    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.

    In this platform we deal with conceptual explainations and therefore instead of a story on "Friction as a necessary evil" I provide you with below conceptual solutions. (i)- Friction is a necessary evil. (ii )- There are instances in daily life where friction is a necessity. (iii )- Without friction, we cannot hold objects in our hands, we cannot walk and we cannot light a matchstick, we would not be able to apply brakes in the moving vehicles etc (iv)- Friction has both advantages and disadvantages. (v)- And therefore, eventhough friction obstructs the intended motion, it is infact very important in daily life.
