Question

friction is necessary or evil .comment ​

Answer 1

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.

Friction is said to be a necessary evil because it is useful as well as harmful. friction helps us to walk, write, hold things, lift objects. So it is necessary in our lives. Without friction many essential processes can not be done.
