Question

Prove that gravitational potential difference is the work done in carrying a unit mass from one point to another in gravitational field​

Answer 1

Answer:

The work done on the mass is then W = Fd = mgh. We define this to be the gravitational potential energy (PEg) put into (or gained by) the object-Earth system. This energy is associated with the state of separation between two objects that attract each other by the gravitational force.
