242 - How do gears work together?

Imagine you're riding a bike. Gears are like toothed wheels that work together to change how hard or easy it is to pedal.

Here's how it works:

1. Two gears are connected by teeth (small pointy parts).
2. When one gear turns, it turns the other gear because their teeth fit together.
3. If a small gear is connected to a big gear, it takes more turns of the small gear to make the big gear turn once. This makes the bike pedals harder but you go faster.
4. If a big gear is connected to a small gear, it takes fewer turns of the big gear to make the small gear turn once. This makes the bike pedals easier but you go slower.

So, gears work together by fitting their teeth together and making each other turn. They help change the speed and effort needed to move something, like a bike or a machine.
