A simple energy question that needs answering.

  1. Nov 30, 2003 #1
    Explain what is happening to energy when a rubber ball is dropped and bounces.

    What does the ball eventually stop bouncing?

    Can anybody help me with this question?

    the potential energy of the ball is being changed into kinetic, and it loses energy when it hits the floor every time. i think thats right?

    With a perfectly elastic ball in a vacuum, it would bounce for ever:

    gravitational PE <--> kinetic energy <--> spring (deformed elastic ball) PE

    (PE = potential energy)

    In reality, energy is lost in (at least) three ways: air resistance losses, sound energy, and heat energy when the ball is deformed.
