All ENERGY FORMS CAN BE CLASSIFIED INTO TWO TYPES POTENTIAL ENERGY - Potential energy is stored energy and KINETIC ENERGY - Kinetic energy is motion — of waves, the energy of position or gravitational energy. There are electrons, atoms, molecules, substances, and objects. There several forms of potential energy: are several forms of Kinetic energy: Mechanical Potential Energy is energy stored in an object Mechanical Moving Energy is energy of objects in motion. due to its position or its shape. Gravitational Potential When you ride a bicycle down a hill and pick up speed, the Energy is energy stored in an object's because of its height. gravitational potential energy is changed to moving energy. The higher and heavier the object, the more gravitational Radiant Energy is electromagnetic energy that travels in energy. When you are at the top of a hill on your bike you transverse waves. Radiant energy includes visible light, x-rays, have a lot of potential to move due to gravity. A dam storing gamma rays and radio waves. Light is one type of radiant water is another example of gravitational potential energy. energy. Sunshine is radiant energy, which provides the fuel Elastic Potential Energy is energy stored due to a stretched and warmth that make life on Earth possible. spring or rubber band. A bow and arrow have elastic potential energy when you pull the bow back. Thermal Energy, or heat, is the vibration and movement of the atoms and molecules within substances. As an object is Chemical Energy is energy stored in the bonds of atoms heated up, its atoms move and collide faster. Geothermal and molecules. Batteries, biomass, petroleum, natural gas, energy is the thermal energy in the Earth. and coal are examples of stored chemical energy. Chemical energy is converted to thermal energy when we Sound is the movement of energy through substances in burn wood in a fireplace or gasoline in a car engine. longitudinal (compression/rarefaction) waves. Sound is produced when a force causes an object or substance to Nuclear Energy is stored in the nucleus of an atom — the vibrate — the energy is transferred through the substance in energy that holds the nucleus together. Very large amounts a wave. Sound energy is far less than other forms of energy. of energy can be released when the nuclei are combined or split apart. Nuclear power plants split the nuclei of uranium Electrical Energy is delivered by tiny charged particles called atoms in a process called fission. The sun combines the electrons, typically moving through a wire. Lightning is an nuclei of hydrogen atoms in a process called fusion. example of electrical energy in nature.
