In physics, potential energy is the energy that an object has due to its position in a force field or that a system has due to the configuration of its parts.[1][2] Common types 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 spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is the joule, which has the symbol J.
