What is Dimensional Formula of Gravitational Potential?

The Gravitational Potential at a point in a gravitational field is defined as the amount of work done in bringing a body of unit mass from infinity to that point without acceleration.The gravitational potential at a point is always negative, it is maximum (= 0 ) at infinity.

Mathematically,

Gravitational Potential at a point (V) = Work done (W) / mass (M)

Dimensional Formula of Work= M¹L²T^-2
Dimensional formula of  Mass = M¹L⁰T⁰

Putting these values in above equation we get,
The Dimensional formula of Gravitational Potential is M⁰L²T^-2.
The SI unit of Gravitational Potential is J kg-1.
