  • 1. By: Rebecca Stemkoski Energy & Work
  • 2. What is Energy?
    • Capacity for performing work.
  • 3. What is Work?
    • The transfer of energy from one physical system to another, especially the transfer of energy to a body by the application of a force that moves the body in the direction of the force.
  • 4. There are Two Forms of Energy:
    • Potential
    • Kinetic
  • 5. What is Potential Energy?
      • It is something waiting to be converted into power. A raised weight, coiled spring, or charged battery has potential energy.
  • 6. What is Kinetic Energy?
    • The energy possessed by a body because of its motion.
  • 7. Where can you find Energy?
  • 8. Some places you can find energy:
    • Any electronic device that contains a charged battery.
    • Riding your bike down the road.
    • Bottle Rockets.
    • Driving a car.
    • Eating and Digesting food.
  • 9. What kinds of Energy did you use today?
    • -- Electricity, if you used electric lights , or a radio , or TV.
    • -- Light --that was what the electricity in the lightbulb was converted to.
    • -- Sound --that was what the electricity in the radio was converted to.
    • -- Chemical energy- -when you ate breakfast , it gave you strength.
    • -- Heat --if you cooked your food, or heated the house .
    • -- Nuclear energy- -if you enjoyed sunlight , because the Sun gets its energy by combining atomic nuclei of hydrogen to helium, deep inside it.
  • 10. What kind of Energy is being transferred when using an electric fan?
  • 11. Electric to Kinetic
  • 12. In a car battery?
  • 13. Chemical to Electric.
  • 14. Can it be converted back to chemical energy?
  • 15. Yes, when the battery is charged.
  • 16. In a rocket nozzle?
  • 17. Heat to Kinetic.
  • 18. Are We Running out of Energy?
    • Hydrogen fuel cells generate electricity
    • Advanced natural gas turbines
    • coal combustion
    • Wind power
    • Biomass energy
    • Alternative transportation fuels
    • Geothermal energy
    • Hot hydrothermal resources
  • 19. Indiana Standards
    • 5.1.1 Recognize and describe that results of similar scientific investigations may turn out differently because of inconsistencies in methods, materials, and observations*.
    • 5.2.4 Keep a notebook to record observations and be able to distinguish inferences* from actual observations.
    • 5.2.8 Recognize when and describe that comparisons might not be accurate because some of the conditions are not kept the same.
    • 5.5.1 Make precise and varied measurements and specify the appropriate units.
  • 20. References
