Answer 1

αηsωєя⛄࿐

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

Answer:

Force

Explanation:

It is because if we apply force on the opposite direction, friction will reduce

Same way if we make the Surface Rough, Friction will reduce
