Is was reading an explanation of how friction makes a car move which stated that the static friction between the road and the car 'locks' one part of the tyre in place and that, because the wheel still rotates, this causes a forward motion.
Why then, is friction between the tyres and the road often giving as a force that slows the car down?
My hypothesis is that the 'slowing friction' is a different thing than the 'pushing friction', but the two confusingly share the same name. More specifically, I think the 'slowing friction' is the rolling resistance of the tyres, which (I think) is an effect of the material properties of the tyre. Is this correct? If not, than what is the difference?
