  1. 1. North, South, East, West
  2. 4. A force of attraction between objects that is due to their masses.
  3. 5. an object's distance and direction from a reference point
  4. 7. The sum of all forces acting on an object
  5. 8. a region of space that has a physical quantity at every point.
  6. 9. colliding objects stick together
  7. 11. The distance an object travels per unit of time (distance/time)
  8. 12. force a push or pull on one object by another that is touching it
  9. 13. speed and direction of a moving object
  10. 14. Distance and direction of an object's change in position from the starting point.
  11. 16. For every action there is an equal and opposite reaction
  12. 19. A push or pull exerted on an object
  13. 20. the starting point you choose to describe the location, or position, of an object
  14. 22. A measure of the gravitational force exerted on an object.
  15. 24. change in position
  16. 25. A force that resists motion between two surfaces that are in contact
Down
  1. 2. an object in motion will remain in motion unless acted upon by another force
  2. 3. a diagram showing all the forces acting on an object
  3. 6. the acceleration of an object is equal to the net force acting on the object divided by the object's mass
  4. 10. a force that one object can apply to another object without touching it
  5. 15. the forces two objects apply to each other
  6. 17. a measure of the change in velocity during a period of time
  7. 18. A quantity that has magnitude and direction
