Question

Select the correct answer.

Which term is a function of two surfaces, and not of a single surface?
O A. displacement
O B. angular velocity
O C. coefficient of friction
O D. acceleration due to gravity

Answer 1

The correct answer is C. coefficient of friction.

The coefficient of friction is a function of the two surfaces in contact, and not just a single surface. Displacement, angular velocity, and acceleration due to gravity are all properties that can be attributed to a single surface or object.
