Question

Explain four methods by which friction betweent two should

surfaces in contact can be reduced.​

Answer 1

Answer:

The four methods by which friction between two solid surfaces in contact can be reduced are: By polishing – Polishing a rough surface smoothens it and reduces the friction. By lubrication – Lubricating the surface with oil, grease or graphite decreases the friction between two surfaces

Answer 2

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.
