Question

What is a measure of static friction?

Answer 1

Explanation:

An easy way to measure the coefficient of static friction is to place two objects together and then tilt them until the top one slides. The angle at which one object starts to slip on the other is directly related to the coefficient. When the two objects are horizontal there is no frictional force.

Answer 2

Answer---»»➷

■»»— Static friction is equal to the tangent of the angle at which the objects slide. A similar method can be used to measure uk. And to do that you give the top object a push as you increase the angle.
