Q.7 Differentiate between Mechanical Stopwatch and Digital Stopwatch.

Ans: Differentiate between Mechanical Stopwatch and Digital Stopwatch.

Mechanical Stopwatch Digital Stopwatch
It has two circular dials. It has no dials but a screen.
It has one knob which is used for It has two buttons. Pressing the left starting and stopping the stopwatch. By button starts the timer and long pressing this knob will reset the stopwatch. It has two buttons. Pressing the left button starts the timer and by pressing it again the timer stops, thus the elapsed time is shown. The right button is used for reset.
Its accuracy is up to 1/100th of alts accuracy is up to 1/1000th of a second. Its accuracy is up to 1/1000th of a second.
Generally the least count of analogue Generally the least count of digital stop
stopwatch is 1 s or 0.1 s.		 Generally, the least count of digital stopwatches is 0.01 s.
