Let me explain. Gravitational potential energy is actually defined in terms of the work done against gravity
• Gravitational Potential Energy Formula. The gravitational potential energy stored in an object can be calculated by the formula: Ug = m.g.h. Where m is the mass of the object, g is the acceleration due to gravity which the object is experiencing and h is the height to which it is raised. The height h depends on what our reference point is
• The gravitational potential (V) at a location is the gravitational potential energy (U) at that location per unit mass: where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity
• In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended.
• In the same way, the gravitational potential energy of a massive wrecking ball depends upon two variables the height at which the ball is raised and the mass of the ball. Moreover, the mass of the ball and the gravitational potential energy has a direct relation between them
