Question

The maximum force of friction which just allows one body to slide upon another body is called ....................... .

• A. static friction
• B. kinetic friction
• C. limiting friction
• D. all

Answer 1

The correct option is C limiting friction

The maximum force of friction which allows one body to slide upon another is called as limiting friction.

Friction is caused due to interlocking of irregularities present on the surface when two bodies are in contact. Force is required to unlock these irregularities between two surfaces of a sliding body. Thus limiting force is slightly more than the dynamic friction. Thus the force at which the body just slides over one another is called as limiting force.
