Question

derive an expression for the potential energy of a body mass M at a height h above the surface of the earth​

Answer 1

Answer:

The work done W on the body in lifting it to a height h is

W = force of gravity (mg) × displacement (h) = mgh

This work is stored in the body with it is at a height h in the form of its gravitational potential energy.

Gravitational potential energy,

P.E.=mgh
