CONCEPT: Friction: The opposing force which opposes the relative motion between two surfaces is called friction. It is denoted by f and the SI unit of the frictional force is Newton (N). Friction (f) = μ N. Where μ is the coefficient of friction and N is the normal force between two surfaces.

Note: The above text is excerpted from the Wikipedia article "Friction", which has ... WebFriction opposes this motion, so it must point opposite to the way the car is going. Again, it must be static friction. Note that the static friction force acting on the front wheels is the force that accelerates the car forward. It is considerably larger than the friction force on the rear wheels - all that force has to do is to provide ...
