From Motion Maps to Position-Time Graphs

In this video, we're looking at how Motion Maps (essentially 1-dimensional diagrams) can be expanded into 2-dimensional diagrams (graphs) that arguably do a better job representing motion.

We can see that PT graphs can be effectively used to model Constant Motion (CM), Non-Constant Motion (NCM), and Uniformly Accelerated Motion (UAM).

Also, the slope of the line on a PT graph represents the velocity of the object. If the motion is Non-Constant or UAM, then finding the slope by using the entire displacement and the entire time interval will give you the average velocity for the entire motion.
