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.
