What is axle?

An axle is like the invisible stick that helps wheels move when you ride a toy car or go for a bike ride.

Imagine you're playing with your favorite toy car. When it zooms across the floor, you don't see anything making it move, but there's something special inside. That’s the axle! It connects the wheels, so when one wheel turns, the other does too. It helps them spin smoothly and keeps everything moving together.

Think of your bike. When you pedal, the wheels go round and round, but they’re connected by a stick in the middle. That stick is the axle. Without it, the wheels would just wobble and not move properly. It’s like the backbone of the wheel, holding everything together so you can ride smoothly.

If your toy car or bike had no axle, the wheels might turn all over the place, kind of like when you try to balance on one foot without any help!
