Question

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

Answer 1

@UnkleRhaukus

Answer 2

yes

Answer 3

Where
the weight is \(W =mg\),
the normal force is \(N = W\cos\theta=mg\cos\theta\),
the friction force is \(f = \mu N=\mu mg\cos\theta\),
and the net force is \(F= W\sin \theta = mg\sin\theta\)

Answer 4

The friction force, in-terms of weight will be
\[f=\mu W\cos\theta\]

Answer 5

so does the slope represent = mu cos theta?

Answer 6

yep

Answer 7

does mu cos theta mean anything in physics?

Answer 8

the coefficient of friction is also\[\mu =\tan\theta\]

Answer 9

how so?

Answer 10

so the slope \(\mu\cos\theta\) becomes
\[\tan\theta\cos\theta=\]

Answer 11

how is mu = tan theta?

Answer 12

i think it is just a definition

Answer 13

use tan = sin /cos
