How does static friction oppose motion? On which factors does the value of the coefficient of friction depend?
(N/A) Static friction opposes motion by acting as a self-adjusting force that prevents the initiation of relative motion between two surfaces in contact. It acts in a direction opposite to the applied force that tends to cause motion.
The coefficient of friction $(\mu)$ depends on the following factors:
$1$. The nature of the materials of the two surfaces in contact (e.g.,wood on wood,rubber on concrete).
$2$. The condition of the surfaces,such as their roughness or smoothness (degree of polish).
$3$. The presence of lubricants or contaminants between the surfaces.
