PHY 101 Friction Objective Question

Question

The coefficients of friction (μ_s and μ_k) depend primarily on which factor?
Options
A The area of the surfaces in contact
B The relative speed of the surfaces
C The nature of the surfaces in contact
Correct Answer
D The mass of the object
Correct Answer

Option C is the correct answer.

Detailed Explanation

The lecture specifies that the coefficients of friction are dependent on the nature of the surfaces in contact and are independent of the area of surfaces in contact.

Hint

Different materials, like rubber on concrete versus ice on steel, have different frictional properties.
