Unformatted text preview: This exists when the object is completely at rest, or the object is moving at a constant velocity. Equilibrium can be show by the equations below. 3. What is the coefficient of friction ? What is its numerical range? Can it be greater than one? Can it be less than zero? Does it depend on surface area? The coefficient of friction force of two objects and the objects themselves. The numerical range is between 0 and 1 except in special cases. No the friction coefficient cant be less than zero. Surface area does not play a role in the coefficient of friction....
