There are two equations from which a change in the gravitational potential energy u of the system of a mass m and the earth can
Colt1911 [192]
The change in the gravitational potential energy is represented by the equation
u = ΔPE = Δmgh
since the mass of the system will remain constant and the acceleration due to gravity will also remain constant, the equation will become
u = mg Δh
