A tennis ball is dropped from a height onto a hard floor.
The ball bounces several times. Each bounce is lower than the one before. The ball then comes to rest on the floor.
Explain the energy changes from the moment the ball is dropped until it comes to rest.
Your answer should refer to the total energy of the system.
