Question

Describe how friction can reduced.In what way will it help if friction is reduced?

Answer 1

Answer:

Friction is reduced by polishing the surface, as polishing makes the surface smooth. 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:

Methods used for Reducing Friction

Friction is defined as the resistance experienced by the surface or by an object when it is moved over the other. Following are the different methods that are used for reducing the friction:

• 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.
• Friction is reduced by polishing the surface, as polishing makes the surface smooth.
• 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.
