Across
  1. 1. The force applied to an object
  2. 10. Force that opposes motion
  3. 12. No momentum is lost or gained in collisions
  4. 13. Force that acts across empty space
  5. 15. Objects collide and bounce apart completely
  6. 18. An object at rest stays at rest, and an object in motion stays in motion unless an outside force acts on the object.
  7. 20. Force between objects with electric charge
  8. 21. Acceleration is directly proportional to the net force acting on it
  9. 22. Representation of both the magnitude (strength) and direction of a force
  10. 24. The change in momentum of an object
  11. 25. An objects resistance to changing its motion
  12. 27. The equal and opposite force the object applies back
  13. 28. Objects collide and some kinetic energy is lost to heat, sound, or deformation
  14. 30. For every action, there is an equal and opposite reaction
Down
  1. 2. Objects collide and stick together after impact
  2. 3. Objects begin at rest or moving together, then separate
  3. 4. Sum of all forces acting on an object
  4. 5. Force that surfaces exert on objects resting on them
  5. 6. Force when two objects are physically touching
  6. 7. A force directly applied to an object
  7. 8. gravitational force acting on mass
  8. 9. The attractive force between any two objects with mass
  9. 11. The quantity of motion an object has
  10. 14. A force transmitted through strings, ropes, cables, or chains
  11. 16. Visual representation of all forces acting on an object
  12. 17. Force between magnetic materials
  13. 19. Cause of an object to start moving, stop moving, or change direction.
  14. 23. Discovered three laws about how things move
  15. 26. Force of objects moving through the air
  16. 29. Amount of matter in an object
