Question

Explain cofficient of friction and angle of friction

Answer 1

Answer:

The coefficient of friction between any two surfaces in contact is defined as the ratio of the force of limiting friction and normal reaction between them.

u= F / R

Angle with the resultant of force of limiting friction F and normal reaction R makes with the direction of normal reaction R is angle of reaction.

Explanation:

Answer 2

$\huge \mathfrak{Answer:-}$

$\large\underline\mathrm\red{Friction}$

It is the force which always oppose to the relative motion between the two contact surface. It is denoted by f. It depends on the rough ness of the contact surface normal reaction etc.

It does not depend on the area of the contact.

$\large\underline\mathrm\red{Law's \: of \: fraction:-}$

1. It always oppose to the relative motion between the two contact surface.

2. The ratio of the limiting friction force to the normal reaction for a gain pair of surface is always contact.

$\implies$F/N = constant = m

$\implies$F = m.N

$\implies$F = m.mg

$\implies$F = limiting friction force

$\implies$F = maximum friction force

$\implies$M = cofficient of friction.
