The coefficient of static friction is typically measured using a coefficient of friction tester, which applies a force to an object on a surface and measures the force required to initiate motion. This force is divided by the normal force acting on the object to calculate the coefficient of static friction. The formula is μs = F / N, where μs is the coefficient of static friction, F is the force required to initiate motion, and N is the normal force exerted by the surface on the object. This measurement helps determine the resistance of the object to sliding motion on the surface.
