Question

Maximum Uncertainty of a Measurement?

Answer 1

Best Estimate ± Uncertainty. Example: a measurement of 5.07 g ± 0.02 g means that the experimenter is confident that the actual value for the quantity being measured lies between 5.05 g and 5.09 g. The uncertainty is the experimenter's best estimate of how far an experimental quantity might be from the "true value."

Answer 2

The experiment consists of releasing a steel ball from various heights hi and measuring corresponding free fall times τi . We used a variant of the Atwood’s machine for the measurement The information about the release and about the impact is transferred to the timer via connectors

the resolution of the measurement is 0.01[s]

Air resistance is disregarded for calculation

then I have to calculate the magnitude of the acceleration due to gravity including its uncertainty

By comparing this relation
