µs
Definition
The coefficient of static friction (µs) is a measure of the maximum amount of friction that can exist between two surfaces before one starts sliding relative to the other.
Analogy
Imagine trying to push a heavy box on a carpeted floor. The coefficient of static friction is like the stickiness or grip between the box and the carpet. If the value of µs is high, it means there's more grip, making it harder for the box to start moving.
Related terms
Coefficient of kinetic friction: The coefficient of kinetic friction (µk) represents how much resistance there is between two surfaces in motion relative to each other.
Normal force: The normal force is the perpendicular force exerted by a surface on an object resting on it.
Static equilibrium: A state where an object remains at rest due to balanced forces acting on it.
