When a driving tire of a car spins it exerts a backward force against the surface (road) which at the same time pushes the tire (and the car) to run forward. What type of force does the road exert on the tire?

kinetic friction

rolling friction

Explanation:
Detailed explanation-1: -Friction is a force that arises when things rub together. The frictional force between the road and tire is what allows the tire to “push” off the road, thus moving the car forward (Newton’s third law-the action is the pushing frictional force, the reaction is the forward movement of the car).
Detailed explanation-2: -“traction is the friction between a drive wheel and the road surface. If you lose traction, you lose road grip.”
