UNIT 4 ENERGY FORMS OF ENERGY




-Chemical energy is stored in some substances and can be stored in batteries.


-Thermal energy is related to the movement of atoms in an object or substance. Heat and temperature increase with an increase of these movements.


-Electrical energy is the movement of charged particles between two different places. Electricity travels to homes and factories through metal cables. 


-Nuclear energy is stored in the atomic structure of all matter. Scientists release this energy by breaking down radioactive materials, such as uranium.


-Sound energy: Sounds are made by vibrations travelling through the air, a liquid or a solid object.


-Radiant energy is energy in the form of electromagnetic waves. Light is an example of radiant energy.


-Mechanical energy produces movement. It’s the energy that enables people and things to move, go faster or change direction. There are two types of mechanical energy: kinetic energy and potential energy. Kinetic energy results from the motion of an object. Potential energy is the energy that results from the position of an object.
