How accurately do you think you can measure elapsed time using your stopwatch? Give a range with a +. For
example, when using a ruler with millimeter marks we would measure 1.30 ± 0.05 cm. Do some research on
human reaction time to help you come up with your value.
. Explain what your results mean and whether or not they agree with an accepted value. If they do not agree
within a reasonable discrepancy, explain where the error may have occurred (i.e. measurements, instruments,
resistance, friction, etc.). If you were to repeat the experiment, could you eliminate some portion of the error
changing the procedure?
