Gravitational Potential Energy:

The gravitational potential energy (U) of a mass m1 at a distance R from another mass m₂ is

For the earth-particle system the gravitational potential energy is given as:

This concept of gravitational potential energy can be extended to a multi-particle system. In the multi-particle system the total gravitational potential energy of the system is sum over all pairs of particles. Thus, the total gravitational potential energy is given by,
