Unformatted text preview: Trial 1= 0.59s Trial 2= 0.46s Trial 2= 0.47s Trial 3= 0.44s Trial 3= 0.47s Ave. = 0.45s Ave. = 0.51s 1.0m= ½g(0.45s) 1.0m= ½g(0.51s) g= 9.88 m/s 2 g= 7.69 m/s 2 Although our group’s g values differed by over 2 meters/second, it is still fairly obvious that mass did not affect the acceleration when one looks at our trial times. I believe that if we would have run a few more trials to cancel out the abnormally high trial one of the wooden ball, the results would have been much closer. The main source of uncertainty for this lab was a human’s inability to stop the stopwatch at the proper time. When working at times well under 1 second, reaction time becomes a major uncertainty. To help counterbalance this, we took multiple trials and found the average....
