Question

Identify the correct statement.

• A. Static friction depends on the area of contact
• B. Kinetic friction depends on the area of contact
• C. Coefficient of static friction is more than the coefficient of kinetic friction
• D. Coefficient of kinetic friction is less than the coefficient of static friction

Hint:

Static friction is always greater than kinetic friction for the same surfaces and materials.

Answer 1

The Correct Option is C

Step 1: Understanding friction types.
Static friction is the force that resists the initiation of sliding motion between two surfaces, while kinetic friction is the force that opposes the motion once the surfaces are sliding.

Step 2: Comparing coefficients.
The coefficient of static friction is generally higher than the coefficient of kinetic friction because it requires more force to initiate motion than to keep an object in motion.

Step 3: Conclusion.
Thus, the correct answer is that the coefficient of static friction is more than the coefficient of kinetic friction.
