Static friction
Definition
Static friction is the force that prevents an object from moving when a force is applied to it. It occurs when two surfaces are in contact and not sliding past each other.
Analogy
Imagine trying to push a heavy box on the floor. The static friction is like a strong invisible hand holding the box in place, making it difficult for you to start moving it.
Related terms
Kinetic friction: Kinetic friction is the force that opposes the motion of an object as it slides over a surface.
Contact area: Contact area refers to the portion of two surfaces that are in direct contact with each other. It affects the magnitude of both static and kinetic friction forces.
Coefficient of static friction: The coefficient of static friction is a value that represents how difficult it is to start an object's motion on a particular surface.
