Describe four basic forms of energy.

is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become. Thermal energy is also called heat energy. is stored in the bonds of atoms and molecules - it is the energy that holds these particles together. Stored chemical energy is found in food, biomass, petroleum, and natural gas. is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants split the nuclei of uranium atoms to produce electricity. is the movement of electrons (the tiny particles that make up atoms, along with protons and neutrons). Electrons that move through a wire are called electricity. Lightning is another example of electrical energy.

Kinetic is motion. Gravitational potential energy depends on height off the ground. Thermal temperature.
