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
