Find out how a racing car reduces friction when racing and increases friction
when it needs to stop.
Answers
Answer:
hey mate here's ur answer
Explanation:
There are several ways to reduce friction:
The use of bearing surfaces that are themselves sacrificial, such as low shear materials, of which lead/copper journal bearings are an example.
Replace sliding friction with rolling element friction, such as with the use of rolling element bearings.
Improve overall lubrication either by changing viscosity, using differing or improved additives or through the use of different lubricants themselves, i.e., synthetics, solids

Racing car and friction
a certain object is moving then there is a certain pressure exerted by the air in the opposite direction which tends to resist the movement of the body this resistance offered by air is the friction. when a body moves with a certain speed it experiences a certain friction from all the sides due to resistance offered by air and also by the surface on which the object is moving.
In case of racing cars, the cars are meant to operate at very high speed now to achieve this speed the car body has been designed in a streamlined structure so that it experiences minimum friction that the air has to offer in the body design can cut through the air. The car is designed such that it has a very minimum gap between the surface on which it is moving and the body; this also allows it to reduce friction due to air.
The tyres of the car uses friction on its advantage as the tyre moves at a very high speed so that the rubber on the tyre literally starts to melt due to friction and this allows the tire to remain stuck to the ground and thus allows free movement.
