Friction is a necessary evil. Without friction, we cannot walk, hold articles, the brakes of automobiles do not work, and the power of a motor cannot be transferred to a grinding machine. However, friction is undesirable in certain cases and we need to reduce it. For example, In the manufacturing industry, machinery parts tend to wear out because of friction. Some machines may even start consuming more fuel because of this reason. Therefore friction needs to be removed. But removing friction completely is not possible; it can only be minimised.
