vibration

A vibration is a feeling or movement that's like a gentle humming or shaking. When something vibrates, it makes a soft noise and moves slightly back and forth.

When we talk about vibrations, we usually think of them as movements or feelings that come from music or touch. Imagine you're at a concert and the speakers are playing loud music - that creates vibrations in the air that make your body feel like it's shaking gently. Or maybe you've been to a spa and got a massage where they used special machines to vibrate your muscles, helping to ease any tension. In science class, we might talk about how some objects can vibrate when you apply force or pressure to them - like the strings on a guitar string that produces sound when plucked.
