Capacity for doing work
- energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature.

In physics, 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 a measurement of the ability of something to do work. It is not a material substance. Energy can be stored and measured in many forms. Although we often hear people talking about energy consumption, energy is never really destroyed. It is just transferred from one form to another, doing work in the process.

Energy is the ability to do work. There are several types of energy, including thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, sound energy, elastic energy and so on.
Nov 27, 2017 · Energy Definition. In science, energy is the ability to do work or heat objects. It is a scalar physical quantity, which means it has magnitude, but no direction. Energy is conserved, which means it can change from one form to another, but isn’t created or destroyed.
