Formula for kinetic friction
WebMar 14, 2024 · The formula to calculate the coefficient of friction is μ = f÷N. The friction force, f, always acts in the opposite direction of the intended or actual motion, but only parallel to the surface. Solving for the … WebOnce an object is moving, the magnitude of kinetic friction fk is given by f k = μ k N. where μ k is the coefficient of kinetic friction. Friction varies from surface to surface because …
