Friction- A boon or Bane against motion
Friction is a boon because of its advantages like:
When we walk, we push the ground backwards with one foot. According to Newton’s Third law, there is an equal and opposite force exerted by the ground. This force is exerted on a comparatively smaller mass i.e. our foot. So, acceleration is increases. Hence the other foot gets accelerated.
If there is no friction, we will slip and can’t walk.
Friction is a bane because of its disadvantages:
