A stopwatch is a type of timer that is used to measure a specific amount of time. It is typically used in sports, scientific experiments, and other timing-related activities. It consists of a dial, two buttons, and a display which can be digital or analog. The start and stop buttons are used to start and stop the timer and the display shows the elapsed time since it was started. Stopwatches are often used to keep track of lap times, measure reaction times, and to time events.
