WebDec 22, 2024 · Where F k is the force of kinetic friction, μ k is the coefficient of sliding friction (or kinetic friction) and F n is the normal force, equal to the object’s weight if the problem involves a horizontal surface and no other vertical forces are acting (i.e., F n = mg , where m is the object’s mass and g is the acceleration due to gravity). WebStatic friction prevents sliding. Static friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction that the object would slide without friction. Static friction keeps gravity from pulling the cheese down the incline.
