The friction force between two surfaces is modeled using the following equation: $f = \mu N$
where
$\begin{array} { l }
f = \text { friction force in newton } \
\mu = \text { coefficient of friction } \
N = \text { normal force in newton }
\end{array}$
What is the appropriate unit for $\mu$ if the preceding equation is to be homogeneous in units?
