Physics of racing cars Racing cars are high performance cars. In order for them to be fast the cars body (and interior must be very light). F = a m By re-arranging Newton's 2nd it can be seen that the larger the mass of the car the smaller the acceleration the car will have. For the car to accelerate (or decelerate) there must be some friction in between the cars tyres and the road surface. This traction helps the car to move at a very high speed and if the traction isn't there the car won't move even though the tires are rotating. This can be seen when the road surface is icy and the cars loose grip, the wheels are rotating but the car doesn't move very fast. The force required to slide a tyre is called the adhesive limit of the tyre, or sometimes the stiction. The formula F µN shows the relationship between the frictional...
