Question

Rolling friction is always greater than static friction.

• A. True
• B. False

Answer 1

The correct option is B False

Rolling friction: It is the frictional force that occurs when one object rolls on another.

A diagram to represent rolling friction:

Static friction: It is the frictional force applied to an object at rest.

A diagram to represent static friction:

1. Rolling friction is always less than static friction.
2. The frictional force is proportional to the area of contact between the two bodies.
3. Rolling friction is weaker than sliding friction because the area of contact is less in rolling friction.

Hence, rolling friction is always greater than static force.

Therefore, the given statement is false.
