Answer 1

Answer:

Friction is a necessary evil acting both as a friend and a foe. Examples of friction as a friend: We are able to walk because of frictional forces between ground and our feet. We are able to write because of friction between ball point and the paper surface.

Frictional force causes a lot of losses in general upkeep and wear and tear of machinery. ... But almost all crucial tasks cannot be carried out without the presence of friction. Basic activities like walking and writing on a surface are possible due to friction. Hence it is considered as a necessary evil .
