    Question

    The motion which is not oscillatory is:

    1. Vertical oscillations of a spring
    2. Motion of a planet around the Sun
    3. Motion of the simple pendulum
    4. oscillation of a ball in a hemisphere
       

    Hint:

    Oscillatory motion is defined as the to and fro motion of the body about its fixed position.

    The correct answer is: Motion of a planet around the Sun

      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.
       The motion of the earth around the sun is periodic but not oscillatory
