EVERYDAY SCIENCE

Detailed explanation-1: -The working of clocks is rather complex. But all of them make use of some periodic motion. One of the most well-known periodic motions is that of a simple pendulum.

Detailed explanation-2: -Nearly all the clocks make use of periodic motion.

Detailed explanation-3: -Answer: All the clocks around the world are manufactured to show some circular periodic motion so that the accurate type of time measurement can be featured in all the clocks.

Detailed explanation-4: -The hands of the clock move in a circle about a fixed point. Hence, they definitely perform the circulatory motion. Since the hands of the clock are covering an equal distance in equal interval of times, we can call it a periodic motion.

Detailed explanation-5: -The hands of the clock move in a circular direction, they are said to be in a circular motion. Each hand of the clock also repeats its motion after a fixed interval of time, thus it is also an example of periodic motion.
