Handheld, so one student can time while another runs the experiment
About This Product
For a pendulum, students time several oscillations and divide by the number counted, which reduces the effect of their own reaction delay; the same approach works for travel-time and acceleration runs in Applied Mechanics. The stopwatch is reset before each independent trial, and the battery should be removed for long storage.
Frequently Asked Questions
Q1. How can reaction-time errors be reduced with the Educational Stopwatch Timer? Time several cycles or repeat the measurement and average the results, so the operator's reaction delay forms a smaller share of the total.
Q2. Can it be used for pendulum experiments? Yes. Time a set number of oscillations and divide the total by that number to get the average period.
