the gravitational potential energy of an object comes from gravitational field (site 1).
the gravitational potential energy of an object comes from gravitational field (site 1).
where does the gravitational potential energy of an object come from (site 1)?
gravitational field
the factors that affect an object's gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in. thus, a book lying on a table has less gravitational potential energy than the same book on top of a taller cupboard and less gravitational potential energy than a heavier book lying on the same table. an object at a certain height above the moon's surface has less gravitational potential energy than at the same height above the earth's surface because the moon's gravity is weaker. note that "height" in the common sense of the term cannot be used for gravitational potential energy calculations when gravity is not assumed to be a constant. the following sections provide more detail.
potential energy
elastic potential energy is the potential energy of an elastic object (for example a bow or a catapult) that is deformed under tension or compression (or stressed in formal terminology). it arises as a consequence of a force that tries to restore the object to its original shape, which is most often the electromagnetic force between the atoms and molecules that constitute the object. if the stretch is released, the energy is transformed into kinetic energy.
