A bouncy rubber ball is dropped from a height of about a metre above the ground .it falls to the ground, bounces and then rises back to almost the height from which it was dropped. Describe the main energy transformations that take place from the point at which the ball first touches the ground until the point it leaves the ground again.

answer
Gravitational potential energy is converted into kinetic energy and then into sound energy or (strain ,interna energy)
is that correct answer ,help plz

no. The question asked what happened to the energy as it hit the ground and slowed then moved up. Remember hooke's law?
