    Question

    The _______ of a ________ motion is the small interval of time after which the motion is repeated.

    1. Time, oscillatory
    2. Periodic, periodic
    3. Time, rectilinear
    4. Period, rectilinear

    Hint:

    periodic motion, in physics, motion repeated in equal intervals of time.

    The correct answer is: Period, rectilinear

      • Oscillatory motion is defined as the to and fro motion of the body about its fixed position. Oscillatory motion is a type of periodic motion. Examples of oscillatory motion are vibrating strings, swinging of the swing etc.
      • 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 __Time,_____ of a ___oscillatory_____ motion is the small interval of time after which the motion is repeated.
