Define the term "Gravitational Potential" and write down a formula which defines it.
The Gravitational Potential is the work done in moving a unit mass (1kg) from an infinite distance to a point in a radial gravitational field. The Gravitational Potential is defined as being zero an infinite distance away from the gravitational field.
Gravitational Potential, V = -sqrt(GM/r)
