Gravitational energy is the potential energy associated with gravitational force, as work is required to elevate objects against Earth''s gravity. The potential energy due to elevated positions is called gravitational potential energy, and is evidenced by water in an elevated reservoir or kept behind a dam. If an object falls from one point to another point inside a gravitational field, the force of gra

READ MOREGravitational Potential Energy. by Ron Kurtus (updated 30 May 2023) The gravitational potential energy between two objects of mass is the potential of motion caused by their gravitational attraction. The attraction of the objects turns the potential energy into the kinetic energy of motion, such that the objects will move toward each other.
