What are gears?

Gears are wheels with teeth that help things move by connecting to other wheels.

Imagine you're playing with a toy car. When you turn the handle, the car moves forward. That’s like how gears work, they take one kind of motion and change it into another.

How Gears Work

Think about two gears next to each other. One is bigger, like your mom's plate, and the other is smaller, like a tiny cup. When you turn the big gear, its teeth push against the small gear’s teeth, making the little one spin faster! It's like when you push a bigger wheel on a playground merry-go-round; it makes the whole thing go around, but if you're on the smaller part, you feel like you’re flying!

Gears in Real Life

You might find gears inside your bike or even in your watch. When you pedal, the gears help you move more easily, just like how pushing a big wheel helps you go faster!
