Question

2. a) Why a stopwatch is considered inaccurate for measuring speed of a body?

Answer 1

Explanation:

Resolution is related to the number of digits on the device's display for a digital stopwatch, or the smallest increment or graduation on the face of an analog stopwatch. For example, if a stopwatch display shows two digits to the right of the decimal point, it has a resolution of 0.01 s (10 ms, or 1/100 of a second).
