Data and Analysis:
1. For each trial, calculate the average speed, Vav, by dividing the total change in
position by the total time interval that elapsed, t.
2. Use the data for the first trial to plot a graph of position vs time.
3. On the same piece of graph paper, plot a graph of position vs time for each of the
other trials you ran. label each graph with the number of the associated trial.-
4. The shape of a position vs time graph for motion at constant speed is a straight line.
Do your graphs have this shape?
