Wheels are useful for other purposes, for instance a ship's wheel, tyre, potter's wheel and flywheel.Common examples are simply in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together through axles. To enable wheels to rotate, a minute needs to apply to the wheel about its axis, either using gravity or by using another external force or torque.The English word wheel was produced from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, an extended method of the main *kwel- "to revolve, move about ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, warriors both meaning "circle" or "wheel ".Precursors of wheels, termed "tournettes" or "slow wheels", were known with the Middle East via the 5th millennium BCE (one of the initial examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE).

The best proof wheeled vehicles appears in your other half belonging to the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), therefore question which culture originally invented the wheeled vehicle remains unsolved.The earliest well-dated depiction from a wheeled vehicle (here a wagon — four wheels, two axles) is over the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated from a Funnelbeaker culture settlement in southern Poland.The oldest securely dated real wheel-axle combination, that from Stare Gmajne near Ljubljana in Slovenia (Ljubljana Marshes Wooden Wheel) is right now dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE.Two types of early Neolithic European wheel and axle are known; a circumalpine types of wagon construction (the wheel and axle rotate together, like in Ljubljana Marshes Wheel), and that also on the Baden culture in Hungary (axle won't rotate). They both of them are dated to c. 3200–3000 BCE.In China, the wheel was certainly present together with the adoption in the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
