Analysis Part 1: Analyzing uniform acceleration of data. The average acceleration of the data as 8300 mm/s 2 . These values vary from uncertainties in each of the measurements taken. The standard deviation would be 326.06. This is the standard uncertainty of our data. Velocity y = 425.62x + 5.3957 R 2 = 0.9991 0 50 100 150 200 250 0 0.1 0.2 0.3 0.4 0.5 Time in seconds Change in distance in mm Series1 Linear (Series1) Two graphs were drawn, one by hand and one by a the computer. The slope of the hand drawn graph was 436mm/sec. The graph the computer gave had a slope of 425.62. The average percent difference is equal to 2.4%. This means that the graphs slopes were very similar. The R value for the computer graph was .9991. This value is very close to one, meaning that the data has a very strong positive linear relationship. The acceleration value we determined was 8300 +/- 326.06. The expected value would be 9800mm/s 2 . Although this outcome is not perfect, we must also remember that the setup was not perfect. The paper strip did experience some friction and there are other things that could
