More or less just a general question. So if the normal force is pretty much the weight of the object (mass times acceleration of gravity) and then the friction is that times the coefficient? So basically weight is what causes MORE magnitude of friction? We take the force vector of gravity, turn it around and multiply it by the coefficient of the frictioning items to get..the static friction...right? I'm starting to think teaching this with vectors ruins the obviousness of this whole thing. Soemone correct me?
