Friction is the force that works against any action. say a ball is moving on the ground, it is friction that work against the direction of the ball which helps it to roll farther. so it is a evil that work against our actions but its necessary in order to complete them
or
Without friction we cannot set out the bodies in motion or stop the moving bodies. Thus friction is absolutely necessary for carrying day to day activities. On the other hand, it also wastes the time and energy, brings about wear and tear and slows down the motion. Thus, we can say that friction is a necessary evil.
