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.
27 lis 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.
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.
