BANKING OF TRACKS

A Banked Racing Track

Racing tracks are constructed to slope inwards, this is called BANKING. The reason for this is to have a force component acting towards the center of the race track due to the weight of the car. This will prevent the car from skidding off the track when turning on high speed.
The concept about this related to the idea of centrifugal and Centripetal forces which are both opposite and equal for a body under rotary motion.
