In physics, energy is that the quantitative property that has to be transferred to associate object so as to perform work on, or to heat, the object .[note 1] Energy could be a preserved quantity; the law of conservation of energy states that energy are often reborn in type, however not created or destroyed. The SI unit of energy is that the joule, that is that the energy transferred to associate object by the work of moving it a distance of one metre against a force of one newton.The Sun is that the supply of energy for many of life on Earth. As a star, the Sun is heated to high temperatures by the conversion of nuclear separation energy because of the fusion of H in its core. This energy is ultimately transferred (released) into area chiefly within the type of beaming (light) energy.Common sorts of energy embody the mechanical energy of a moving object, the mechanical energy keep by associate object's position during a field of force (gravitational, electrical or magnetic), t...
