But there are two key differences. First, we have a different coefficient, μk. This is always less than the coefficient of static friction, μs, so kinetic friction is lower. (This is why cars have antilock brakes: If you keep the wheels from locking up and skidding, you can stop in a shorter distance.) As an example, when two steel surfaces interact (like a train car wheel on a track), the coefficient of static friction would be 0.74, but the coefficient of kinetic friction would be 0.57.
