Q: What is the proper way to calculate the uncertainty of elapsed time using a manual stopwatch?
Homework Answers
The proper way to calculate the uncertainty of elapsed time using a manual stopwatch is-
First find the range of the elapsed times then make it half.
For example
If shortest time is t1 and largest time is t2 then
Uncertainty in time = (t2 - t1) /2

2) Another student measured the period of a simple pendulum using a stopwatch. However, instead of measuring a single period, he waited for 10 periods to elapse before stopping the stopwatch. He obtained the time t = 19.40 s for ten oscillations. Report the period and its uncertainty in an appropriate format (assuming that the absolute uncertainty in the time measurement is still the same, i.e. 8t = 0.2 s). Calculate the fractional uncertainty in the period measurement.
