Question

how we reduce friction?​

Answer 1

$\bold{answer}$

• 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

Answer:

by polishing the surface as polishing makes the surface mood and friction can be reduced using lubricant such as oil or grease and can reduce the friction between the surface when object are rolled over the surface the friction between rolled object and surface can be reduced by using ball bearing
