Question

Write three ways to reduce friction with examples​

Answer 1

Answer:

Three ways to reduce friction are:-

1) Using lubricants

Examples- In door hinges, in other machineries

2) By having streamlined body

Examples- In dolphins, aeroplanes, etc.

3) Having smooth surfaces

Examples- Glass, tiles,etc.

Answer 2

● Polishing the rough surface.

● Oiling or lubricating with graphite or grease the moving parts of a machine.

● Providing all bearings or wheels between the moving parts of a machine or vehicles reduce friction and allow smooth movement as rolling friction is less than sliding friction.
