The document discusses position vs time graphs and velocity vs time graphs. It explains that position is graphed on the y-axis and time on the x-axis for position graphs. Velocity can be determined from the slope of the position graph. Velocity graphs show velocity directly on the y-axis rather than as a slope. Both graph types can provide information about an object's speed and whether it is slowing down, speeding up or stopping.

3. Time will be on the horizontal axis.

7. If the slope is constant, the job is easy: calculate it!

11. We can also tell how the velocity is changing.

14. In a velocity time graph: farther from the axis = faster.

15. In a position time graph: crossing the t axis means object passes the origin

16. In a velocity time graph, crossing the t-axis means object stops on its way from positive to negative velocity. (or vice versa)
