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?

A)

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

B)

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

C)

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

D)

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

D) Both the kinetic and potential energy change, but the total energy remains constant. i just took this test

Kason · Answer 2

The correct answer is D), because, as he is throwing the ball, the potential energy, that was stored in the ball, changes into kinetic energy, but there is no energy increase or decrease.
