Vibration is a wiggling or shaking movement that you can feel or sometimes hear. Think of it like when you shake a toy or a rattle and it makes a noise and feels bumpy in your hand. That's vibration!
Everything around us vibrates, even the things that look still. When something vibrates, it moves back and forth really quickly. That movement creates energy that travels through the air or through other objects. For example, when you hit a drum or clap your hands, the vibration created from the impact moves through the air and reaches your ears, making a sound.
Vibration can also be helpful in some cases. For instance, when you turn on an electric toothbrush, the small head begins to vibrate gently back and forth. This vibration helps to remove food and plaque from your teeth!
However, vibration can also be harmful if it's too strong or persistent. Sometimes, machines or tools can vibrate a lot, which can make them dangerous to use. It's important to pay attention to how much something is vibrating and to stop using it if it's too much.
Overall, vibration is a natural phenomenon that we experience all around us every day!
