Question

write 2 methods of reducing friction?​

Answer 1

What are the methods of reducing friction ? Explain

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

Friction can be reduced in a number of ways:

Explanation:

• Friction increases as the roughness of the surface increases when lubricants are used. Lubricants minimise friction by filling the small pores and crevices between contact surfaces.
• Polishing surfaces: This evens out the surface and so lowers friction.
• Using ball bearings allows you to: Ball bearings can be used to support rotating equipment. The friction of rolling is less than that of sliding.
• By streamlining: streamlining minimises the contact area and consequently friction.
