  1. Distance & Position A B Can you state the distance between the two cars?

  2. Distance & Position A B 25 -10 -5 0 5 10 15 20 Can you state the distance between the two cars?

  3. Distance & Position A B 25 -10 -5 0 5 10 15 20 What is the position of car A?

  4. Distance & Position A B 25 -10 -5 0 5 10 15 20 What is the position of car A? car B?

  5. Distance & Position A B 25 -10 -5 0 5 10 15 20 Imagine the numbers shifted left by 10, is distance changed?

  6. Distance & Position A B 25 -10 -5 0 5 10 15 20 Imagine the numbers shifted left by 10, is position changed?

  7. Distance & Position • Define distance. • Define position. • What is needed to define position that is not needed to define distance? • Which of these two is a vector quantity?

  8. Speed 25 -10 -5 0 5 10 15 20 meters Time = 0 seconds

  9. Speed 25 -10 -5 0 5 10 15 20 meters Time = 5 seconds

  10. Speed 25 -10 -5 0 5 10 15 20 meters Time = 10 seconds

  11. Speed 25 -10 -5 0 5 10 15 20 meters Time = 15 seconds

  12. Speed time pi pf ∆d avg speed 0-5 25 15 10 ? 2 m/s 5-10 15 5 10 ? 2 m/s 10-15 5 -5 10 ? 2 m/s

  13. Speed What equation was used to determine the speed of the car?

  14. Speed What equation was used to determine the speed of the car? v = d / t

  15. Distance & Displacement Define Displacement.

  16. Distance & Displacement Define Displacement. Give the equation for displacement.

  17. Distance & Displacement Define Displacement. Give the equation for displacement. ∆d = df - di

  18. Velocity What equation was used to determine the velocity of the car?

  19. Velocity What equation was used to determine the velocity of the car? v = ∆d / ∆t

  20. Velocity & Speed How is speed different from velocity?

  21. Velocity & Speed How is speed different from velocity?
