Across
  1. 3. the friction in-between sliding and rolling objects
  2. 4. object falling due to gravity
  3. 5. the constant speed that a freely falling object eventually reaches
  4. 9. How much force is needed to change the direction of a 1 kg object
  5. 11. created to provide controlled amounts of force
  6. 14. The amount of friction a surface has against an object
  7. 15. a force that opposes and reduces motion on a large and microscopic scale
  8. 17. happens when 2 surfaces could move relative to each other but are not yet moving
  9. 19. if you deform an ideal spring twice as far, it will produce twice the force
  10. 21. geometrical shape factor that describes the relative ease an
  11. 23. Geometric sketch of an object isolated from everything except the forces acted upon it
  12. 25. V=V(initial)+gt
  13. 28. ½ (Cd)PA(v)^2
  14. 29. every action has an equal and opposite reaction
  15. 30. Picture D
Down

  2. 2. Picture B
  3. 6. Picture C
  4. 7. happens when two surfaces are in rolling contact with each other
  5. 8. the resistance of a fluid to flow
  6. 10. materials that break before stretching
  7. 12. W=mg
  8. 13. the push or pull on an object that can lead to motion
  9. 16. object in motion or at rest remains that way until affected by an outside force
  10. 18. created the idea of inertia
  11. 20. A=(change in velocity)/t
  12. 22. F=ma

  14. 25. Picture A
  15. 26. when all the forces are equal to zero
  16. 27. object dropped in air that experiences no air resistance
