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):
7.5, 69, 18.75
15,47, 37.5
30, 3, 75
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 began my observation by taking measuring tape and found the aproximate length in inches for my hand. Once I did that I measured the pendulum and made it equal to the length of my wrist.
Once I had done that I began the count, which came out to 69 counts/min. Then I multiplied the length of the string by how many centimeters are in an inch and I got the amount of centimeters in the string.
For the next pendulum I repeated the process only this time I doubled the string length as instructed and repeated the process the third time with the string doubled agian.
I Do feel that there was a lot of uncertainty with the observations because the length of the pendulum may not be as precise as I would like it, plus while timing the counts the pendulum continuously slows down
and the count speed increases. Not to mention the possibility of me miscounting.
&#Good responses. Let me know if you have questions. &#
