Gravitational Potential Energy

Gravitational Potential Energy is the energy possessed by an object due to gravity. The gravitational potential energy of an object at a certain point in space is equal to the work done by gravity when the object moves from that point to the reference point (i.e. a specific horizontal plane).
The gravity potential energy of an object is determined by the gravity of the earth on the object and the relative position of the earth and the object on the ground. The greater the mass, the higher the position, and the greater the work ability of an object, the more gravitational potential energy the object has.
