The general expression for gravitational potential energy arises from thelaw of gravityand is equal to the work done against gravity to bring a mass to a given point in space. Because of theinverse squarenature of the gravity force, the force approaches zero for large distances, and it makes sense to choose thezero of gravitational potential energyat an infinite distance away.As we all know gravitational force will exist till we survive, therefore this is an energy.
