1. One Dimensional Motion AP Physics C

2. Terms Displacement vs. Distance Displacement: Change in position (vector) Distance: How far an object has travelled (scalar) Symbol: Δx or Δx SI Unit: meter, m

3. Position

4. Terms Velocity vs. Speed Velocity: Rate of the change in position (vector) Speed: Rate of distance covered (scalar) Symbol: v or v SI Unit: meter per second, m/s

5. Average Velocity

6. Instantaneous Velocity

7. Terms Acceleration vs. Acceleration Acceleration: The rate at which velocity changes (vector) Acceleration: The rate at which speed changes (scalar) Symbol: a or a SI Unit: meters per second per second or meters per second squared, m/s/s or m/s 2

8. Average Acceleration

9. Instantaneous Acceleration

10. Position vs. Time Graph

11. What are the velocities?

13. Average Velocity on an x-t graph

14. v av vs v inst on an x-t graph

15. x-t graph vs motion of a particle

16. Instantaneous Velocity on an x-t graph

17. Velocity vs. Time Graph The slope of a v vs. t graph is the acceleration The area between the curve and the horizontal axis of a v vs. t graph is the displacement

18. Comparison of v-t to a-t graphs

19. Instantaneous Acceleration vs Average Acceleration from a v-t graph

20. v-t graph vs motion of a particle

21. x-t graph vs motion of a particle with acceleration

22. What are the accelerations and displacements?

24. Acceleration vs. Time Graph The slope means NOTHING The area between the curve and the horizontal axis is the change in velocity a t -10 m/s/s 10 s

25. Important Acceleration tells us how fast velocity changes Velocity tells us how fast position changes

26. Kinematics Equations (accelerated motion)

27. Falling Bodies, thrown up objects, and the y-direction All things fall at the same rate (neglecting air resistance) On earth that rate is 9.80 m/s 2 That rate is an acceleration The name of that acceleration is Gravity

28. Object moving in y-dir

29. Changing Acceleration

30. Velocity by Integration

31. Position by Integration
