In a bouncing ball, what happens to kinetic energy during impact?

During impact the ball deforms as it compresses. The kinetic energy of the moving ball is transformed into elastic potential energy stored in that deformation. As the ball expands back to its shape, that stored energy is released again as kinetic energy, propelling the ball upward. In real balls, some energy is lost as heat and sound, so not all of the original kinetic energy is recovered. This is why the rebound is not perfectly as high as the drop.
