The oldest wheel found in archeological excavations was discovered in what was Mesopotamia and is believed to be over 5, years old. It was not used for transportation, though, but rather as a potter's wheel.

The combination of the wheel and axle made possible early forms of transportation , which became more sophisticated over time with the development of other technologies. They were invented in Mesopotamia about 5, years ago.
Have You Ever Wondered...
Though often thought of as one of the earliest inventions, the wheel actually arrived after the invention of agriculture, boats, woven cloth, and pottery. It was invented sometime around 3, B. During the transition between the Neolithic and the Bronze Age , the very earliest wheels were made of wood, with a hole in the core for the axle. The wheel is unique because, unlike other early human inventions such as the pitchfork—which was inspired by forked sticks—it is not based on anything in nature.
The wheel is not like the telephone or the lightbulb, a breakthrough invention that can be credited to a single or even several inventors. There is archaeological evidence of wheels dating back to at least 5, years ago, but no one knows exactly who invented them. Wheeled vehicles appeared later in various areas across the Middle East and Eastern Europe. The invention of the wheelbarrow—a one-wheeled cart used to transport goods and raw materials—is usually credited to the ancient Greeks.
However, earlier evidence of wheeled carts has been found in Europe and China. The wheel alone, without any further innovation, would not have done much for mankind. Rather, it was the combination of the wheel and axle that made early forms of transportation possible, including carts and chariots. That latter group built small, four-wheeled toys in modern-day Ukraine, Moldova, and Romania.
Ancient Mesoamericans, for example, also produced little wheeled figurines despite having no known contact with their old world counterparts. However, the western hemisphere suffered from a near-total lack of domestication-ready animals capable of pulling carts. Who Actually Invented The Wheel?

When a wheel is rolling along the ground, a fraction of the surface touches the ground. Yet this surface doesn't have to slide on the ground.
Friction mainly occurs in the axle and are greatly reduced. Rolling friction is much weaker than sliding friction. By rolling, wheels make it easier to move things from place to place. There are many forms of wheels, for example water wheels.
Why It Took So Long to Invent the Wheel
All depend on the same basic principle of rotation around an axis to help produce usable work with a minimum of effort. The invention of the wheel was of great importance not only as a transportation device, but for the development of technology in general, important applications including the water wheel used in watermill , the gear , and the spinning wheel.
More modern descendants of the wheel include the propeller , the gyroscope and the turbine. The wheel has changed the world in incredible ways.
ustanovka-kondicionera-deshevo.ru/libraries/2020-07-30/2768.php The biggest thing that the wheel has done for us is given us much easier and faster transportation. It has brought us the train, the car, and many other transportation devices.
Aside from the above-mentioned advantages wheel brought, it may have helped in other discoveries such as the screw. Vikidia currently has 2, articles.
