Question

What is the physical meaning of the slope for the relation between friction and normal force

Answer 1

Coefficient of static friction

Explanation:

We have that the force of friction is given by the coefficient of friction multiplied by the normal force, like this:

`F_F=\mu F_N`

We know that an equation of a straight line the slope is expressed as follows:

`\begin{gathered} y=mx \\ \text{ m is the slope } \end{gathered}`

Which means that the slope of the line between the relation of friction and normal force is the coefficient of static friction
