rubber band calibration

Your work on rubber band calibration has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.

0,14.74 9.32 I used the single-reduced copy and it was 9.32 on this ruler I then compared it to a full ruler and matched the measuments. These measurements are in cm. This rubberband it 1. I think that the measurements could be off by a litte +/- 0.03.

I know that it not accurate because there is some human error in most measurments. I could have pulled on the rubber band making it slightly longer then it really was. Also, I could have held it up some as well. I would assume that it is off by 0.03 0,13.94 0,13.99 0,13.86 0,13.51 0,14.01 End 8.99,8.98,8.87,8.76,9.02 1,2,3,4,5 +/- 0.03 9.03,9.01,8.93,8.80,9.05 weight of two dominoes 9.40,9.39,9.32,9.22,9.45 4 9.80,9.81,9.71,9.63,9.89 6 9.93,9.94,9.83,9.72,9.99 8 10.22,10.25,10.19,10.07,10.32 10 End 8.99,8.98,8.87,8.76,9.02,0.19 9.03,9.01,8.93,8.80,9.05,0.38 9.40,9.39,9.32,9.22,9.45,0.76 9.80,9.81,9.71,9.63,9.89,1.14 9.93,9.94,9.83,9.72,9.99,1.52 10.22,10.25,10.19,10.07,10.32,1.90 End The first row has the 5 lengths of the rubber band and then last is the newtons exerted on one domino by gravity. Second row is 2 dominos third row 4 dominos fourth row 6 dominos fifth row 8 dominos and the sixth row is 10 dominos. The curve in the graph of the first is a increasing at an increasing rate throughout. 1.22 1.91 0.3,0.34,0.75,1.23,1.47,1.9 0.11,0.04,0.01,0.09,0.05,0 8.89,9.12,9.41,9.65,9.98,10.22 0.10,0.09,0.01,0.15,0.05,0

I have more faith in the curve numbers. I would choose the uncertainity of +/-0.15. This is the farthest that the above question was off. I would also choose +/-0.15. Because of the questions above this is the farthet off any of the numbers were.

Your work on this experiment will be compiled and you will receive a more extensive analysis and a reply after the due date. I see no obvious problem with the results you have submitted.
