In kinematics we often compare position/time graphs with velocity/time graphs.  The key feature to remember is that the velocity/time graph will always represent the SLOPE of the position/time graph over any interval.

To successfully convert these position/time graphs below into a velocity/time graph, your first step should be to calculate the slope (rise/over) in each interval.

Below you can find a video which works through a similar problem if you wanted to see an example before trying them on your own.

If you were able to successfully convert the graphs above, increase the difficulty by introducing quadratic position/time graphs.  Remember that IF the position/time graph is a quadratic, you know that the velocity/time graph will be linear!

You can also help yourself in drawing the velocity/time graph by remembering that the vertex of the parabola of the position/time graph is going to be the x-intercept of the velocity/time graph.

The final hint for solving these types of problems, is remembering that you can actually break a parabola up into a bunch of small straight lines and by using those estimates to draw your velocity/time graph, you will get a remarkably close answer.

 

Now it’s time to try starting with a velocity/time graph and then converting to a position/time graph.  Feel free to check out the example video below first before trying some on your own.  Remember that the velocity/time graph represents the slope of the position/time graph.

These final questions are the extra special challenge questions!  There is a video below that shows how to deal with a velocity/time graph once a slope is introduced.  Remember that the velocity/time graph represents the slope of the position/time graph.
