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.
