height | time1 | time2 | time3 | time4 | avg time |
2 m | 0.45 s | 0.43 s | 0.35 s | 0.36 s | 0.39 s |
1.8 m | 0.4 s | 0.5 s | 0.48 s | 0.42 s | 0.38 s |
1.4 m | 0.41 s | 0.36 s | 0.37 s | 0.33 s | 0.37 s |
1.1 m | 0.37 s | 0.33 s | 0.33 s | 0.40 s | 0.36 s |
1) Using one of your heights and times from when theobject was released to when the object hits the floor, calculate g.(This is an experimental value of g)
2) Using all of you height data points, figure out howto make a linear graph of height and time. Determine the slope ofthe graph. This is related to your second experimental value of g.Determine your second experimental value of g.
3) compare both your experimental values of g to thetheoritcal value.
4) What is the percentage difference btween yourexperimetal values of g and the accepted value, 9.81m/s2?
5) How do you account fo this difference?
6) Does the theoritcal value for g fall within the finalerror range (the uncertainity) of your experimentalvalue?
7) Explain with the primary limitation on your data andhow it can be corrected. What factor in the experiment had thebiggest effect on collecting valid data and how would you make theexperiment more accurate?
