To find the gravitational potential, suppose we have a mass \(m\) creating a gravitational field in space. We put a small "test mass" \(m_{0}\) in space near mass \(m\), determine the gravitational potential energy on the test mass due to \(m\) 's mass, and divide the resulting potential energy by \(m_{0}\).
