Additional information

Energy is a fundamental concept in physics that refers to the ability or capacity of a system to do work or produce an effect. It exists in various forms, including kinetic energy (associated with motion), potential energy (stored energy), thermal energy (heat), chemical energy (stored in chemical bonds), electrical energy, and more.

The SI unit of energy is the joule (J), although other units like the calorie (cal) and kilowatt-hour (kW·h) are also commonly used in different contexts.
