Question
many cars have ABS, or anti-lock braking systems, which prevent the tires from skidding during hard braking, and thus stop the car in a shorter distance. How is this possible?
There are five multiple choice options: a) it uses kinetic friction between the tires and road, which is greater than static friction. b) it uses kinetic friction between the tires and road, which is less than static friction. c) it uses both static and kinetic friction between the tires and road. d) it uses static friction between the tires and road, which is less than kinetic friction. e) it uses static friction between the tires and road, which is greater than kinetic friction.
Explanation / Answer
e) it uses static friction between the tires and road, which is greater than kinetic friction.
ABS brakes prevent skidding of tires which is kinetic friction and inturn use traction to brake.(Static friction)
