I said stay the same, the definition of co efficient is here http://simple.wikipedia.org/wiki/Coefficient_of_friction but the main part i saw not only here was
"The coefficient of friction is dimensionless, meaning it does not have any units. It is a http://simple.wikipedia.org/w/index.php?title=Scalar_quantity&action=edit&redlink=1 , meaning the direction of the force does not change its magnitude."
My teacher says it does but how can angle cause molecular change in surfaces interacting? I just figured that angle only had something to do with forces not that co efficient value.
