Dividing both sides of the equation by W and cos(a), we get the equation for the static coefficient of friction fr. fr = tan(a) where tan(a) is the tangent of angle (a) and equals sin(a)/cos(a). The friction force is the force exerted by a surface when an object moves across it - or makes an effort to move across it. The frictional force can be expressed as. Ff = μ N (1) where. Ff = frictional force (N, lb) μ = static (μs) or kinetic (μk) frictional coefficient. N = normal force between the surfaces (N, lb) Also, the static friction would never be larger than the weight component - because then there would be a net force up along the incline, and the ball would start rolling upwards. This also doesn't actually happen, so that also can't be true. The true situation must be that the static friction is smaller than the weight component.
