Question

what is periodic motion and time period?​

Answer 1

Answer:

Periodic motion, in physics, motion repeated in equal intervals of time. In each case the interval of time for a repetition, or cycle, of the motion is called a period, while the number of periods per unit time is called the frequency.

Answer 2

$\huge\bold\green {HOLA!!}$

$\huge\mathfrak\red{periodic \; motion }$

This is a type of motion where the object repeats its motion after a fixed interval of time. Examples pendulum of a clock, motion of child on a swing etc.

$\huge\mathfrak\red{time \; period }$

The time taken by pendulum bob to complete one vibration or one oscillation is called the time period of pendulum. The time taken by a vibrating object to complete one vibration is called its time period.
