Give six examples of vibratory motion.

Hint: The examples of the vibratory motion will be those motions that involve vibration, that is, the to and fro movement at a faster rate. As the to and fro movement at a slower rate represents the oscillatory motion.

Complete answer:
About a fixed point, a particle moves to and fro, and this type of motion is called vibratory motion.
The only difference between the vibratory motion and the oscillatory motion is that when the oscillations are of high frequency or the particle is moving at a faster rate about a fixed point, then, that motion is called the vibratory motion, inversely, when the oscillations are of low to medium frequency or the particle is moving at a slower rate about a fixed point, then, that motion is called the oscillatory motion.
The examples of vibratory motion are given as follows.
A tuning fork set to vibrate is a practical example.
The vibration of the phone when it rings.
The vibration of the batter head of the drum when hit with a stick.
The vibration of parts of a vehicle when the engine starts.
The vibration of our eardrum when sound enters the ear.
The generator starts to vibrate when switched on.
The grinder jar starts to vibrate when the mixer is switched on.
\[\therefore \]The to and fro motion of particles about a fixed point is called the vibratory motion.

Note:
A type of motion in which a particle vibrates about a fixed point is called vibratory motion. A type of motion in which a particle moves to and fro about a fixed point is called oscillatory motion.
