  3. 7. to apply a force
  4. 9. the amount of matter that makes up an object
  5. 12. the force that opposes movement between touching surfaces and always acts against the direction of motion.
  6. 13. The process of moving or changing position.
  7. 14. the distance something travels in a certain amount of time
