Question 3

Which three factors affect the gravitational potential energy of an object?

A Weight, velocity and height B Mass, the acceleration due to gravity, and height C Mass, velocity and height D Mass, height and time

The right answer is the one marked above.

Mass, the acceleration due to gravity, and height. They are the m, the g and the h of E_p = m g h, and nothing else enters the formula.

Velocity does not appear at all. A raised object holds the same potential energy whether it is moving or perfectly still.
