Question

Friction is both good and evil how can you Say

Answer 1

As if the friction is more it's good as we can walk ,write etc..
But if it is very less lyk on wet floor we can't walk properly there r chances of falling...

Answer 2

Hi friend,

Friction is a evil as well as a friend.

FRICTION IS A FRIEND-:

•Friction between our feet and the footwear and the ground helps us to move without slipping.Thats why it's difficult to move on a highly polished surface or on ice.

•The friction between the treaded tyres and the rough surface od the road enables vechiles to move safely on the road.Thats why we observe more incidents of vechiles skidding on greasy or wet roads on rainy days.

•Friction between the brake shoe and the wheel slows down or stop the moving vechile.

•Friction between a pencil or a pen and paper helps us to write.That is why we find it difficult to write on smooth surfaces like plastic,glass,etc.It is friction which allows our teachers to write on the blackboard as it is rough.

•We are able to light a matchstick,sew clothes,tie a knot or fix a nail on the wall because of friction.

FRICTION IS A EVIL-:

•Friction wears out the rubbing surfaces like screws and ball bearings of machines of machines or soles of shoes.

•The objects in contact require more force to overcome friction between their rubbing surfaces.This results in wastage of energy.

•We know that friction produces heat.This heat raises the temperature of a machine,sometimes causing a hgreat damage to machine parts.Hence,proper arrangements have to be made to keep machine cool.For example, insulation of windings of machines like mixer grinders,hair dyers,etc. may get spoiled due to friction and the motor may burn.
