Question

mention and explain the methods of reducing friction in ncert syllabus​

Answer 1

Answer:

exaplain the methods of reducing friction

there are a number of ways to reduce friction ;

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 surfacesurfaces

Answer 2

Answer:

By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
