Results: Here are my findings for the conversion between “mouse units” and meters 516 − 67mu = 449mu = 2meters 1mu = 2 449 = 0.0045meters With this conversion, I can now find the differences in position in “mouse units”: Time (s) "Mouse Units" Difference from 0.1 0.1 81 0 0.2 112 31 0.3 166 85 0.4 245 164 0.5 345 264 0.6 461 380 Let’s take the difference between t=0.1 s and t=0.6 s and use it to find the acceleration due to gravity: y = 380 mu = 1.71meters y = 1 2 gt 2 g = 2 y t 2 = 2 ( 1.71 ) 0.25 = 13.68 m s 2 The percent error is 39.6% according to: δ = | v A − v E v E | × 100 δ = | 13.68 − 9.8 9.8 | × 100 = 39.6% These findings, as well as the percent error, tell me that something went wrong in the calculations; these findings contradict free fall acceleration. Conclusion: In this lab I have shown that it is possible to calculate free fall acceleration with only knowing displacement and time. However, what I saw during my calculations is that there must have been some errors that I made, be it in measuring mouse units, converting them, or during the actual calculations. The error may have also come from my equipment not being set up correctly. Wherever the error may have come from, this lab shows that, while it is possible to
