  2. P/T Graphs (Position/Time) • Position and displacement are the same thing • A position time graph shows your displacement over time. • If the line goes up you moved forward • and if it goes down you moved backwards. • If you get to a position less than 0m you are behind where you started. 15 10 P (m) 5 3 2 1 t (s)

  3. P/T Graphs (Position/Time) 15 Slope 10 P (m) 5 3 2 1 t (s)

  4. P/T Graphs (Position/Time) 15 Or Slope Slope 10 P (m) 5 3 2 1 t (s)

  5. P/T Graphs (Position/Time) 15 Slope 10 d P (m) 5 t 3 2 1 t (s)

  6. P/T Graphs (Position/Time) 15 Slope and 10 v P (m) 5 therefore 3 2 1 t (s)

  7. P/T Graphs (Position/Time) The slope of a P/t graph equals velocity 15 10 P (m) 5 SlopeP/t 3 2 1 t (s)

  8. P/T Graphs (Position/Time) • A position time graph shows displacement (or distance from an initial position) over time. • If the line goes up you moved forward and if it goes down you moved backwards. • If you get to a position less than 0 you are behind where you started

  9. P/T Graphs (Position/Time) • constant forward motion • constant backward motion • constant acceleration • constant deceleration • no motion

  10. P/T Graphs (Position/Time) 15 10 position P (m) 5 3 2 1 t (s) time

  11. P/T Graphs (Position/Time) • constant forward motion 15 10 position P (m) 5 3 2 1 t (s) time

  23. V/T Graphs (Velocity/Time) • Shows your change in velocity over time 10 5 velocity V (m/s) 0 -5 3 2 1 t (s) Yes, at a constant velocity of 5 m/s time

  24. V/T Graphs (Velocity/Time) Slope 10 and a 5 velocity therefore V (m/s) 0 -5 3 2 1 t (s) time

  25. V/T Graphs (Velocity/Time) Slope 10 and a 5 velocity therefore V (m/s) 0 -5 3 2 1 t (s) time
