Static friction is a force that keeps an object at rest and resists the force applied to it. It is the friction experienced when individuals try to move a stationary object on a surface, without actually triggering any relative motion between the body and the surface on which it is on. Static friction is the friction that exists between a stationary object and the surface on which its resting. The maximum force of static friction is comparative to the normal force, which means that if the normal force increases, the maximum external force that the object can endure without moving also increases. The coefficient of static friction is denoted by μs and is the ratio of the maximum force of static friction to the normal force. The maximum force of static friction is given by (fs)max = μs N, where N is the normal force. Once the force applied to an object exceeds the maximum force of static friction, the object starts moving, and kinetic friction takes over.
