe is always constant during any interaction?
@EugeneKhutoryansky8 жыл бұрын
+Ibrahim Chahrour, this is a consequence of Newton's Laws of motion. Since for every force, there is an equal and opposite force, and F = mA, the net consequence is that momentum and angular momentum must be conserved. We also know this through experiment, in that we have always found momentum and angular momentum to be conserved for every experiment we conducted.

@EugeneKhutoryansky8 жыл бұрын
+isb pk, the units for angular momentum is "kg*m^2/s". This is different than the units for momentum in that we have meters^2 in the equation, due to the fact that we are also multiplying by the distance between the point and the object. You can calculate the angular momentum by calculating the area of the parallelogram I showed in the video. This can be done by taking the cross product of the two vectors that made up this rectangle. This can also be done by multiplying the length of the two arrows by each other, and then multiplying this number by the sine of the angle between them.

You are understanding is incorrect. Please to refer to F=ma . let m1 be the smaller ball and m2 be the bigger ball and also let's assume m1= 1kg and m2= 10kg . then after collision between the balls it is abvious the smaller ball will bounce back with greater acceleration that the bigger ball. In this case, by the equation f=ma , we can safely say that it's acceleration (lets assume m1 acceleration be a1 and m2 acceleration be a2) wil be in the ratio 10:1 so as to show f=m1.a1 = m2.a2.

How is this arbitrary point related to these two particles? Didn't understand that part. Do they exert force on this point?

+Max Webster, it is any point that we pick in space. No, this point does not exert a force on the particle. It is just that for any point we pick in space, the angular momentum around that point, as described here, will remain constant.

it is interesting that it is momentum which is constant instead of mass
