Presentation Transcript

  1. Energy Forms and Conversion

  2. ENERGYthe ability to do work

  3. WORKis done when you use a force to cause motion

  4. WORKa force is moved through a distance

  5. “CLUES” – Types of Energy • Kinetic Energy • Gravitational Potential Energy • Elastic Potential Energy • Chemical Energy • Thermal Energy • Electrical Energy • Nuclear Energy • Radiant Energy

  6. Kinetic Energy • Energy of motion • Examples: KE = ½*M*V2

  7. Gravitational Potential Energy • Stored energy that depends on an object’s height • Examples: GPE = M*g*H

  8. Thermal Energy • Energy of heat • Examples:

  9. Chemical Potential Energy • Stored energy in chemical bonds in compounds • When released, energy can do work • Examples:

  10. Elastic Potential Energy • Stored energy of a compressed or stretched object • Examples:

  11. Electrical Energy • Energy associated with electrical charges • Examples:

  12. Nuclear Energy • Energy stored within nucleus of an atom • Examples:

  13. Radiant Energy • Energy that travels through space in waves • Electromagnetic Spectrum • Examples:

  14. Sound • Form of kinetic energy • – movement of energy through substances in the form of waves

  15. Energy Conversion Cards • Front: • Form of Energy • Back: • 3 examples On either side include: • Picture of one of the examples

  16. Practice on Your Own • Energy Tracker: Jerome’s Story

  17. Conversion To change from one form to another

  18. Remember the 8 forms of energy…

  19. A squirrel is walking along a telephone wire and then he falls off.

  20. I stretch a rubber band, aim it at a student, and let it go.

  21. An electric toaster is used to make toast.

  22. A parked car begins to roll down the hill.

  23. You jump up on a trampoline.

  24. You plug in the microwave and turn it on.

  25. A cloud is full of water. • Eventually, raindrops fall from the sky.

  26. You flip on a light switch and the lights come on.

  27. Sunlight makes a flower grow.

  28. You eat a Power Bar before running the mile.

  29. A coal-burning power plant produces electricity.

  30. Person is standing on a diving board. • They jump off.

  31. A Roller Coaster goes up and down hills.

  32. Gasoline in a car is burned and the car moves.

  33. You light the coals in a grill, then cook a hotdog.

  34. A nuclear reactor is used to make electricity. • I plug in a fan and turn it on.

  35. I plug in an electric blender and turn it on. • Then I eat the delicious milkshake.

  36. The sun causes carrots to grow. • A bunny eats the carrots and hops around.
