Final answer:
Rolling traction is not demonstrated when the tires slide across the road.
Step-by-step explanation:
The statement that rolling traction is demonstrated when the tires slide across the road is False.
Rolling traction is observed when an object is in rolling motion without slipping. This occurs when the bottom of the wheel is at rest with respect to the ground for a measurable amount of time. In the case of a car's tires and the surface of the road, if the tires roll without slipping, there must be static friction between the tires and the road surface, not sliding.
For example, when a car's tires roll without slipping, they maintain contact with the road surface and do not slide. This allows the tires to exert the necessary traction to move the car forward without slipping.
