Assuming a car is traveling on a road. At some point, the driver stops accelerating the car, so it travels some distance and then stops.
Since the car's wheels are round and are rotating without slipping, friction must not be the force that stops the car eventually. So which force is it?
In a practical scenario,
When a sphere rolls on a surface, the sphere deforms near contact surface. The contact is therefore not at a single point ,but over an extended area. when one segment of this "area of contact" 'pushes on' the table more strongly than the other,the normal force on the sphere shifts.It lno longer passes through the centre,it is shifted towards the former segment.
This force,then has a torque in the opposite sense that tneds to cause an angular deceleration.
