Question

What is the force of friction ? write any two method to reduce friction​

Answer 1

Answer:

By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.

Answer 2

Explanation:

the force required to initiate or to maintain relative motion against friction.

To reduce friction.

1. by using lubricants. friction increases as roughness of the surfaces increases

2. polishing surface. it makes the surface even and hence reduce friction.
