Question

vibration is a repeated ______ and ______ motion​

Answer 1

Explanation:

A vibrating object is wiggling about a fixed position. Like the mass on a spring in the animation at the right, a vibrating object is moving over the same path over the course of time. Its motion repeats itself over and over again.

Answer 2

Vibration is a repeated back and forth motion​.

Explanation:

• Vibration is a periodic motion in which the particles of a medium or elastic body move back and forth about their mean position.
• It happens when the particles are allowed to respond to all types of forces that tend to restore equilibrium position.
• Vibrations can be categorised into two types: forced and free vibrations.
• When the system is disturbed for a moment and then allowed to move without restraint, free vibrations are produced.
• When a system is continuously acted upon by an external force, forced vibrations are produced.
