Example to show that friction is both a five friend and a foe​

Examples to show that friction is a friend and a foe: Friction is friend: (i) Friction allows us to grip and catch different objects. (ii) It helps us to walk comfortably on the surface. (iii) It helps to minimize the speed or to stop the moving objects.

Hope it helps :)

Have great Day
