Across
  1. 1. amount of gravitational force acting on an object
  2. 3. the only force acting on an object is gravity
  3. 4. gravity,electromagnetic,strong nuclear force,weak nuclear force
  4. 6. a push or a pull
  5. 8. force=mass*acceleration
  6. 10. total momentum remains the same through the convertion of momentum
  7. 12. force opposing the rolling motion in an object
  8. 16. force opposing the sliding motion of an object
  9. 18. force opposing movement of objects that are moving
  10. 19. force that opposes the initiation of movement
Down
  1. 2. the tendency of an object the resist change in motion
  2. 3. force not touching
  3. 5. for every action, there is an opposite and equal reaction
  4. 7. all objects attract eash other through gravity
  5. 9. an object in motion will stay in motion and an object at rest will stay at rest unless acted on by an outside force
  6. 11. air resistance is equal to gravity so the highest falling speed is achieved
  7. 13. all forces acting on a body
  8. 14. mass*velocity
  9. 15. forces requiring the touching of two or more objects
  10. 17. force opposing the motion of objects in contact with each other
