WebIntroduction. Friction is a force that opposes motion between any surfaces that are touching. Friction can work for or against us. For example, putting sand on an icy sidewalk increases friction so you are less likely to slip. On the other hand, too much friction between moving parts in a car engine can cause the parts to wear out. WebThe force of static friction F s F_s F s F, start subscript, s, end subscript is a force between two surfaces that prevents those surfaces from sliding or slipping across each other. This is the same force that allows you to … chain pulleys for lifting
