Question

what is angle of friction ?prove that the tangent of angle of friction is equal to the coefficient of friction​

Answer 1

Answer:

So, the coefficient of static friction is equal to the tangent of the angle at which the objects slide. A similar method can be used to measure μk. To do that you give the top object a push as you increase the angle. When the top object keeps sliding with constant velocity, the tangent of that angle is equal to μk.
