Question

mention the methods used to decrease 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.

Explanation:

Answer 2

Explanation:

1. make the surface smoother

2.lubrication is another way to decrease friction

3. make the object more streamlined.

4. reduces the forces acting on the surfaces.

5.reduce the contact between the surfaces.
