Answer 2

friction as a friend:;

it helps to fix a nail in wall it helps to hold a pencil between our fingers we walk on ground due to friction cars and automobiles move on the ground due to friction it helps in construction of buildings it helps in placing an object at one place                                                                                                                                                     friction as a foe:                                                                   friction is un desirabe in machinary as it is the cause of wearing out of parts it also incresas the heat in machinary which also causes seveere damage it.


Frictional force is the force that opposes the motion of an object and arises due to contact between two surfaces .Friction is a friend because we are able to walk on the ground normally due to friction between our feet and the ground . we are able to write on a paper with a pencil due to friction .Friction is a foe because it causes damages to machines . It causes wear and tear . It causes wastage .

We able to walk due to friction. If there is no friction we are not able to walk. We always get slip down. For ex: we slip over banana because others is no friction it.

Friction is friend- Friction help in walking, driving, holding, writing etc. Harms of friction- 1) Wear out the tyres of vehicles and soles of shoes. 2) Production of heat in machines causing damage.
