ANALYSIS: 1. Using the average velocities for each interval as the instantaneous velocity at the midpoint in time, plot v for each midpoint of time. (That is, plot the average velocities against t-/2 rather than against t.) (See Fig. 3) 2. Draw a straight line which best fits the points. (See Fig. 3) The slope of this line is g in cm/sec². Compare this value to the accepted value of 980cm/sec² and find the percentage error. 3. Extrapolate the graph to obtain the velocity of fall, V. at the first mark on the tape which you used. 4. Calculate from your data 10 values of g and record it in the TABLE. Obtain the average value of g and compare it to your value you obtained from the graph and to the accepted value of 980cm/s². 5. Make a graph of position relative to the s, mark versus the time relative to that point. Fit a smooth curve to the plotted points. Describe the shape of this curve (See Fig. 4)
