Misconception EGM044:

Gravitational potential energy is the potential to fall; an object will lose all of its gravitational potential energy as soon as it starts to fall (Herrmann-Abell & DeBoer, 2010; Loverude, 2004).

RG179001

The gravitational potential energy of a falling rock at 50 meters is half of the gravitational potential energy at 100 meters because the amount of gravitational potential energy an object has is directly proportional to the height the object is above the ground.
