  3. 5. object(s) falling through air experience
  4. 6. Force that pulls objects towards each other
  5. 9. What causes an object to start moving, stop moving, or change directions?
  6. 11. the resistance to change in motion
  7. 14. It is a push or pull

Down
  1. 1. The greatest velocity a falling object reaches
  2. 4. What is the combination of all forces on an object?
  3. 7. When object rolls across a surface
  4. 8. Force that two surfaces exert on each other when rubbed against each other.
  5. 10. Equal forces acting on a single object
  6. 12. when only gravity acting on an object
  7. 13. What is the SI unit for strength of force?
  8. 15. measure of gravity exerted on an object
  9. 17. Every object moves in a straight line unless acted upon by a force.
  10. 20. The acceleration of an object depends directly upon the net force acting upon the object
