Question

define the term gravitational potential energy. derive equation of gravitational potential energy of an object of mass, m, it be raised through a height h from the ground

Answer 1

Energy possesed by a body by virtue of its position is called potential energy

Derivation:

Let us consider the body of mass m raised from ground to the height h, the amount of work done against gravity is

W = F × h

But, F = mg, the weight of body

So, W = mgh
