I have currently learned in physics that car doesn't skid while rotating in circular path because frictional force act towards centre to provide balance.If a velocity of car is increased such that frictional force is not sufficient to maintain balance,the car will skid radially outward.This radially outward force=centrifugal force.But, I have daught how can centrifugal force become greater than frictional force because fs=centripetal force=centrifugal force?
