WebIn static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object. For the case of a brick… comparison with kinetic friction In friction WebStatic friction is a responsive force that increases to be equal and opposite to whatever force is exerted, up to its maximum limit. Once the applied force exceeds size 12 {f rSub { size 8 {s \ ( "max" \) } } } {}, the object will move. Thus size 12 {f rSub { size 8 {s \ ( "max" \) } } =μ rSub { size 8 {s} } N} {} 5.3
