Question

5. 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.​

Answer 2

Answer:

Have you ever tried to get a running start and slide across a smooth, wooden floor while wearing socks? What happens if you try the same thing on a carpeted floor or while wearing shoes? The amount of friction between your feet and the floor surface determines how well you can slide. Some combinations of surfaces, such as socks on a wooden floor, produce very little friction. Other combinations, such as rubber soles on a wooden floor, produce much more friction. In this project you'll do a much smaller-scale friction experiment by launching tiny objects along a surface with a rubber band.
