8.2: Potential Energy

Thus, the value of the potential energy function is meaningless, and only differences in potential energy are meaningful and related to the work done on an object. In other words, it does not matter where the potential energy is equal to zero, and by choosing (C), we can therefore choose a convenient location where the potential energy is zero.

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.
