ENERGY Energy: Its Form and Transformation Major Kinds of Energy 1. Potential Energy 2. Kinetic Energy 1. Potential Energy • Potential Energy is an energy that is stored in a n object at rest. • Ex: Stretched rubber band 2. Kinetic Energy • Kinetic Energy is energy in motion. • Ex: A ball rolling on the ground Kinetic and Potential Energy Different Forms of Energy • • • • • • • 1. Mechanical Energy 2. Chemical Energy 3. Radiant or Light Energy 4. Electrical Energy 5. Sound Energy 6. Thermal or Heat Energy 7. Nuclear Energy 1. MECHANICAL ENERGY • Mechanical energy is a form of energy possessed by moving objects. • It can either be Kinetic or Potential Energy. MECHANICAL ENERGY 2. CHEMICAL ENERGY • Chemical Energy is a type of energy stored in molecules. • Food from plants and animals contain chemical energy. Chemical energy 3. RADIANT OR LIGHT ENERGY • Radiant or Light Energy is a form of energy that travels in an empty space. • It can be in form of Light, ultraviolet rays, x-rays and radiation. Radiant Energy 4. ELECTRICAL ENERGY • Electrical Energy is produced by moving Electrons. Electrical Energy • Static Electricity- is produced when two different materials are rubbed to each other. • Current Electricity- is flowing electricity 5. SOUND ENERGY • Sound Energy is the energy produced by vibrating objects. When objects vibrate, sound is produced. 6. THERMAL OR HEAT ENERGY • Thermal Energy is present in everybody because of the motion of molecules. 7. NUCLEAR ENERGY • Nuclear Energy is produced during Nuclear Fusion and Nuclear Fission.
