The change of one energy type into one or more other energy type(s) is energy transformation, also known as energy conversion. The law of conservation of energy asserts that energy cannot be destroyed, merely transformed from one type of energy to another.
Energy exists in a number of forms that science is still discovering; however, the main types are light energy, chemical energy, mechanical energy, nuclear energy, electric energy, heat energy and sound energy. Each of those types has many subtypes, and all of those subtypes have a kinetic and a potential version of energy. Kinetic energy is the energy of movement, while potential energy is stored energy.Learn More
Power is the rate at which energy is transferred. It is measured as the rate of energy per unit of time or joules per second.Full Answer >
Electric energy is the energy created by electrons moving through an electrical conductor. The world is made of matter. All matter contains atoms that contain electrons that are always moving. When electrons are forced down a conductive path, such as a wire, the movement produces electricity, or electric energy.Full Answer >
Electromagnetic energy is a form of energy that can be reflected or emitted from objects through electrical or magnetic waves traveling through space. Electromagnetic energy comes in many examples including gamma rays, X-rays, ultraviolet radiation, visible light, microwaves, radio waves and infrared radiation.Full Answer >
Wind energy is a form of renewable energy produced through machines that use wind as their power source. Wind energy is only possible because of the sun.Full Answer >
