When a ball is dropped it bounces until it eventually stops. Why does this happen?

• Some of the ball's energy is lost.

• Some of the ball's energy is converted to other forms, such as thermal and sound.

• All of the ball's energy is eventually converted to potential energy when the ball stops bouncing.

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