Static friction is friction between two or more solid objects that are not moving relative to each other. For example, static friction can prevent an object from sliding down a sloped surface. The coefficient of static friction, typically denoted as μ s, is usually higher than the coefficient of kinetic friction.
Coefficient of friction is dimensionless. ASTM D-1894 – Standard Test Method for Static and Kinetic Coefficients of Friction of Plastic Film and Sheeting is commonly used for measuring COF of polyurethane. The test measures the force required to pull one material across another. The force required to initiate motion is used to calculate the static COF.
