Wheels will be intended for other purposes, say for example ship's wheel, tyre, 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 if you use axles. To ensure that wheels to rotate, a flash would need to apply to the wheel about its axis, either by means of gravity or by the employment of another external force or torque.The English word wheel proceeds from the Old English word hweol, hweogol, from Proto-Germanic *hwehwlan, *hwegwlan, from Proto-Indo-European *kwekwlo-, lengthy type of the foundation *kwel- "to revolve, move ".Cognates within Indo-European include Icelandic hjól "wheel, tyre", Greek κύκλος kúklos, and Sanskrit chakra, link units both meaning "circle" or "wheel ".Precursors of wheels, often called "tournettes" or "slow wheels", were known inside Middle East by your 5th millennium BCE (one of the primary examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE).

They both of them are dated to c. 3200–3000 BCE.In China, the wheel was certainly present when using the adoption with the chariot in c. 1200 BCE,although Barbieri-Low[9] argues for earlier Chinese wheeled vehicles, c. 2000 BC.
