Fundamental Principle : As an object is taken away from the surface of earth, work has to be done to overcome the gravitational pull between the two. This work done is stored in the system as its potential energy. Thus, the difference in the gravitational potential energy at the given height and at the surface of earth is equal to the work done in taking the object to the given height.

a) Gravitational PE of an object of mass m at a distance r from the centre of earth (mass M) is given by : U = ...
