Bradley is standing on the top of a mountain holding a soccer ball. Which of these best describes what happens when he throws the ball over the edge?

• Both the kinetic and potential energy change, but the total energy remains constant.

• The potential energy decreases and the total amount of energy also decreases.

• The kinetic energy decreases and the total amount of energy increases.

• The kinetic energy increases and so does the total amount of energy.
