Very interesting, excellent, and helpful video! Thank you. So anyways I found this vid because I've been puzzling over why most of the possible results are not observed. Particularly I was pondering how when you drop two balls do you see two balls rebound on the other side? Why not one with twice the velocity? I was confused because before this all I had been told was that alone conservation of kinetic energy and momentum explained the whole game.... But your explanation of discrete collisions seems like a much better model. I wonder if you could solder the first two balls into one object that should ensure the collision happens just once and there would be one ball flying out the other side with twice the velocity right?

This demonstration ignores the part that potential energy plays in Newton's Cradle. It is transformed to kinetic energy based on a formula that calculus can explain. Important thing here is energy is converted from one state to another based on position, motion, gravity, etc.

If i double the mass of the ball, just the one more to the right, and release, i will not have two balls coming out in the other side? One hit one ball?
@jsytac2 жыл бұрын
Following on from that hypothesis, if the first ball had twice the mass (same diameter), then there shouldn't be two balls moving at the far end as there is only one collision, meaning that the end ball would move off at twice the velocity that the first (double mass) ball moved in with. I'd love to see this tested. Maybe the @SloMoGuys could do something on this?
@Qwertype315 Жыл бұрын
I think thats mostly wrong. What travels through the balls is a compression wave with an intensity and duration. If you had two balls welded together, you would get two balls at the end. If you had a double mass ball made of uranium, same volume. Then the last ball would be catapulted twice as fast
@jayanththerokr8 жыл бұрын
Hi when you swung two balls in the opposite direction I could not understand the phenomenon . Shouldnt the momentum from both the balls cancel each other or as i assume since it is a elastic colllision the momentum is continuously transferred back to the swung balls instead of cancelling each other

@franktalbot41022 жыл бұрын
Thank you for this great explanation. I had never understood how the balls at the ends knew whether 1 ball or 2 balls were hitting. Now I know. But I do have a question. What if the 2 balls making the hit were welded together (or was one ball with twice the mass). My first thought was that one ball would move at twice the speed. This would conserve momentum mv. However, to conserve kinetic energy, 1/2mv^2, the last ball would have to move at 1.41 the speed. My thought therefore is that more then one ball would need to move at different speeds such that both both the momentum and kinetic energy would be conserved. Do you agree and would you be able to perform this experiment?

Thejus Mahajan well, if you doubled the mass of he first ball (I’m assuming that’s what you mean) then one ball on the end would be released at roughly twice the velocity because there is only one collision, but momentum needs to be conserved and because the mass of each of the balls stays constant, he only that can change is the velocity of the ball.

I use a video of this to explain why the official 9/11 report is a lie. 22 falling floors can only displace 22 floors, not the whole building. In order to use the energy from 22 falling floors to collapse the whole building it is necessary to weaken the structure by severing the upright support girders.
