Vibrations

Vibrations are like very tiny movements that happen very fast. Imagine if your toy car is driving over a bumpy road, it will shake and jiggle. This shaking and jiggling is called vibration.

Everything around us, including us, is always vibrating. Even when we are standing still, our bodies are always shaking a little bit. The ground we stand on, the air around us and even the things we use like phones and computers vibrate too.

When vibrations happen fast enough, they can make a sound. Our voices, music, and even the sound of leaves rustling in the wind are all caused by vibrations.

Vibrations can also be helpful in many ways, for example, if your mom wants to bake a cake and needs to mix up the ingredients, the mixer she uses vibrates to mix them all together properly.

Vibrations can also be big, like when there is an earthquake. When the earth shakes, it is vibrating really fast, and sometimes it can be so big that it can move things like buildings and trees.

So, vibrations are when things move fast and make a tiny or big shaking or jiggling movement, and they can make sounds too. They can be helpful, but sometimes they can also be scary.
