The gravitational potential of a gravitational field is, in Newtonian mechanics, a scalar magnitude measured in joules per kilogram (J/kg), which is defined as the amount of workper unit of mass required to transport a body at a constant velocity from infinity to a given point in the gravitational field in question. According to Newton scholar J. Bruce Brackenridge, although much has been made of the change in language and difference of point of view, as between centrifugal or centripetal forces, the actual computations and proofs remained the same either way. Work Done By Gravity. Gravitational Potential Dimensional Formula: Its dimensional formula is [L² T-2]. In Einstein's theory, energy and momentum distort spacetime in their vicinity, and other particles move in trajectories determined by the geometry of spacetime.
