... B. The amount of work an object performs as it moves toward the earth under the influence of gravity is its gravitational potential energy: PE = mgh where m = mass, g = acceleration of gravity (9.8 m/s2), and h = height. C. The gravitational PE of an object is a relative quantity because it depends ...
