Define friction. Prove that tangent of angle of friction is equal to coefficient
of friction. ​

Sagot :

Answer:

Explained below

Explanation:

- Friction is the force that opposes the motion between two or more objects/surfaces in contact with each other.

- On an inclined plane, the coefficient of static friction is given by the relation;

μ = F_max/F_n

Where;

F_max is maximum frictional force before slip = mg sin θ

F_n is normal force = mg cos θ

Thus;

μ = mg sin θ/mg cos θ

μ = tan θ
