Hey❤️
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.
