Question

periodic motion do the hand of a clock perform jistify your answer with reason​

Answer 1

Since the hands of a clock move accordingly at regular time intervals, they are known to exhibit periodic motion. Since the clock hands move in a circular direction, they are said to be in circular or rotational motion. Therefore, the clock hands are said to be in a periodic motion and circular or rotational motion.

Answer 2

Answer :-

Let's first understand what is periodic motion :-

Periodic motion :- When a moving particle or body repeats its motion after regular interval of time along a definite path is called periodic motion. Interval of time is called time period.

The path of periodic motion may be linear, circular, circular or any curve.

Periodic motion of a hand of clock :-

Hands of clock performs periodic motion because second hand, minute hand and hour hand covers equal distance after every second, minute and hour respectively. So, it is repeating its motion. Also it moves along a definite path inside the clock i.e. it is perfoming circular motion and after regular interval of time. Hence, hands of clock performs periodic motion.
