Answer:

Potential energy is the energy possessed by the body by virtue of its position or configuration.

Consider a body of mass m at a height 'h' from the ground.

The amount of work done to raise this body to this height h against the force of gravity:

W=F×h where F is the force of gravity .

W=mgh
