Question

How to reduce friction ?​

Answer 1

Answer:

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

Explanation:

there are various ways to reduce friction

1.by using lubricants : friction increasesb. lubricants fill the fine pores and gaps between contact surfaces and reduces friction

2. polishing surfaces even and hence reduces friction

3.by using ball bearing: rotating machines can be mounted on ball bearings. rolling friction is lesser than sliding friction

4.by streamlining: streamlining reduces the area of contact and thus reduces friction
