Stopwatch timing is a method used to measure the duration of an event or activity. A stopwatch is a handheld device that can start, stop, and reset to track time accurately. It is commonly used in sports, experiments, and various activities where precise timing is essential. To use a stopwatch, you press the start button when the event begins and the stop button when it ends. The display shows the elapsed time in hours, minutes, seconds, and fractions of a second. This information helps in analyzing performance, improving skills, and ensuring fair competition in events like races.
