W=-GMm/r

This work done is stored under the object as its gravitational potential energy                 

            U = - GMm/r

(i) Potential power is a scalar quantity.

(ii) Unit: Joule

(iii) Dimension: [ML²T^-2]

(iv) Gravitational potential power is usually negative in the gravitational field because the force is always attractive in nature.

(v) As the distance r raise, the gravitational potential energy converts less value i.e., it increases.

(vi) If r =∞ then it becomes zero (maximum)

(vii) In case of discrete distribution of masses

            Gravitational potential energy  

(viii) If the body of mass m is rotate from a point at a distance r₁ to a point at distance r₂(r₁ > r₂) then change in potential energy

            As r₁ is greater then r₂, the change in potential energy of the body will be negative. It seems that if a body is brought closer to earth it's potential energy decreases.

(ix) Relation in between potential gravitational energy and potential 

         U = mV

(x) Gravitational potential power at the origin of earth relative to infinity.

(xi) Gravitational potential energy of an object at height h from the earth surface is given by
