Calculate (to the nearest whole CID/82) the acceleration due to gravity, g, of your object #1 for each of your seven falling time intervals using g = 2Ay/(At)2 where Ay is the displacement and At is the falling time interval 2. Find the average value of the acceleration due to gravity. We will call this your experimental value for the acceleration due to gravity. Compare your experimental value of g to the accepted value of 9.80 x 102 cm/s2 using a percent error calculation. Part Two 1. Let's call each of the positions of your object #2 as y1, y2, y3, and the corresponding times as t1, t2, t3, ...... 2. Calculate the average velocity between successive points (1 and 2, 2 and 3, 3 and 4, etc.) yz ' y1 y3 ' yz Average velocity 1 to 2 = ------------- ; Average velocity 2 to 3 = ------------ ; etc. t2 "t1 t3 "t2 3. When an object is moving with a constant acceleration, the average velocity between two points in time is equal to the instantaneous velocity at a point halrvay between these times. Thus you now have the instantaneous velocity at 0.020000 3, 0.060000 3, 0.10000 5, . . . . , up to 0.580000 s. 4. Download and save the Microsoft Excel le that goes along with this lab (this is posted on D2LB). In the spaces provided type the times & instantaneous velocities. The Excel le will plot a graph of instantaneous velocity versus time for you. Copy and paste this graph into the indicated space on the lab report form (at the end of the Results section of the report form). Resize the graph as needed to completely ll the space provided. 5. The slope of your instantaneous velocity vs. time graph is the experimental value for the acceleration due to gravity in Part Two (Look at the equation of the line that Excel has shown to give you the slope). Find the % error between this and the accepted value. Questions for Experiment #2: Acceleration Due to Gravity The questions to answer are on the lab report form associated with the experiment
