# 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,
- Where
= gravitational potential [Jkg*U*^{-1}]= universal gravitational constant = 6.67x10*G*^{-11}Nm^{2}kg^{-2}= mass of body [kg]*m*= distance from body [m]*r*
