Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.
Energy is an abstract scalar quantity associated with motion (kinetic energy) or arrangement (potential energy). Energy is not measured, it is computed.

Physics. Work Energy Power. Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time. This article discusses work, energy and power in detail.
7 lis 2024 · The term energy has an important physical meaning in physics and is an extremely useful concept. There are several forms energy defined in mathematics. In measure theory, let Omega be a space with measure mu>=0 and let Phi (P,Q) be a real function on the product space Omega×Omega.
Electrical energy is a form of energy resulting from moving electric charges. Some objects carry electrical charges. These charged objects can exert forces on each other.
