Some points are given below which show that friction is both a friend and a foe: 1) Friction as a friend: It allows us to grip and catch any object. It helps us to walk comfortably on the floor. It helps to minimise the speed or to stop any moving object. It helps us to write. 2) Friction as a foe: It causes wear and tears in objects. It causes damage to the parts of machines and tools which further require money to get them repaired. It reduces the speed of moving objects, so more force is required. It produces hurdles in moving any object freely.
