Question

what are the different method to reduce friction​

Answer 1

Answer:

Explanation: There are a number of ways to reduce friction:

• Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.

• Lubrication is another way to make a surface smoother.

• Make the object more streamlined.

• Reduce the forces acting on the surfaces.

• Reduce the contact between the surfaces.

• Roll the bodies instead of sliding them. If they are flat attach wheels on them.

Answer 2

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.
