A student conducts an experiment with a ball. The student releases the ball, and it drops to the floor and bounces. What energy transformations take place from when the ball is dropped to when it hits the floor?

• Potential energy is converted into kinetic energy when the ball is dropped, and then kinetic energy is converted into sound energy when the ball hits the floor.

• Kinetic energy is converted into sound energy when the ball is dropped, and then sound energy is converted into kinetic energy when the ball hits the floor.

• Sound energy is converted into kinetic energy when the ball is dropped, and then kinetic energy is converted into potential energy when the ball hits the floor.

• Kinetic energy is converted into potential energy when the ball is dropped, and then potential energy is converted into sound energy when the ball hits the floor.
