Across
- 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.
- 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.
- 5. a device that transforms kinetic energy (mechanical energy) into electrical energy.
- 8. Resources/ can’t be used up by humans. The sun is an example.
- 10. cell/ a device that transforms radiant energy directly into electrical energy. (Also known as a solar cell.)
- 11. the average kinetic energy of the individual particles of a substance.
- 12. Energy/ the energy of position or place. The higher up something is, the more of this type of energy there is.
- 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.
Down
- 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. Plants convert radiant energy from the sun into chemical energy in the form of glucose (sugar).
- 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.
- 7. resources/ are used up much faster than they can be replaced. Fossil fuels and uranium are nonrenewable resources.
- 9. resources/ are energy sources that are replaced continually. These include hydropower, solar, wind, geothermal, and biomass.
