428 - How do wheels and axles help in transportation?
Wheels and axles are a great invention that helps make transportation easier and faster. Here's how:
- Less friction: Wheels reduce friction when moving heavy objects, like cars or bicycles. This makes it easier to move things from one place to another.
- Easier to roll: Wheels are round, which means they can roll easily on the ground. This allows vehicles to move smoothly and quickly.
- Axles connect wheels: The axles (the bars or rods) connect the wheels together. This helps to distribute the weight evenly, making it easier to push or pull the vehicle.
- Increased speed: With wheels and axles, vehicles can move faster and more efficiently. This is because the wheels can rotate quickly, and the axles help to keep them stable.
In short, wheels and axles make it easier and faster to move things from one place to another, which is why we see them in cars, bicycles, and many other types of transportation.
