1 Position-Time Graphs

2 POSITION (m) TIME (s) v = v = 2 m/s [E] v = Δd Δt v =

3 + 3.8 m/s v = m/s v = v = ∆d t POSITION (m) TIME (s) The steeper the line on a P-T graph, the greater the magnitude (size) of the velocity for that interval.

4 Relating P-T graphs to Velocity I don't like you. Good.

5 Origin - + P(m) T(s) P - T Graph + slope Straight line Moderate slope Positive slope Uniform velocity Slow velocity Moving away to the right d1d1 d2d2 10 0

6 Origin - + P(m) T(s) P - T Graph + slope Straight line Steep slope Positive slope Uniform velocity Fast velocity Moving away to the right d1d1 d2d2

7 Origin - + P(m) T(s) P - T Graph No change in position No velocity (Uniform) d1d1 NO slope

8 P - T Graph Origin - + P(m) T(s) - slope Straight line Moderate slope Negative slope Uniform velocity Slow velocity Moving towards the left d1d1 d2d2

9 Origin - + P - T Graph P(m) T(s) - slope Straight line Steep slope Negative slope Uniform velocity Fast velocity Moving towards the left d1d1 d2d2

10 P(m) T(s) P - T Graph - slope Origin - + Straight line Steep slope Negative slope Uniform velocity Fast velocity Moving left and passing d1d1 d2d

11 Position (m) Time (s) ∆d = = 25 m ∆d = d 2 – d 1 = (+15) – (0) = +15 m
