WebThe static friction model is the classic model of friction of Leonardo Da Vinci: friction force is proportional to normal load, opposes the direction of motion, and is independent of contact area. The break-away force necessary to initiate motion from rest in static friction is often greater than the kinetic/dynamic (or Coulomb’s) friction force. WebStatic friction prevents sliding. Static friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction that the object would slide without friction. Static friction keeps gravity from pulling the cheese down the incline.
