Question

The maximum frictional force which comes into play when a body just begins to slide over another surface is called

• A. Sliding frictional force
• B. Rolling frictional force
• C. Kinetic frictional force
• D. Limiting frictional force

Hint:

Limiting friction is the frictional force that resists the initiation of motion. Once motion starts, it becomes kinetic friction.

Answer 1

The Correct Option is D

Step 1: Define the frictional forces.
Frictional forces are classified into several types, including static, sliding, rolling, and kinetic friction. The maximum frictional force that resists the motion when a body just begins to slide is called limiting friction. Step 2: Conclusion.
When a body is about to move but hasn’t yet started sliding, the frictional force acting is the limiting friction. It is the maximum static friction force that can act before sliding begins. Final Answer: \[ \boxed{\text{Limiting frictional force}} \]
