    Question

    The period of a periodic motion is the ________ interval of time after which the motion is __________.

    1. Average, repeated
    2. Mean, not repeated
    3. Largest, repeated
    4. Smallest, repeated

    Hint:

    periodic motion, in physics, motion repeated in equal intervals of time. Periodic motion is performed, for example, by a rocking chair, a bouncing ball, a vibrating tuning fork, a swing in motion, the Earth in its orbit around the Sun, and a water wave

    The correct answer is: Smallest, repeated

      A motion that repeats itself after a fixed interval of time is called periodic motion and the fixed interval of time is called period.
      Average, repeated is correct option
