Answer 2

$\mathcal\red{Answer}$

⟹ 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.
