Question

Collect at least six objects of different materials. Check them for their friction
by sliding an object on their surfaces. Now arrange them according to their friction
(high to low). How their friction can be reduced? Suggest some methods according
to the materials.
can anyone answer me ?​

Answer 1

Explanation:

Methods for decreasing 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.
