Data Table 2.3 Free Fall Run Number Three At = mass = Interval Ad Av (cm) (cm/s) (cm/s) (cm/$2) 1 3 4 10 CO Results 1. Select the Data Table that seems to have the "best run" data. State which table was chosen and explain the basis for your choice. 2. Using your best run data, make a graph of average speed versus time. Select the first value of average speed to have a designated time of t = 0. Each successive time will then be larger by an amount At. The slope of your best-fit line will then give you an alternative calculation of the average acceleration for this run. Write that slope on your graph, and show the calculation for that slope in the space below. 3. Calculate the percentage error between your slope value and the accepted value of 980 cm/s2. Show that calculation in the space below. 4. Are you able to conclude that your falling object was falling with the acceleration due to gravity? Why or why not? What other force or forces might have been acting on your falling object other than the force of gravity? Are you able to make any conclusion about other possible forces on your falling object
