Question

how can we reduce friction? why do we need to do so? in two lines​

Answer 1

Answer:

We should reduce friction by

1. Greasing
2. Oiling
3. Making the surface plane and smooth .

Answer 2

Answer:

There are a number of ways to reduce friction:

1.Make the surfaces smoother. ...

Lubrication is another way to make a surface smoother.

2.Make the object more streamlined.

Reduce the forces acting on the surfaces.

3.Reduce the contact between the surfaces.

4.Roll the bodies instead of sliding them.

• because Friction is a necessary evil which causes a lot of wear and tear in machine parts that move against each other. It erodes the surfaces and destroys their symmetries. Hence, in such cases it is desirable to reduce friction. Friction is reduced by lubricating surfaces to decrease the friction.
