Unformatted text preview: the software will cease to collect data. Repeat the process a total of 5 times and enter the data in Graphic Analysis to determine the final value of g . Results: Part 1: t (s) t (s) y (m) y (m) g (m/sr) g (m/sr) 1.48 .03 9.5 0.02 7.57 .268 1.70 .02 9.5 0.02 5.87 .143 Part 2: g (m/sr) g (m/sr) 9.8 .04 Data Analysis: Conclusion: With no air resistance an object accelerates at 9.81 m/si . During the experiment, both objects, the solid ball and wiffle ball, had slower acceleration rates than anticipated. The reason for the wiffle ball to accelerate slower was due to the air traveling through the holes in the ball that created resistance. Though the solid object had no holes, it still accelerated slower than the rate of free fall. This was due in part to experimental error. Perhaps the stopwatch was not started at the precise moment the ball was dropped. If there was no air, both objects would have ideally gotten 9.81 m/si ....
