Question

Article Writing On Friction is the necessary evil.

Answer 1

hi friend
here your answer looking for

I will glad to discuss about this topic"friction is necessary evil"

so let's first understand what is friction?

Friction :- friction is a opposing force and relative force that opposes motion.
or in other word we can say that friction is force that opposes any kind of motion that is in the contact of any body.

so you might be thinking how this friction cause:-

if we observe any body, then we will find that it must have some irregularities on its surface.
so these irregularities get interlock between each other when there is a motion that is in the contact of that body.
and this interlocking causes the opposing force or opposes the motion.

hope you had understand what is friction and what is the cause of friction.

so you must be heard that friction is a necessary evil.

why we call so? 
what is the reason behind this?

so in order to give your answer let's first know what is the meaning of necessary evil.

necessary evil means something that is very important but sometimes causes problem also.

similarly the friction is also a necessary evil that means it is very very very important but sometime causes some problems.

show the friction has advantages as well as disadvantages as follow and because of these advantages and disadvantages it is known as the necessary evil.

Advantages :-

1). because of friction only we are able to walk. because when we are walking then we are pushing our leg to the ground and because of the friction we pushes forward.

2). because of the friction only we are able to write.

3). and the friction is only reason by which we can grab anything or put out anything.

4). even because of friction only we are able to fix the nail.

5). if there will be no such kind of opposing force then they will not able to sit also.

6). because of friction only we are stable and so many things are stable.

7). even the brakes of vehicle is also because of the friction only.

Disadvantages:-

1). the friction causes the loss of energy.

2) when there is a friction then there is a amount of heat that is generated so this causes the waste of heat energy.

3) even in pushing something it will be much easier to push when there will be less friction.

4) this causes wear and tear.

so because of the above advantages and disadvantages the friction is known as the necessary evil.

hope you had understand what is friction, what is the cause of friction and why it is known as the necessary evil?

Answer 2

yes friction is nessary evil some times we need low friction but at the same time we got suddenly extremely high friction for eg
we are doing sking on the ice suddenly comes water we fall down why because we are going to low friction is shifted to very high friction
so thats why friction is nessary evil.
