Mention few methods of reducing friction.
Answers
We can reduce friction by methods such as :-
1)using lubricants substances such as oil they are the substance that reduces friction for various uses.
2)using ice makes the friction less because of its slipperiness when anyone walks there is very less friction.

Answer:
Methods for Reducing Friction
☆ Moving parts of machines are covered with oil or grease, which make the effect of friction less.
☆ The surfaces are highly polished, to eliminate the irregularities thus making the surface smooth and reducing friction to a great extent.
☆ Fluid friction is reduced by using streamlined shapes in airplanes or ships.
☆ Use of wheels between surfaces moving over each other reduces friction as rolling friction is less than the sliding friction.
☆ Ball bearings are used in machines to reduce friction. These are tiny steel balls often placed between moving parts of machines which reduces friction and saves a lot of energy.
