Question: Which of the following factors does NOT affect the coefficient of friction between two surfaces?

Options:

Correct Answer: Surface area

Solution:

The coefficient of friction is independent of the surface area in contact; it depends on the materials and their surface roughness.

Which of the following factors does NOT affect the coefficient of friction between two surfaces?

Which of the following factors does NOT affect the coefficient of friction between two surfaces?

Step 1: Understand what the coefficient of friction is. It measures how much two surfaces resist sliding against each other.
Step 2: Identify the factors that affect the coefficient of friction. These include the types of materials and how rough or smooth their surfaces are.
Step 3: Recognize that the surface area in contact does not affect the coefficient of friction. This means whether the surfaces are large or small, it doesn't change how much they stick to each other.
Step 4: Conclude that the factor that does NOT affect the coefficient of friction is the surface area.
