- 4. measures how fast an object is moving in a given amount of time.
- 8. a force that opposes (goes against) motion.
- 9. flow of thermal (heat) energy between things that are touching.
- 10. the tendency for an object to keep doing what it is doing.
- 13. remaining steady and unchanged (stays the same.
- 14. the transfer of thermal (heat) energy by the movement of liquids or gases.

- 7. the exact location of an object.
- 11. measures how fast an object is moving (speed) AND the direction in which it is moving.
- 12. the higher the velocity and mass, the more momentum an object has.
- 15. the action or influence of people, groups or things on one another.
