  1. 3. Mechanical Energy/ energy stored in objects by the application of a force. Compressed springs and stretched rubber bands are examples of this type of energy.
  2. 4. Energy/ the type of energy produced when a force causes an object or substance to vibrate. The energy is transferred through the substance in a longitudinal wave.
  3. 5. a device that transforms kinetic energy (mechanical energy) into electrical energy.
  4. 8. Resources/ can’t be used up by humans. The sun is an example.
  5. 10. cell/ a device that transforms radiant energy directly into electrical energy. (Also known as a solar cell.)
  6. 11. the average kinetic energy of the individual particles of a substance.
  7. 12. Energy/ the energy of position or place. The higher up something is, the more of this type of energy there is.
  8. 13. of Conservation of Energy/ states that energy is never created or destroyed. Energy changes form, but the total amount of energy in the universe stays the same.

  1. 1. Resources/ resources that are renewable and cause less harm to the environment. Examples of these resources are solar energy, wind energy, and geothermal energy.
  2. 2. Plants convert radiant energy from the sun into chemical energy in the form of glucose (sugar).
  3. 6. a device with blades, which is turned by a force like wind, water, or steam. The mechanical energy of the spinning turbine is converted into electricity by a generator.
  4. 7. resources/ are used up much faster than they can be replaced. Fossil fuels and uranium are nonrenewable resources.
  5. 9. resources/ are energy sources that are replaced continually. These include hydropower, solar, wind, geothermal, and biomass.
