WebStatic friction (or stiction) arises due to surface characteristics at the microscopic level (e.g., mechanical interference of surface imperfections, electrostatic, and/or Van der Waals forces). Two objects in static contact need to have a force fₚ applied parallel to the surface of contact sufficient to break stiction. WebDec 22, 2024 · Equation for Static Friction Where: Fs = force of static friction in newtons (N) μs = coefficient of static friction (no units) FN = normal force between the surfaces in newtons (N) Maximum static friction is achieved when the inequality becomes an equality, at which point a different force of friction takes over as the object begins to move.
