What are wheels?

Wheels are round things that help make moving easier, just like when you roll a toy car across the floor.

Imagine you're pushing a heavy box across the room, it's hard work! But if you put wheels under the box, suddenly it's much easier to move. That’s because wheels roll, and rolling is smoother than sliding. It's like how your shoes feel when you walk on carpet versus when you slide on a smooth floor.

Wheels are usually attached to something that moves, like a bike or a car. When you push the bike forward, the wheels spin as they move along the ground. This spinning motion helps you go faster and use less effort.

Think of it like riding a scooter: your feet push the board, and the wheels help carry you along without you having to push all the time.

Wheels are used in many things, from toy cars to big trucks. They make moving easier, whether you're rolling across the floor or zooming down the street on a bike. And best of all, they’re everywhere! Next time you see something roll, remember: it’s probably using wheels to help it move.
