Your 'pendulum counts in-class' report has been received. Scroll down through the document to see any comments I might have inserted, and my final comment at the end.
** **
** **
Report one line per observation. Each line should consist the length of the pendulum being observed, the 1-minute count and the scale factor by which your reported length should be multiplied to get the length of the pendulum in centimeters. The three requested quantities should be separated by commas. Each line should therefore consist of three numbers, separated by commas. Don't include any words, units, or other information in any of these lines.
You may report as many lines as possible. Use the space below.
Your data report (start on the next line):
8, 129, 2.54
16, 90, 2.54
32, 65, 2.54
Add your description of how you made your observations. Include an explanation of how much uncertainty there was in each observation, and explain how you arrived at your uncertainty estimate.
Your explanations (start on the next line):
I measured the pendulums in inches. I measure in ticks (half cycles). There are 2.54 centimeters in an inch that is how I got the 3rd number reported above. I am about 99% certain on the last two readings. The 1st one however I am only about 95% certain. It was moving a lot faster therefore it would be easier to have missed a half tick.
Excellent data. I think you had it right the first time; thanks for rebusmitting.
