I have been reading quite a lot about the Physics behind car dynamics and I have gotten to a point which keeps confusing me, namely - brake locking.
I understand brake locking as the situation when the wheels of the car do not rotate anymore but the car is still moving - this causes the tires to rub against the asphalt.
This implies that the force used to decelerate the car will be the force of kinetic friction exerted by asphalt on the tires (I am not taking air resistance into account)
If the wheels weren't locked, the stopping force would be the force of rolling resistance on the wheels plus the friction between the braking pads and the rotor. (Please, correct me if I'm wrong, as I am not entirely sure)
How can we prove that the stopping force is larger when the wheels are not locked?
Apart from that, I read that the wheel-locking appears when the braking force is larger than the asphalt can provide - I am not entirely sure how to interpret this.
