Mu ($\mu$) is the co-efficent of friction and is a constant for any two materials in contact.

#### Explanation:

$\mu = \left(\text{force of limiting friction")/("normal force}\right)$

where normal force = mg (mass x gravity) on a horizontal surface.*
The value for g is variously represented as $9.8 \frac{N}{k g} , 9.81 \frac{N}{k g}$ or $10 \frac{N}{k g}$, depending on the text and curriculum.

*On an inclined plane, normal force is calculated using:
${F}_{N} = m \cdot g \cdot \cos \left(\theta\right)$, where $\theta$ is the angle of the incline.
