Wheels, in partnership with axles, allow heavy objects to always be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels can be useful for other purposes, such as a ship's wheel, steering wheel, potter's wheel and flywheel.Common examples are merely in transport applications. One of the wheels greatly reduces friction by facilitating motion by rolling together while using axles. For wheels to rotate, a short while has to be relevant to the wheel about its axis, either by gravity or by the use of another external force or torque.The English word wheel is produced by the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, an extended mode of the fundamental *kwel- "to revolve, navigate around ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, rogues both meaning "circle" or "wheel ".Precursors of wheels, often called "tournettes" or "slow wheels", were known with the Middle East through the 5th millennium BCE (one of the first examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE).

The best evidence of wheeled vehicles appears inside the last half with the 4th millennium BCE, near-simultaneously in Mesopotamia (Sumerian civilization), the Northern Caucasus (Maykop culture) and Central Europe (Cucuteni-Trypillian culture), therefore,the question of which culture originally invented the wheeled vehicle remains to be unsolved.The primary well-dated depiction of one's wheeled vehicle (here a wagon — four wheels, two axles) is at 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) happens to be dated in 2σ-limits to 3340–3030 BCE, the axle to 3360–3045 BCE.2 types of early Neolithic European wheel and axle are known; a circumalpine kind of wagon construction (the wheel and axle rotate together, as in Ljubljana Marshes Wheel), thinking that of the Baden culture in Hungary (axle will never rotate). They both of them are dated to c. 3200–3000 BCE.In China, the wheel was certainly present while using adoption of this chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
