Some points are given below which show that friction is both a friend and a foe:

Friction as friend:

  • It allows us to grip and catch any object.
  • It helps us to walk comfortably on the floor.
  • It helps to minimise the speed or to stop any moving object.
  • It helps us to write.

Friction as foe:

  • It causes wear and tear in objects.
  • It causes damage to the parts of machines and tools which further require money to get them repaired.
  • It reduces the speed of moving objects, so more force is required.
  • It produces hurdles in moving any object freely.
