Stop Watch

Stopwatch is a precision timing device used to measure elapsed time with high accuracy.

Scientifically, mechanical stopwatches use gear and spring mechanisms to track time intervals, while digital stopwatches rely on electronic oscillators (like quartz crystals) to count time precisely.

In practice, stopwatches are used in scientific experiments, sports, and industrial processes where exact measurement of time intervals is critical for analyzing reaction rates, performance, or process efficiency.
