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: Frictional Forces Defined.
Frictional forces encompass static, sliding, rolling, and kinetic types. Limiting friction is the maximum frictional force that opposes motion right before an object starts to slide.Step 2: Conclusion.
The frictional force present when an object is on the verge of moving, but not yet sliding, is the limiting friction. This represents the highest possible static friction before movement initiates. Final Answer: \[ \boxed{\text{Limiting frictional force}} \]
