Coefficients of Friction

Here are some examples of coefficients of static and kinetic friction. Generally speaking, the "slipperier" the surfaces are against each other, the smaller the coefficients. Notice also that $\mu_S$ is usually larger than $\mu_K$. Also, while these examples don't show it, there's no reason why you can't have a coefficient of friction be larger than 1.
