Collect at least six objects of different materials. Check them for their friction
by sliding an object on their surfaces. Now arrange them according to their friction
(high to low). How their friction can be reduced? Suggest some methods according to the materials.

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
