Energy
In physics,
energy is that the quantitative property that has got to be transferred to an object so as to perform work on, or to heat, the thing.
Energy may be a conserved quantity; the
law of conservation of
energy states that
energy are often converted in form, but not created or destroyed. The SI unit of
energy is that the joule, which is that the
energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common sorts of
energy include the K.E. of a moving object, the P.E. stored by an object's position during a field (gravitational, electric or magnetic), the elastic potential
energy stored by stretching solid objects, the
energy released when a
fuel burns, the
energy carried by light, and therefore the
thermal energy thanks to an object's temperature.
Mass and
energy are closely related. thanks to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has the same amount of
energy whose form is named
energy , and any additional
energy (of any form) acquired by the thing above that
energy will increase the object's total mass even as it increases its total energy. For instance, after heating an object, its increase in
energy might be measured as a little increase in mass, with a sensitive enough scale. Living organisms require
energy to remain alive, like the
energy humans get from food. Human civilization requires
energy to function, which it gets from
energy resources like fossil fuels, fuel, or renewable energy. The processes of Earth's
climate and
ecosystem are driven by the
energy Earth receives from the sun and therefore the heat contained within the world.
