Gravitational potential energy (GPE) is an important physical concept that describes the energy something possesses due to its position in a gravitational field. Mechanical energy is the energy due to the position of something or the movement of something. In simple terms, it can be said that gravitational potential energy is an energy which is related to gravitational force or to gravity. The object is lifted in vertical direction by an external force, so the force to lift the box and the force due to gravity, F g F_g F g are parallel.
