Potential energy
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. [1] [2] The term potential energy was introduced by the 19th-century Scottish engineer and physicist William Rankine, [3] [4] [5] although it has links to the ancient Greek philosopher Aristotle''s concept of potentiality.
