    • ______
    • time
  4. avg speed
    • total distance
    • ___________
    • total time
  5. what is velocity and how do you find it?
    • the speed and direction of an object
    • final speed-initial speed
  6. what is the measure of inertia?
    the tendency an object has to resist change in its motion
  7. what does the law of conversation of momentum state
    the total momentum of objects that colide is the same before and after the collision
  8. if you 100m in 25s. later you run the same distance in less time what happened to your average speed ?
    you average speed is 4m/s
  9. the amount of matter in an object
    mass
  10. the speed of an object at one instant of time is
    instintanious speed
  11. the tendency of an object to resist change in its motion
    inertia
  12. a change in speed or direction of an object
    acceleration
  13. the measure of difficult to change the speed or direction of an object
    momentum
  14. the speed and direction of an object
    velocity
  15. the distance travled divided by the amount of time taken to travel the distance
    speed
  16. what is the momentum of a car with a mass of 500kg traveling north at 15m/3
    500*15=7500kg*m/s
