	Description:		Transcript: There are several broad types of energy. Energy is measured in units of calories in the English system or joules in the international system of metric units. One broad category of energy is kinetic energy, or the energy of motion. A second broad category of energy is electromagnetic energy, energy carried by waves of light and other forms of radiation. A third form of energy is heat energy which is the random microscopic motions of atoms and molecules. A final category of energy is potential energy. Energy stored in different forms could be within the chemical bonds that release fuel energy, could be energy stored in electromagnetic fields, could be nuclear energy stored within the nucleus of an atom. All of these different forms of energy can be quantified, and they can often be turned from one form into another.
