Question
if kinetic friction is parallel to the surface, the coefficient of friction, as usual, is known as static friction. So what is the coefficient of static friction?
Solution
The coefficient of static friction is a dimensionless quantity denoted by the Greek letter μs. It represents the ratio of the force of static friction between two bodies to the normal force between them. It is a measure of the amount of force needed to start moving a stationary object along a surface, relative to the force pressing the two surfaces together. The value of the coefficient of static friction depends on the two surfaces that are in contact. It's not related to the kinetic friction or the direction of the force.
