1. SOL 6.2 a & e

2. ENERGY is… the ability to do WORK or cause change WORK is… when a FORCE moves an object a FORCE is… a push or a pull

3. STATES OF ENERGY POTENTIAL ENERGY STORED energy that is NOT being used…YET KINETIC ENERGY Energy in MOTION-- Energy that IS being used Roller coaster (potential) Roller coaster (kinetic) Spring pressed down Spring released Water behind dam Water released & falling Rocket on launch pad Rocket blasting off

4. An object will have MORE POTENTIAL ENERGY IF…. ~ It is HIGHER UP off of the ground ~ It has MORE MASS (heavier) At which point on this track would a roller coaster have the MOST POTENTIAL ENERGY? __ Which ball has the MOST POTENTIAL ENERGY? A)The less heavy ball B)The very heavy ball

5. An object will have MORE KINETIC ENERGY IF…. ~ It is MOVING AT A FASTER SPEED. ~ It has MORE MASS (heavier) Which vehicle below has MORE KINETIC ENERGY? (A) 75 mph(B) 50 mph Which vehicle below has MORE KINETIC ENERGY? (B) 75 mph(A) 75 mph

6. DIFFERENT FORMS OF ENERGY Both potential & kinetic energy come in many forms. Use each of the next six slides to complete your notes. Write the COMPLETE DEFINITION & DRAW EACH OF THE ILLUSTRATIONS for each form of energy.

7. CHEMICAL ENERGY Energy in chemical bonds of food, fuel, coal, batteries, etc. battery gasoline/oil food 1. wood coal

8. ELECTRICAL ENERGY Moving electrical charges (electrons) Power lines Power outlet Lightning 2. Wires and plugs

9. ELECTROMAGNETIC ENERGY (also called radiant energy) Light energy that travels in WAVES sunlight Light from a flame 3. lightbulb light

10. MECHANICAL ENERGY Energy of moving parts Pencil sharpener Mouse trap Bicycle 4.

11. NUCLEAR ENERGY Stored in the nucleus of an atom & released when atoms are split or joined together Nuclear power plant Energy inside atoms 5.

12. THERMAL (HEAT) ENERGY Energy of the moving particles (atoms/molecules) IN an object battery Cold stuff too! Warm stuff 6.

13. ENERGY TRANSFORMATIONS **Also called Energy Conversions Definition: When energy CHANGES from one form to another DRAW & LABEL the ENERGY TRANSFORMATIONS on the next 4 slides

14. DRAW & LABEL the ENERGY CONVERSIONS taking place with a FLASHLIGHT. Batteries Light & Heat Wires CHEMICAL ENERGY ELECTROMAGNETIC & THERMAL ENERGY ELECTRICAL ENERGY Switch (button) MECHANICAL ENERGY

15. Heat & Light CHEMICAL ENERGY MECHANICAL ENERGY Outlet, plug, & cord DRAW & LABEL the ENERGY CONVERSIONS taking place with a TOASTER. Button/Lever ELECTRICAL ENERGY THERMAL & ELECTORMAGNETIC ENERGY Toasted Bread

16. DRAW & LABEL the ENERGY CONVERSIONS taking place in PHOTOSYNTHESIS Plant changes sunlight & water into sugar (food) for plant! CHEMICAL ENERGY LIGHT WAVES ELECTROMAGNETIC ENERGY

17. DRAW & LABEL the ENERGY CONVERSIONS taking place in A CAR MECHANICAL ENERGY GASOLINE CHEMICAL ENERGY CAR MOVES!
