• ### Kinematics i

1. 1. Kinematics IDistance and Displacement Topic 2
2. 2. Distance vs. Displacement
3. 3. Distance vs. Displacement• On your notebook, elaborate on a deﬁnition for both distance and displacement.
4. 4. Distance vs. Displacement• On your notebook, elaborate on a deﬁnition for both distance and displacement.• Share your deﬁnitions with the person siting next to you.
5. 5. Distance vs. Displacement• On your notebook, elaborate on a deﬁnition for both distance and displacement.• Share your deﬁnitions with the person siting next to you.• Create a distance vs. time graph for your morning commute from home to chapel. (neatness is not an option, it’s a requirement)
6. 6. Think!
7. 7. Think!• What would a distance vs. time graph for Michael Johnson would look like? Draw one. (this is the 400 m dash - one lap around the track)
8. 8. Think!• What would a distance vs. time graph for Michael Johnson would look like? Draw one. (this is the 400 m dash - one lap around the track)
9. 9. Think!
10. 10. Think!• What about a displacement vs. time graph for that race? Draw one.
11. 11. Think!• What about a displacement vs. time graph for that race? Draw one.• What are some of the challenges of drawing one?
12. 12. Kinematics IISpeed and Velocity Topic 2
13. 13. Speed vs. Velocity
14. 14. Speed vs. Velocity• On your notebook, elaborate on a deﬁnition for both speed and velocity.
15. 15. Speed vs. Velocity• On your notebook, elaborate on a deﬁnition for both speed and velocity.• Share your deﬁnitions with the person siting next to you.
16. 16. Speed vs. Velocity• On your notebook, elaborate on a deﬁnition for both speed and velocity.• Share your deﬁnitions with the person siting next to you.• Create a speed vs. time graph for your morning commute from home to chapel. (try to create the most appropriate graph)
17. 17. Think!
18. 18. Think!• What would a speed vs. time graph for Douglas da Lua (down hill speed skater) would look like? Draw one.
19. 19. Think!• What would a speed vs. time graph for Douglas da Lua (down hill speed skater) would look like? Draw one.
20. 20. Think!

22. 22. Think!• What would the speed vs. time graph for this ping pong rally would look like? Draw one.
23. 23. Think!
24. 24. Think!• What would the velocity vs. time graph for this ping pong rally would look like? Draw one.
25. 25. Think!• What would the velocity vs. time graph for this ping pong rally would look like? Draw one.• What are the challenges to describe its motion?
