1. Forms of Energy Chapter 5 Energy and Energy Resources Lesson 1 Mr. Nigh Science 7

2. Energy Energy is the ability to cause change All the activities taking place in this picture require energy EnergyHasManyForms

3. Kinetic Energy The energy due to motion Kinetic Energy increases as mass increases Kinetic Energy increases as speed increases

4. Potential Energy-Stored Energy Theenergy of ofPosition OrChemicalcomposition

5. Gravitational Potential Energy Gravitational Potential Energy increases when weights are held overhead

6. Elastic Potential Energy The rubber bands elastic potential energy increases when you stretch the rubber band. Or compress a spring

7. Chemical Potential Energy Chemical potential energy is energy stored in the chemical bonds between atoms. It is released when chemical reactions take place.

8. Work Work is the transfer of energy that occurs when force is applied over a distance. This Is Work Not Work

9. Forms of Energy

10. Mechanical Energy The energy that moves objects

11. Sound Energy Sound results from the vibration of particles in solids, liquids, and gasses ***Since sound needs to originate from particles in the air vibrating, it cannot travel through Empty Space

12. Thermal Energy Thermal Energy The total amount of energy from the movement of particles that make-up objects Always moves from warmer to colder objects

13. Electric Energy When you turn on a fan, electric current runs through the motor. Electric energy is the energy that an electrical current carries.

14. Radiant Energy Energy transmitted through space in the form of electromagnetic waves

16. Nuclear Energy The center of an atom-the nucleus is where nuclear energy is stored. When a heavy atom breaks apart (fission) or when two small atoms join together (fusion) energy is released released

17. The Sun a controlled Fusion reaction due to vast amounts of heavy elements

18. Chemical Energy Energy that is stored in the chemical composition of matter

19. Study Questions 1.Which type of energy increases when you compress a spring? 2.Which type of energy increases when you lift a large box? 3.What is the energy of motion? 4.What form of energy is due to the motion of particles? 5.What form of energy can travel through space? 6.What form of energy is stored in the nucleus of an atom?
