Traction by definition is the force that causes a moving thing to stick against the surface it is moving along. In the case of tractors, the ability to transmit the power of the tractor through the drive train and tires to the ground to do work such as pulling another piece of equipment. ... Traction can be affected by air pressure, flotation ...

Pressure relieving and redistributing devices are widely accepted methods of trying to prevent the development of pressure ulcers for people considered as being at risk. The devices used include different types of mattresses, overlays, cushions and seating. These devices work by reducing or redistributing pressure, friction or shearing forces.

Flotation is the ability of an object to float on the surface of a liquid, supported by the buoyant force exerted by the liquid. It is a fundamental principle in physics, closely related to Archimedes' Principle, which describes the upward force acting on an object immersed in a fluid.

Buoyancy results from differences in pressure at different depths within a fluid. The buoyant force is the upward force exerted by a fluid on a submerged object. It acts in opposition to gravity and is responsible for lifting objects when they are placed in water or another fluid.

Flotation tires are characterized by their high volume, i.e., wider footprint and higher sidewalls. The higher volume allows these tires to run at very low pressures while still having enough air inside to carry the weight of the vehicle. Moreover, the wider footprint reduces the pressure per unit area on the ground, unlike thinner off-road tires.

Flotation and centre of buoyancy relate to performance because the higher an object floats in the water, the less resistance the water will create to its movement. This applies to all water sports, including: surfing, kayaking, sailing, skiing, dragon boat racing, water polo, synchronised swimming, and swimming.
