Wheels may be employed for other purposes, including a ship's wheel, steering wheel, potter's wheel and flywheel.Common examples tend to be found in transport applications. One of the wheels greatly reduces friction by facilitating motion by rolling together using axles. To ensure wheels to rotate, a second really should apply to the wheel about its axis, either using gravity or by use of another external force or torque.The English word wheel originates from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, an expanded variety of the main *kwel- "to revolve, maneuver ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, the second both meaning "circle" or "wheel ".Precursors of wheels, called "tournettes" or "slow wheels", were known in the Middle East with the 5th millennium BCE (one of the initial examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE).

The original evidence of wheeled vehicles appears inside the wife or husband of this 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), so that the question which culture originally invented the wheeled vehicle will be unsolved.The initial well-dated depiction of any wheeled vehicle (here a wagon — four wheels, two axles) is to the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated inside 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) becomes 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, such as Ljubljana Marshes Wheel), and in the Baden culture in Hungary (axle won't rotate). They are dated to c. 3200–3000 BCE.In China, the wheel was certainly present using the adoption from the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
