Last week we learned about how to make a time verses postion graph and tested how to use it in class. We did this by taking cars timing them by seconds using the clock and marking where they are each second. Then you make a graph with time on the x axis and position on the y axis and then you simply copy the data that you recorded on your previous experement and plot it on the graph. Then we learned how to caompare the trend lines which are the lines you make on your graph by the steepness of the slope.
