Question

State two methods to reduce friction

Answer 1

Answer:

add powder:

lubricants

ball bearings

objects should be streamlined

Answer 2

Explanation:

Friction depends on Normal

F = mew (s) × N

where s is static friction.

So mew(s) is different on different places.

So you can use smooth surface

Eg : Oily surface.

You can reduce normal, By applying force on an angle.
