Let’s assume we have a front-wheel drive (FWD) car, and we apply a torque (Cf) to the front wheels. At this point, assuming no slip condition, a friction force (Tf) will occur due to friction between the rotating wheel and the road. This force will be from left to right (according to the picture). Now what’s about the rear wheels? They are pushed forward by the car that is now moving thanks to the Tf and they can only begin rolling if the force between them and the road is backward. Is it correct or am I missing something? What happens if I have no torque (when I release the throttle) and when I brake?
