Energy is the ability to cause change or do WORK. WORK is to make something MOVE by applying FORCE to it. There are 7 Types of Energy that can cause things to MOVE, or do WORK.
Energy cannot be created or destroyed, but it can change form. THE LAW OF CONSERVATION OF ENERGY
ACHELMS ATOMIC/NUCLEAR ENERGY the energy created when the NUCLEUS of ATOMS join together or split apart. It is also the energy used in nuclear bombs and nuclear power plants to produce electricity.
ACHELMS CHEMICAL ENERGY the energy stored in a substance that is released during a chemical reaction. • Burning chemicals in fuel to make heat • Using chemicals in batteries to operate a toy • Digestion of chemicals in food to give things energy
AC HELMS HEAT HEAT/THERMAL ENERGY is the energy of the particles (atoms) that make up an object. The faster the particles move the more heat/THERMAL energy that is created.
AC HELMS ELECTRICAL ENERGY: the energy of moving ELECTRONS. Electrons moving through the wires of radios, TVs, lights and all electrical appliances are examples of electrical energy.
AC HELMS LIGHT/RADIANT ENERGY: Energy that travels in waves and can move through empty space. Light/radiant energy is often visible like sunlight, starlight and electrical lights. STARS
AC HELMS MECHANICAL ENERGYthe energy of MOVING objects. Any MOTION or MOVING object has mechanical energy (potential & kinetic energy combined) • riding a bike • hitting a hammer • a spinning windmill
AC HELMS SOUND ENERGY the energy of vibrations that can move through solids, liquids or gases. Cannot move through empty space. A guitar string vibrates to make sound. Vocal chords vibrate make sound. These vibrations cause the air particles to vibrate.
ALL 7 Forms of Energy can be either POTENTIAL OR KINETIC A guitar string being pulled back is potential sound energy. When the guitar string is released, it is changed to kinetic sound energy.
A CHANGE in one type of energy to another is called an ENERGY TRANSFORMATION
Identify the Type of Energy • Get out a sheet of paper. Number your paper 1-10. • Identify each type of energy. You may use your notes!
