All of the ball’s energy is eventually converted to kinetic energy when the ball stops bouncing.

Detailed explanation-1: -As the ball falls towards the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of the ball will continue increasing as the ball gains momentum, until it finally collides with a surface. When the ball collides, the kinetic energy is transformed into other forms of energy.
Detailed explanation-2: -Some of the kinetic energy the ball has when it strikes the floor is retained, but other is transformed, so each time the ball bounces it loses a bit of its kinetic energy, and after several bounces it has so little of it left that it ceases to bounce.
Detailed explanation-3: -When a ball is dropped gravity pulls the ball toward the ground, slowing the ball down so that each bounce is shorter and shorter, until eventually the ball stops bouncing. The force of the ball hitting the hard ground puts an equal force back onto the ball, meaning it bounces back up.
Detailed explanation-4: -2) The reason they stop bouncing is because they are loosing energy. When you lift them up, you are giving them potential energy. As they fall, the potential energy changes into kinetic energy. While the object falls and as it moves back up after a bounce, the air is trying to slow it down.
Detailed explanation-5: -Much of the energy of the ball’s downward motion becomes upward motion as the ball returns to its original shape and bounces into the air. The energy in the ball that isn’t converted into motion becomes warmth.
