Question

write 2 methods of reducing friction?



Bhai itna bda answer bhi nhi chaiye ​

Answer 1

Answer:

By using lubricants: friction increases as the roughness of the surface increases. ...

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

Explanation:

hope it helps you

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.
