Question

Define:
1. Vibration
2. Amplitude​

Answer 1

Answer:

Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. The word comes from Latin vibrationem The oscillations may be periodic, such as the motion of a pendulum—or random, such as the movement of a tire on a gravel road.

Explanation:

The amplitude of a periodic variable is a measure of its change in a single period. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values. In older texts, the phase of a period function is sometimes called the amplitude.

Answer 2

Answer:

VIBRATION : Periodic back and forth motion of the particals of elastic body or medium

AMPLITUDE : the maximum displacement or distance moved by a point on a vibrating body
