In this video, we will look at the difference between "plot" and "sketch" as well as what you MUST have on an AP Physics 1 position vs. time graph to earn all the points. We then will look at how to properly use the best-fit line (and not the data table) to find the slope and therefore the speed. We figure out how to invert an incorrectly plotted graph and then look at the different shapes of position vs. time graphs.
