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

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.

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.
