Name Date Energy in One Form or Another ENERGY CONVERSION We have discussed most of the following types of energy: Type of Energy A. B. C. D. E. F. G. H. Kinetic Energy Gravitational Potential Energy Chemical Potential Energy Elastic Potential Energy Potential Difference or Voltage Magnetic Related Energy Electromagnetic Radiation Heat or Thermal Energy Abbreviation KE GPE CPE ELPE V MRE (Light) ER H There are several energy conversion devices on the demonstration table. Your job is to analyze each, and write down all of the energy conversions involved in the operation of the device. Use the abbreviations from above and follow the example (1) below. 1. Mass oscillating on a spring ELPE --> KE --> GPE --> KE --> ELPE --> repeat until all the motion is turned into heat (H) and the oscillation stops. 2. Pendulum 3. Solar Cell 4. Steam Wheel 5. Radiometer 6. Magnet moving through a coil of wire 7. Human Being 8. Rub your hands together about 40 times). 9. Electric Clock Name Date 10. Wind-up toys 11. Rotating Flywheel 12. Incandescent Light Bulb 13. Toy Shuttle 14. Super ball : Throw the ball up and describe the conversions from after the ball is released. 15. Sterling Heat Engine on a coffee cup. (Ice Bucket) 16. Bounce No Bounce balls HOMEWORK: SOME MORE CHALLENGING ENERGY CONVERTERS: 1. Try to write down the overall energy conversion involved in the operation of the following devices which you come in contact with every day; i.e., what type(s) of energy is put in and what comes out? ENERGY IN ENERGY OUT A. Television B. Toilet C. Clothes Dryer D. Jet Taking off 2. List the energy conversions that take place in an automobile engine. 3. What happened to the kinetic energy of a moving automobile that was moving and stopped? What happens to the energy in sound waves from a radio when the sound is turned off? What happened to the kinetic energy of a pendulum bob as it slowed down and came to rest?
