| Jan 3, 2023 at 3:49 | comment | added | rob♦ | It’s not true that kinetic friction contributes no acceleration. It does contribute substantially less acceleration than static friction, and the skidding friction is independent of the wheel speed. To see, consider the case of hard braking, where the wheels lock to the car and skid on the ground. Locked wheels are less effective at stopping the car (thus anti-lock brake systems on modern cars), and the vehicle is effectively unsteerable if the front wheels get locked, but a car with locked brakes will still eventually stop. | |

Fixed a typo.
