Answer 2

Following are the different methods that are used for reducing the friction:

1)For objects that move in fluids such as boats, planes, cars, etc, the shape of their body is streamlined in order to reduce the friction between the body of the objects as the fluid.

2)By polishing the surface, as polishing makes the surface smooth and friction can be reduced.

3)Using lubricants such as oil or grease can reduce the friction between the surfaces.

4When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
