I understand intuitively that an automobile is set in motion because the wheels apply a force on the road in a backwards direction. Using Newton's 3rd law, the car gets propelled because the road applies a reaction force in the opposite direction. Before starting to ask my full question, I want to ask this: Is this forward reaction force considered friction? It's in opposition to the motion of the wheels. Therefore, I want to say yes it is. Okay, now for the important part, I know that there is rolling resistance because rolling objects eventually come to a stop. When the brakes are applied, the kinetic energy is dissipated into heat and the kinetic energy is reduced. What I don't understand is the contact happening between the contact of the road and car. There must be a force acting against the forward velocity. Is this static friction and rolling resistance (the same possibly?)? The tires should be slowing down and the static friction which prevents slipping would possibly come stop the car from sliding across the road. It needs to act in the opposite direction of motion of the car. How is my reasoning? The wheels take time to slow down but does this change their relative motion on the road? Is it a matter of the forces acting in opposition of the car now "win out" causing it to slow down?
