Wheels can be put to use for other purposes, perhaps ship's wheel, controls, potter's wheel and flywheel.Common examples are found in transport applications. One of the wheels greatly reduces friction by facilitating motion by rolling together with the aid of axles. So that wheels to rotate, some time is required to apply to the wheel about its axis, either in terms of gravity or by the application 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-, lengthy variety of the foundation of the *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, called "tournettes" or "slow wheels", were known in the Middle East by 5th millennium BCE (one of the primary examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE).

The very first evidence of wheeled vehicles appears on the lover within the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), so the question that culture originally invented the wheeled vehicle will be unsolved.The earliest well-dated depiction of any wheeled vehicle (here a wagon — four wheels, two axles) is for the Bronocice pot, a c. 3500 – 3350 BCE clay pot excavated in any 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.2 kinds of early Neolithic European wheel and axle are known; a circumalpine style of wagon construction (the wheel and axle rotate together, such as Ljubljana Marshes Wheel), and this of one's Baden culture in Hungary (axle will not rotate). They both of them are dated to c. 3200–3000 BCE.In China, the wheel was certainly present using the adoption of one's chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
