Energy and bouncing objects

  1. Jul 3, 2015 #1
    Hi,
    I want to make sure what is going to happen if I release ball to fall in an isolated container where no sound or heat is a production of collision. Would it keep going up and down without any change in height reached every single time ? what if I release a Newtonian liquid ? would it bounce too ? giving that liquid cannot transfer energy to ground , does this condition of isolated ground make no sense ??

    The container cannot prevent the ball from heating up during the collision.
    Same as above, you cannot prevent it from heating up.

    Energy is conserved. Perpetual motion machines do not exist. Using those principles, can you answer your own questions?

    By the way, discussion of perpetual motion is forbidden on PF.

    My own question is already answered in post #2

    All I did talk about was conservation of energy. I don't know if it's forbidden or even why, if so I didn't know before posting, thanks for telling me
