Across
- 4. a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is used to raise heavy weights.
- 10. Energy stored in atomic bonds (ex. food, fossil fuels)
- 11. Energy that is stored by an objects position
- 15. Energy from the transfer of electrons
- 16. the distance traveled in a certain amount of time. The formula for speed is Speed= Distance / Time
- 17. heat transfer from direct contact
- 18. Heat transfer from waves (no direct contact)
Down
- 1. A push or a pull
- 2. Energy that is moving (being used)
- 3. The force that governs movement in the universe
- 5. Force opposing forces that cause a change in motion
- 6. Energy that is stored (not being used)
- 7. Density changes in fluids (liquids and gases) resulting in heat transfer. Warm fluids rise, cool fluids sink.
- 8. The process plants use to convert radiant energy (sun light) to chemical energy (glucose)
- 9. Force opposing forces that DO NOT cause a change in motion
- 12. Energy from the movement of atoms
- 13. Energy from waves (ex. Light)
- 14. plane a sloping ramp up which heavy loads can be raised
