Static Friction: Factors & Magnitude Limits

AI Thread Summary
The limit of static friction between two objects primarily depends on the normal force and the coefficient of friction, which is influenced by the materials' properties and surface texture. The coefficient of static friction is generally larger than that of kinetic friction due to the greater interlocking of surface irregularities when at rest. Factors such as surface smoothness or roughness play a role, but the intrinsic properties of the materials are more critical. Cold welding can also affect friction in specific scenarios. Understanding these factors is essential for analyzing frictional forces, particularly in applications like blocks on inclined planes.

I'm curious as to what does the limit of the magnitude of static friction depends on between any two objects.
 
Physics news on Phys.org
what does the coefficient of friction depend on?
-how smooth or rough the surface of the objects are?
 
also, why is the coefficient of static friction larger than kinetic? Can someone explain this to me with reference to a block on an inclined plane. Thnx

The two material's properties.

No.

Caveat: Cold welds.
