Is friction a necessary evil? Explain.


#2

Yes, indeed friction is a necessary evil. It’s because of:

  • Without friction between the feet and the ground, it would not have been possible to walk.

  • The tire of the motor cars and cycles are rough to increase the friction.

  • In absence of the friction, the brakes of the motor car won’t work well.
