Question

What does the slope of a Force of Friction vs Weight graph represent?

Answer 1

\[F=\mu \times N \]
\[W=m \times g.\]
\[\frac{ F }{ W }=\frac{ \mu N }{ mg}\]
let's assume that there is no additional forces just gravity and friction in equilibrium.
so N = mg cos theta
coefficient of friction = tan theta.
thus F/w=sin theta.

Answer 2

@Catch.me what does the sin theta represent?

Answer 3

coundnt you also say F/w = mu cos theta?

Answer 4

theta is the angle of inclination.
