Wow! And that is why a full lockup and wheelspin in motorsport offer less grip to the racing driver. And that is also why ABS is such an important safety feature
Since friction force is a self adjusting force, it should be equal to the force experienced by CM of the tyre (until it reaches static value) for pure rolling to occur. So in a way friction helps in pure rolling by making the contact point stationary. If the acceleration of bike keeps on increasing, friction keeps on increasing and after friction reaches static value, it will not be able to support further rolling. Then slipping should start and constant kinetic friction will take over (assuming flat surface). This is what happens on wet or icy roads, where friction becomes lower than usual and the tendency of vehicle to skid becomes high even at low accelerations because both static and kinetic frictions are lowered.
Sir in rolling motion in rotation chapter ,why we use kinetic friction .we should use rolling friction which has different formula as compared to kinetic friction
When a car is skidding, the friction is kinetic friction. Kinetic friction is less than maximum static friction, so the car takes longer to stop than if you brake hard without skidding.
