  1. X (m) X (m) X (m) X (m) t (sec) t (sec) t (sec) t (sec) How Can You Create the Following Position Graphs? Graph 1. Graph 2. Graph 3. Graph 4. A. Speed Up B. Turn Around C. Slow Down D. Stand Still

  2. V (m/s) 0 t (sec) V (m/s) V (m/s) V (m/s) 0 0 0 t (sec) t (sec) t (sec) How Can You Create the Following Velocity Graphs? Graph 1. Graph 2. Graph 3. Graph 4. Speed Up, then Slow Down B. Turn Around C. Walk Away D. Stand Still E. Walk Toward

  3. X (m) X (m) X (m) X (m) t (sec) t (sec) t (sec) t (sec) Which Object is Moving Faster (Greatest Speed)? Graph 2. Graph 1. B A B A Graph 4. Graph 3. B A A B Line A B. Line B C. Tie D. Can’t Tell

  4. V (m/s) A B 0 t (sec) Which Object is Moving Faster (Greatest Speed)? Line A B. Line B C. Tie D. Can’t Tell Which Object is Ahead? Line A B. Line B C. Tie D. Can’t Tell

  5. V (m/s) B 0 A t (sec) Which Object is Moving Faster (Greatest Speed)? Line A B. Line B C. Tie D. First B, then A E. First A, then B Which Object is Ahead? Line A B. Line B C. Neither D. Can’t Tell What Does the Intersection Represent? Same Position B. Same Velocity C. They Crash Into Each Other D. They Turn Around

  6. Create a Velocity Graph from a Position Graph

  7. Create a Velocity Graph from a Position Graph Velocity is the Slope of the Position Graph

  8. Slope = ∆x = 3.5 - 1.0 = +1 m/s ∆t 3.0 - 0.5 Create a Velocity Graph from a Position Graph (3.0, 3.5) ∆x (0.5, 1.0) ∆t

  9. Create a Velocity Graph from a Position Graph Slope = 0 Velocity = 0

  10. Create Position Graph from a Velocity GraphDoes the Velocity Graph tell you Where to Start?

  11. Line Stays at 1 m while Velocity is ZeroHow Far Do You Go from 3 to 6 seconds?

  12. You end up at 2.5 meter Position at 6 secondsHow Far Do You Go from 6 to 9 seconds?

  13. You End Up Back Where You StartedWhat Does the Graph Do Next?

  14. What is Average Speed While Moving?What is the Average Velocity While Moving?

  15. What is Average Speed While Moving?What is the Average Velocity While Moving?

  16. What is Average Speed While Moving?What is the Average Velocity While Moving?

  17. Area “Under” a Velocity Graph is Displacement 0.5 m/s  3 s = 1.5 m -0.5 m/s  3 s = -1.5 m -1.5 m +1.5 m

  18. Area “Under” a Velocity Graph is Displacement,even when Velocity Line has a Slope

  19. Area “Under” a Velocity Graph is Displacement,even when Velocity Line has a Slope Area = 4s  .5 m/s = 2 m Area = 1/2  4s  .5 m/s = 1m Area = 1/2  2s  .5 m/s = 0.5 m

  20. Or, Displacement is the Average Velocity times the Time

  21. E&P #17 + 0 - 1. When, if ever, is the animal to the left of the origin on the axis? (A) never (B) between t = 0 and t = 2 (C) none of these (D) between t = 2 and t = 4 (E) between t = 4 and t = 7 2. When, if ever, is its velocity negative? (A) never (B) between t = 3 and t = 7 (C) none of these (D) between t = 0 and t = 3 (E) between t = 2 and t = 4 3. When, if ever, is its velocity positive? (A) always (B) between t = 3 and t = 7 (C) none of these (D) between t = 0 and t = 3 (E) never 4. When, if ever, is its velocity zero? (A) around t = 1 (B) at t = 3 (C) between t = 2.5 and t = 4.5 (D) never (E) at t = 0

  22. E&P #19 What is the total distance covered between 0 and 16 seconds by the runner whose velocity is shown above? (A) 128 m (B) 80 m (C) 100 m (D) Can’t tell (E) None of the above

  23. V (m/s) 0 t (sec) V (m/s) V (m/s) V (m/s) V (m/s) 0 0 0 0 t (sec) t (sec) t (sec) t (sec) Which Graph Shows the Velocity of a Ball Thrown Straight Up, After it Leaves Your Hand? A B C D E
