About This Product
Physics students use the stopwatch to time pendulum swings, falling objects and trolleys on ramps, and chemistry classes use it for rate-of-reaction experiments. Split timing records several points in one run, so average and instantaneous speeds can be compared from a single trial. Educational Instrument can arrange export supply of the Digital Stop Watch to São Tomé and Príncipe, Papua New Guinea, Tunisia, Costa Rica and Iran.
