Question

More irregularities on the contact surfaces mean more friction.

• A. True
• B. False

Answer 1

The correct option is A True

1. The frictional force is a contact force that acts between two surfaces in contact.
2. At microscopic levels, even a smooth-looking surface has irregularities that cause friction.
3. These irregularities get interlocked and oppose the motion of the object.
4. For example, groves are created on tires to increase friction between vehicle and road.
5. Therefore more irregularities on the surface will cause more friction.

Hence the given statement is true.
