Ans 3.
1.Friction helps us to write-Because of the friction in the blackboard the particles of the rub off we are clearly able to see what is written in the blackboard.
2.Friction helps us to walk because if the surface of the floor is smooth we will slip.
3.Friction even helps our cars and bikes to run easily.And if friction is not there our cars will run on the road and an accident might occur.
These were the points I knew.Hopefully it helped.
