Gravitational Potential

The worrk done in bringing a unit mass from infinity to that point. The assumption being that the gravitational potential is zero at infinity.

Gravitational potential,

U = gravitational potential [Jkg-1]
G = universal gravitational constant = 6.67x10-11Nm2kg-2
m = mass of body [kg]
r = distance from body [m]
