What is gravitational potential energy? Gravitational potential energy: 1. Whenever two material bodies or two electrical charges are situated at a finite distance apart, the system possesses potential energy. The potential energy is positive if the bodies or charges are present against force of repulsion and negative if force between them is attractive. In case of two material bodies, the potential energy is as  gravitational potential energy , while in case of electrical charges, the potential energy is called as electrical potential energy. Hence we shall calculate the  gravitational potential energy  of a body of mass m situated at a distance r from earth. Gravitational potential energy 2. The  gravitational potential energy  of a body at a point is defined as the work done in bringing the body from infinity to that point. 3. When we bring a body from outside into a  gravitational field , the field will itself do work on...
