Answer:

The answer is: D. Gravitational potential energy and kinetic energy.

Step-by-step explanation:

The value of the gravitational potential energy would then be given by: where m is the mass of the body and g is the acceleration of gravity.

If the body is dropped, it acquires speed and, with it, kinetic energy, while losing height and its gravitational potential energy decreases.

The answer is: D. Gravitational potential energy and kinetic energy.
