Antilock Braking Systems

Antilock Braking Systems#

Antilock braking systems (ABS) automatically release brakes when wheels are locked. Once the wheels recommence rolling, the ABS reapplies the brakes.

Part 1#

These stop a vehicle under slippery conditions in a more rapid and controlled fashion because:

Answer Section#

  • The coefficient of rolling friction is larger than that of kinetic friction.

  • The coefficient of kinetic friction is larger than that of rolling friction.

  • In rolling motion, a car’s wheels remain at rest relative to the road, and the coefficient of static friction is larger than that of kinetic friction.

  • In sliding motion, a car’s wheels remain at rest relative to the road, and the coefficient of static friction is larger than that of kinetic friction.

  • In sliding motion, a car’s wheels remain at rest relative to the car, and the coefficient of kinetic friction is larger than that of static friction.
