The Gravitational Potential Energy of a body at a point in a gravitational field is defined as the amount of work done in bringing the body from infinity to that point without acceleration.The gravitational potential energy at a point is always negative.
Mathematically,
Gravitational Potential Energy = Gravitational Potential X mass of body (m).
Dimensional formula of Gravitational Potential = M0L2T-2
Dimensional formula of Mass = M1L0T0
Putting these values in above equation we get,
The Dimensional formula of Gravitational Potential Energy is M1L2T-2.
The SI unit of Gravitational Potential Energy is Joule (J).
