Question
Which describes the coefficient of friction?A. The force applied to overcome the friction of a stationary objectB. The force between interfacing surfaces of two bodiesC. The ratio of opposing forces acting between two bodies in motionD. The ratio of the force of friction between two bodies and a normal reaction force
Solution
The coefficient of friction is described by D. The ratio of the force of friction between two bodies and a normal reaction force. This coefficient is a scalar value that represents the amount of frictional force between two bodies in contact. It is usually denoted by the Greek letter μ. The value of the coefficient of friction depends on the materials used for the two contact surfaces.
