Question

6. Two methods of reducing friction​

Answer 1

Answer:

Here is your answer.

Explanation:

• By using lubricants: friction increases as the roughness of the surface increases. ...
• Polishing surfaces: It makes the surfaces even and hence reduces friction.
• By using ball bearings: Rotating machines can be mounted on ball bearings. ...
• By streamlining: streamlining reduces the area of contact and thus reduces friction.

Answer 2

Answer:

1. by lubrication or oiling

2. by using wheels ( which can help in rolling) (as rolling friction is less than sliding friction)
