F k = μ k F N This equation is of the same form as that for maximum static frictional force, and defines the coefficient of kinetic friction, μ k , which has the same properties as μ s , but a different value. μ k is a property of the interacting materials, and, like μ s , is independent of orientation of the objects. The only significant difference between the two friction equations is that the

Unformatted text preview: first measures the friction between two stationary objects and its value is dependent on the force applied to one, while second measures a frictional force that only exists when one of the objects is moving and which is not depend on the force applied to the block....
