Question
The motion which is not oscillatory is:
- Vertical oscillations of a spring
- Motion of a planet around the Sun
- Motion of the simple pendulum
- 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
