Friction is a necessary evil. There are instances in daily life where friction is a necessity. 
Without friction, we cannot hold objects in our hands, we cannot walk and we cannot light a matchstick.

Friction plays a vital role in our daily life.

  1. Construction of buildings is possible only because of friction.
  2. We are able to write because of friction between the paper and the tip of the pen.
  3. Without friction between our shoes and the ground, we will not be able to walk.
  4. A horse cannot pull a cart unless friction furnishes him a secure Foothold.
