Unit 2 Review
Across
- 6. Heat transfer between objects or particles that have direct contact.
- 8. Heat transfer caused by the movement of liquid or gases. Cold air or liquid sinks and hot air or liquid rises.
- 10. The amount of force that comes out of a simple machine
- 11. How far a force is applied
- 12. block heat and very little can pass through
- 13. "A bar that rotates around a pivot point to lift objects"
- 14. used to measure force (N)
- 16. Heat transfer over a distance due to electromagnetic waves.
- 17. "A rope wrapped around a wheel to help lift heavy objects"
- 19. "Used to split objects apart, hold objects in place, or lift objects from the ground"
- 20. Uses very little force to roll along the ground
- 22. A force in a certain direction. Equal to energy
Down
- 1. "Simple devise WITHOUT moving parts that changes the magnitude or direction of a force"
- 2. A push or pull (N)
- 3. allow heat to pass through
- 4. The movement of heat particles from hot to cold. It stops moving once there is an equal temperature.
- 5. "A rod with grooves that wrap around it going from top to bottom"
- 7. A ramp
- 8. A machine that combines 2 or more simple machines
- 9. The amount of work required to move a simple machine
- 15. Getting the best end result with very little wasted effort or heat
- 18. heat bounces off, does not get trapped
- 21. trap heat
