how can we inscrease and reduce friction ? pls answer in points
Answers
Answer:
1.Create a “rougher” or more adhesive point of contact.
2.Press the two surfaces together harder.
3.Stop any relative motion.
4.Remove lubrication between the two surfaces.
5.Remove wheels or bearings to create sliding friction.
6.Increase the fluid viscosity.
1)Friction can be reduced by making the surface smooth by polishing.
2)Friction can be reduced by applying lubricants (like oil or grease) to the rubbing surface.
3)Friction can be reduced by using wheels to move objects.
4)Friction can be reduced by using ball bearing between the moving parts of machine.

Answer:
(i) Friction between two surfaces can be decreased by using lubricants. (ii) Friction between two surfaces can be reduced by polishing them. The interlocking and projections are minimized by this method. (iii) The friction due to air is reduced by making the automobiles streamline.
