Question

define vibratory motion with example

Answer 1

vibratory motion changes its size or shape while motion. example: musical instruments like drums, violin etc

Answer 2

A motion in which a part of a body moves to and fro in a definite style while the rest of the body always remains fixed is called vibratory motion.

It is also important to note the difference between an oscillation and a vibration

In oscillation , the whole body moves to and fro along a definite path.

In vibration, on the other hand, a certain part or parts of the body always remain fixed and do not move while the rest of the body moves to and fro in a definite style.

For example --

When we pluck the strings of a guitar, only the string moves whereas the guitar remains stationary. In fact, all musical instruments such as the sitar, violin, tabla, drum etc produce vibratory motion
