Formula Gravitational Potential Energy = Mass (kg)x Gravitational Acceleration x Height(m) Where, Gravitational Acceleration = 98 m/s 21) Gravitational potential energy (J) = work done to move a mass from one place to another through a gravitational field (use mgΔh or GMm(1/R11/R2) 2) Gravitational potential (Jkg1) = work done per unit mass to move a small object from infinity to that point (V=W/m)To define quantitatively what we mean by the strength of a gravitational field, which is merely the force experienced by unit mass placed in the field I shall use the symbol g for the gravitational field, so that the force F on a mass m situated in a gravitational field g is F = mg 521 It can be expressed in newtons per kilogram, N kg1 Physicslab Gravitational Potential Energy How to gravitational potential energy
