Answer 2

Vibration means move back and forth quickly.

• Vibration is a mechanical phenomena that causes oscillations around a fixed point.
• The oscillations can be periodic, like those of a pendulum, or random, like those of a tyre on a gravel road.
• Vibration is defined as a rapid back and forth or up and down movement around a point of equilibrium.
• The vibrations might be either periodic or random. It's possible that something vibrating will shake at the same time.
