Question

How can we increase the frictional force?

Answer 1

$\underline{ \underline { \bold{Friction}}}$

The force which always opposes the motion of one object over another object in contact with it, is called friction.

Friction between two surface depends on two factors:

• The force with which two surfaces are pressed together.

• The nature of the two surfaces ( smoothness or roughness)

☆ How can we increase the frictional force?

⇒ Methods of increasing friction:-

• Spikes are provided in the shoes of players and athletes to increase friction and prevent slipping.

• Machine belts are made of special materials to increase friction and drive machines wheels properly.

• Grooves are made in shoes to increase friction and prevent slipping .

Answer 2

Answer:

By using rough surfaces.

Explanation:

As frictional force stops or slows an object when two surfaces are touching each each other.
