Question

Explain that how can we reduce the friction?

Answer 1

$\huge{\underline{\underline{\boxed{\sf\red{Answer\:༉}}}}}$

There are various ways to reduce friction:

1. By using lubricants: friction increases as the roughness of the surface increases. Lubricants fill the fine pores and gaps between contact

surfaces and reduces friction

2. Polishing surfaces: It makes the surfaces even and hence reduces friction

3. By using ball bearings: 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..
