What are vibrations?

Vibrations are when something moves back and forth really fast, just like a jump rope that’s being shaken.

Imagine you're holding a spring, like the kind you might find on a toy car. If you push it down and let go, it bounces up and down. That's a vibration! It's not moving in one direction, like when you walk, but it's going up and down, or side to side, over and over again.

Think of a ball that’s been dropped on the floor. When it hits the ground, it bounces back up, then down again, and again. That bouncing motion is like a vibration. The ball isn’t just moving once; it's moving in a pattern: up, down, up, down.

Vibrations are all around us! They’re what make your phone ring, or why you feel the music when you're dancing. Even when you're sitting still, things like chairs and floors can vibrate, you just might not notice it unless something is really moving!
