1. Forms of Energy

2. Ability to do work or cause change Produces Warmth Produces Light Produces Sound Produces Movement Produces Growth Powers Technology What is energy?

3. POTENTIAL KINETIC Stored energy or energy of position Gravitational, Stored Mechanical, Nuclear, Chemical Energy of motion Motion, Electrical, Sound, Radiant, Thermal Types of Energy

4. Gravitational Energy – energy of an object or substance has because of its position/ when it is lifted up. Anything “up high” Potential Energy

5. Stored Mechanical Energy – stored in an object by its position or its motion.A spring is an example. Must push or pull on an object Potential Energy

6. Nuclear Energy – energy stored in the nucleus of an atom A nucleus is at the center of every atom Nuclear Energy – energy stored in the nucleus of an atom A nucleus is at the center of every atom Potential Energy

7. Chemical Energy – energy stored because of its chemical makeup. Released by chemical changes in matter. Potential Energy Gasoline wood foodbattery

8. Mechanical (Motion) Energy – movement/ interactions of objects or substances from one place to another Kinetic Energy Kicking a soccer ball Gears on a ship Water falling

9. Electrical Energy – movement of electrons Energy that is carried by an electric current Kinetic Energy

10. Sound Energy – movement of energy through substances in the form of vibrations. Kinetic Energy

11. Radiant/ Light Energy – electromagnetic energy that travels in transverse waves Kinetic Energy sunlight Radio waves microwave

12. Kinetic Energy Thermal (Heat) Energy – internal energy of a substance due to the motion of particles making up the substance.

13. 1 – Energy can not be created nor destroyed, only changed. Law of Conservation of Energy 2 – Energy will always transfer from high to low. 3 – No energy transfer is 100% efficient. Energy Transfers

14. Name the Transfer Chemical to Mechanical

15. Name the Transfer Radiant to Chemical

16. Name the Transfer Electrical to Thermal

17. Name the Transfer Chemical to Mechanical

18. 1.Energy does work or causes matter to change. 2.Energy can not be created nor destroyed, only changed. (law of Conservation) 3.Energy always transfers from high to low. 4.Energy transfers are never 100% efficient. In Review

19. Potential Energy stored energy or energy of position Forms of Energy Gravitational, Stored Mechanical, Nuclear, Chemical Kinetic Energy energy of motion Forms of Energy Motion/Mechanical, Electrical, Sound, Radiant, Thermal/Heat Two Types of Energy
