Forms of Energy


What is Energy Physicists, who are scientists who study force, motion and energy, say that energy is the ability to do work, and work is moving something against a force, like gravity. In physics, energy is the ability to do work, or the ability to move or elicit change in matter. In effect, the amount of energy something has refers to its capacity to cause things to happen. Measure of the ability of a body or system to do work or produce a change, expressed usually in joules or kilowatt hours (kWh).


Forms of Energy


Mechanical Energy In the process of doing work, the object that is doing the work exchanges energy with the object upon which the work is done. When the work is done upon the object, that object gains energy. The energy acquired by the objects upon which work is done is known as mechanical energy.


Electrical Energy A form of energy that is produced when electrons move from one place to another place. Electrical energy is the energy newly derived from electric potential energy. When loosely used to describe energy absorbed or delivered by an electrical circuit (for example, one provided by an electric power utility) "electrical energy" talks about energy which has been converted from electrical potential energy.


Chemical Energy Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances.  Energy that is available for release from chemical reaction.


Electromagnetic Energy Light is a form of electromagnetic energy. Electromagnetic energy is also carried gamma rays, xrays, ultraviolet rays, visible light, infrared rays, micro Radio Waves. TV waves, etc.


Thermal Energy In thermodynamics, thermal energy refers to the internal energy present in a system by virtue of its temperature. Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated. Stoves and matches are examples of objects that conduct thermal energy.
