Wheels

Wheels are circular objects that rotate around an axle, allowing for easier movement of vehicles and other heavy items. They reduce friction between the surface and the object, making it easier to transport goods and people over various terrains. Historically, the invention of the wheel was a significant advancement in human civilization, facilitating trade, agriculture, and travel. Wheels are integral components in many forms of machinery, including cars, bicycles, and airplanes, contributing to efficiency and speed in transportation. Their design and materials have evolved, but their fundamental purpose remains the same: to enable smooth motion.
