Across
  1. 2. the force that opposes motion for two touching surfaces
  2. 3. a push or pull applied to an object
  3. 4. speed in a given direction (vector)
  4. 6. how hot or cold an object is
  5. 8. acceleration with only the force of gravity acting on an object
  6. 11. between +,- charges
  7. 14. something that binds, fastens, confines, or holds together something
  8. 17. gives direction + amount
  9. 19. the speed of a reaction
  10. 23. to render more reactive
  11. 24. uses units of length to describe location of an object
  12. 25. the rate at which velocity changes
Down
  1. 1. an object used to measure motion
  2. 5. causes some radioactivity
  3. 7. the distance an object travels per unit of time note of changed position(scalar)
  4. 9. physical contact force
  5. 10. holds the nucleus together
  6. 12. occurs when an object changes position relative to reference point
