  1. 5. change in velocity over time
  2. 7. a force that works against an object in motion
  3. 8. a quantity that specifies magnitude and direction
  4. 11. the type of mechanical energy determined by the height/ position of an object
  5. 12. the amount of "stuff" something is made of
  6. 14. the property which states that an object in motion resists change in motion
  7. 16. when a roller coaster ride is about to end, it has the same amount of energy as when it started (if none is lost through heat or sound)-- because of what law?
  8. 17. the force on an object due to gravity
  9. 18. a type of friction due to air resistance
  10. 19. distance over time in a specific direction
Down
  1. 1. when a system is not traveling at a constant speed or at rest it's equation is?
  2. 2. when fnet=0 the forces are...
  3. 3. a quantity that only specifies magnitude
  4. 4. the sum of two or more vectors
  5. 6. the type of force created by a string or cable
  6. 7. when something falling is only under the influence of gravity (no drag)
  7. 9. the upward force which supports an object which is also always perpendicular to that object
  8. 10. the type of mechanical energy caused by an object being in motion
  9. 11. the rate at which you do work over time
  10. 13. (kg x m^2)/s^2
  11. 15. the amount of energy transferred to an object
