Q. Which of the following kinetic friction is smaller?

  • (A) limiting friction
  • (B) static friction
  • (C) rolling friction
  • (D) sliding friction
💬 Discuss
✅ Correct Answer: (C) rolling friction
Explanation: the force which comes into play when a body rolls over the surface of another body is called rolling friction. for the same magnitude of a normal reaction, rolling friction is always greater than the sliding friction.
