## Energy – Wikipedia

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.

The fundamental unit of energy is the Planck’s constant ‘h’ that maps one cycle of back and forth conversion of electric and magnetic fields. Work is performed with the organization of these cycles into desired configurations. It appears that the number of these cycles does not increase or decrease; but they organize themselves in different ways. (See “Energy is not the ability to do work”)

Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object’s position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object’s temperature.

A uniformly moving (non-accelerating) body has fictitious motion only, which depends on an external frame of reference. By choosing an appropriate frame of reference, that velocity can be shown as zero. Therefore the kinetic energy is not because of “uniform motion”. The “kinetic energy” appears only at the moment of impact due to change in velocity.

Potential energy does not exist when a body is under equilibrium of forces. The potential energy appears only when the equilibrium of forces is disturbed, and a background force comes into play. In all instances when energy appears, active forces are present.

Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy (in that frame of reference), and any additional energy (of any form) acquired by the object above that rest energy will increase the object’s total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale.

Both matter and field are physical substances. Matter has mass; similarly field has energy. Each cycle of field has energy equal to Planck’s constant ‘h’. Mass may be looked upon as resulting from a condensation of such cycles.

Living organisms require available energy to stay alive, such as the energy humans get from food. Human civilization requires energy to function, which it gets from energy resources such as fossil fuels, nuclear fuel, or renewable energy. The processes of Earth’s climate and ecosystem are driven by the radiant energy Earth receives from the sun and the geothermal energy contained within the earth.

All different forms of energies are configured from the basic cycle of the field of energy ‘h’.
