Wheels also are for other purposes, maybe a ship's wheel, steering wheel, potter's wheel and flywheel.Common examples are only in transport applications. One of the wheels greatly reduces friction by facilitating motion by rolling together through axles. So that wheels to rotate, a short while must apply to the wheel about its axis, either via gravity or by use of another external force or torque.The English word wheel hails from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, a protracted model of the basis *kwel- "to revolve, maneuver around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, aforementioned both meaning "circle" or "wheel ".Precursors of wheels, termed "tournettes" or "slow wheels", were known from the Middle East by its 5th millennium BCE (one of the first examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE).

True (freely-spinning) potter's wheels were apparently utilised in Mesopotamia by 3500 BCE and possibly as soon as 4000 BCE, along with the oldest surviving example, that was obtained in Ur (modern day Iraq), dates to approximately 3100 BCE.The initial proof wheeled vehicles appears on the lover for the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), and so the question which culture originally invented the wheeled vehicle remains to be unsolved.The initial well-dated depiction of any wheeled vehicle (here a wagon — four wheels, two axles) is within the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated in the 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) happens to be dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE.Two kinds of early Neolithic European wheel and axle are known; a circumalpine form of wagon construction (the wheel and axle rotate together, like in Ljubljana Marshes Wheel), knowning that with the Baden culture in Hungary (axle will not rotate). They both are dated to c. 3200–3000 BCE.In China, the wheel was certainly present considering the adoption with the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
