A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel.

The Halaf culture of 6500–5100BCE is sometimes credited with the earliest depiction of a wheeled vehicle, but this is doubtful as there is no evidence of Halafians using either wheeled vehicles or even pottery wheels. [12] Precursors of pottery wheels, known as "tournettes" or "slow wheels", were known in the Middle East by the 5th millenniumBCE. One of the earliest examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700BCE. These were made of stone or clay and secured to the ground with a peg in the center, but required significant effort to turn. True potter's wheels, which are freely-spinning and have a wheel and axle mechanism, were developed in Mesopotamia ( Iraq) by 4200–4000BCE. [13] The oldest surviving example, which was found in Ur (modern day Iraq), dates to approximately 3100BCE. [14] Wheels of uncertain dates have also been found in the Indus Valley civilization, a 4th millennium BCE civilization covering areas of present-day India and Pakistan.

An Orthopaedics Textbook presented by Duke University Medical Center’s Division of Orthopaedic Surgery, in conjunction with Data Trace Internet Publishing, LLC, is a true head-to-toe, comprehensive discussion of orthopaedic topics. Now give the object 4 wheels. The normal force between the 4 wheels and axles is the same (in total) 981 N. Assume, for wood, μ= 0.25, and say the wheel diameter is 1000mm and axle diameter is 50mm. So while the object still moves 10 m the sliding frictional surfaces only slide over each other a distance of 0.5 m. The work done is 981 × 0.25 × 0.5= 123 joules; the work done has reduced to 1/40 of that of dragging. Roller Bearings – A bearing collar containing needle roller bearings, often the most common and well used bearings. Most suitable for medium duty applications, making the wheel easier to move.
