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.
27 lis 2017 · 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.
Mechanical energy is the sum of kinetic energy and potential energy. It is the result of the movement or location of an object. A good example of mechanical energy includes a flowing river, a person running, or a wind blow. The energy is stored in objects; that is, as the object moves faster, the more energy is stored.
