WebPotential energy (P.E) is that form of energy having the ability or potential to do work but at present time it cannot do work or apply force on anybody. Hence, we say it’s the energy objects possess in virtue of their position and not motion. P.E comes from a matter and is an inherent property of anything having mass. Webenergy (KE), and potential energy (PE). We’ll get to PE in the next Chapter. Let’s look at work and KE. Definition of work done by a force: consider an object moving while a constant force F is applied to the object. While the force is applied, the object moves along some axis (x-axis, say) through a displacement of magnitude x = d.
