The capacity of a system or a body to do work.
The capacity of a system or a body to do work. Energy exists in many forms – electrical, thermal, kinetic, potential – and while it can be converted from one form into another, it can never be created or destroyed. Energy is always conserved. The international standard unit of energy is the joule, defined as the work done by a force of 1 newton moving through 1 metre.
