GPE is a form of mechanical energy caused by the height of the object above the surface of the Earth (or indeed, any other source of a gravitational field). The magnitude of the falling body depends on the mass, gravitational constant and height from which it is falling. The lesson offered by Hooke to Newton here, although significant, was one of perspective and did not change the analysis. Gravitational potential is the potential energy per kilogram at a point in a field. Essentially, this law is an extension of Newton's Third Law in which every action has an equal and opposite reaction. Since, work W is obtained, i.e. Image credit: NASA.
