Question

how to increase in friction​

Answer 1

Answer:

by increasing Rough of the surface .

Explanation ..

To increase friction---->>

the surfaces in contact have to be made rough. The two surfaces in contact can also be pressed harder to increase force between them. Use of adhesive materials that stick surfaces , also increases friction between them...

Answer 2

There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the 'designs' that you can see on the tyre surface), which increase the friction between the tyre and the road.

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
