2 WORK Energy Kinetic Potential Mechanical Chemical Sound Thermal
Gravitational Electrical Radiant -- Light Elastic Nuclear Cover of Booklet

3 Sources of Chemical Energy
Types of Potential Energy: Chemical Potential Energy is the energy stored in the chemical bonds of a substance. That energy is released by chemical reactions. Chemical Energy Definition (Copy these questions and answer them tonight.) How do I use chemical potential energy? (leave space for your answer) List three sources of Chemical energy found in your home. a. b. c. Sources of Chemical Energy

4 Gravitational Energy Types of Potential Energy:
Gravitational Potential Energy is the stored energy between an object or substance and Earth. The amount of Gravitational energy will depend on the mass of the object and the object’s height above the earth’s surface. Types of Potential Energy: Gravitational Energy Definition How is Gravitational Potential Energy used to make electricity? (Draw a picture.) How is Gravitational Energy used in elevators? (Draw a picture.)

5 Elastic or Mechanical Potential Energy
Types of Potential Energy: Elastic Potential Energy is the energy stored in substances or objects that are compressed or stretched. Springs and Rubber Bands are excellent examples of this. Elastic or Mechanical Potential Energy Definition Describe how Elastic Potential Energy is used on Aircraft Carriers. How can your legs demonstrate Elastic Potential Energy?

6 Kinetic Energy The energy of _______movement______________. What are the types of Kinetic Energy? a. Mechanical b. Sound c. Thermal d. Electrical e. Radiant--Light f. Nuclear How do kinetic energy and potential energy interact with each other? The more potenetial energy something has, the more kinetic energy will result. What is the purpose of Energy Energy is the ability to complete work or to cause change Page 4

7 Sound Energy Mechanical Energy Things to know about Sound:
Types of Kinetic Energy: Mechanical Energy This is the energy that something has due to its motion. This is the MOST common type of energy. Types of Kinetic Energy: Sound Energy Is the energy that sound carries. Vibrating objects emit sound energy. Sound energy can only travel through matter. Things to know about Sound: It must travel through matter. It travels in waves. We cannot see sound, but we can see Mechanical energy. Sound it emitted or given off. It is the result of vibrations. Examples of Mechanical Energy: 1.Writing 2. Walking 3. Clapping 4. Spinning How does Mechanical Energy help you? It helps us get from place to place. It helps us chew our food. (other answers along these lines). Draw how Sound Energy is emitted. Guitar Plucking the strings causes them to vibrate. These vibrations cause the wood to vibrate and sound is made. Page 5

8 Thermal Energy Types of Kinetic Energy:
This is what we call “Heat”. It is transferred (or shared) in three different ways. Energy Transfer: Page 6

9 Electric Energy Nuclear Energy Types of Kinetic Energy:
This is the energy of an electric current. Types of Kinetic Energy: Nuclear Energy This is the energy stored in the center (or nucleus) of every atom. Nuclear energy is released in two types of reactions: Nuclear Fusion is the fusing or joining of two atoms. This is the reaction that creates the energy of the Sun. Nuclear Fission is the splitting of the nucleus of an atom. In nuclear power plants, Uranium atoms are split apart releasing energy. List every object in the classroom that uses electricity: How is Electricity produced? Water and gravity= Hydroelectric Coal Burning Natural Gas burning Nuclear powerWhat are sources of the fuel needed? Page 7

10 Or Electromagnetic Radiation
Types of Kinetic Energy: Radiation…… Light, Or Electromagnetic Radiation This is the energy which an object or substance may emit or give off. The energy travels in waves throughout all matter (even you!). Best example of a source of radiation is the Sun. Electromagnetic energy includes: light, X rays, radio waves, and magnetism

11 The Law of Conservation of Energy
Energy can’t be created. Instead it is changed to another form of energy. Energy may also be shifted from one region to another. The Law of Conservation of Energy Page 8
