Friction or frictional force help us do work in many ways like walking,writing and more. There are some Advantages and disadvantages of Friction .

Aviral jain part 2
we can't move without friction between our legs and ground or writing with a pencil requires friction. We can't hold a pencil without friction now I will tell you some disadvantages of friction. The main disadvantage of friction is that it produces
heat in various parts of machine
NOW WE ALL CAN SAY THAT FRICTION IS A NECESSARY EVIL
THANK YOU

Frictional force or friction is the force between two objects which are in contact with each other. friction always works in   the opposite direction of motion. The advantages of friction are that it helps us to walk, Run, ride and Drive etc .The disadvantages of friction are -it opposes the motion ,it produces noise from the Machines ,engines and automobiles need more fuel so there is a money Loss therefore friction is a necessary evil....

Friction is very much necessary in our lives as it helps us to walk,run ,write etc.But it has some disadvantages too.
DISADVANTAGES OF FRICTION
1-it produces heat in machines and some of the energy is wasted in the form of heat .Eg. friction is created between the tyres of a car and heat is produced but it can overheat and damage the tyres.
2-due to friction noise is produced in machines.
ADVANTAGES
1-it helps us to walk. Without friction we will not be abel to walk.
2-it helps us to write . Without it we cannot even hold a pencil.

THAT PROVES FRICTION IS A NECESSARY EVIL.....

You need friction and there are many uses for friction but it has many disadvantages too . You can run but  but if the ground was all grass you could dis balance and fall .. like this boy is trying to skate on a snowy ground we cant probably all but the other boy will not stay or long .any moment he can fall . we can really say that friction is a necessary evil ..

Without friction we will not be able to walk, run, write etc. But too much friction will cause many loses.
DISADVANTAGES OF FRICTION:
1- The main disadvantage is that it produces heat in various parts of machines and causes heavy loss of energy takes place.
2-Due to friction noise is produced in various parts of machines.
ADVANTAGES OF FRICTION:
1-WALKING- Without we will not be able to walk.Friction is a must .
2-WRITING-We will not be able to hold pencil without friction.
ITS TRULY SAID THAT FRICTION IS A NECESSARY EVIL..........

Friction is the force that works against any action,meaning it opposes motion . In our life we drive, apply brakes, pull objects etc. We are able to do all the things because friction is there.
Friction has many advantages and disadvantages.
Some of the advantages are:-
1] It helps in walking , running and standing.
2] It helps us to write.
Disadvantages are:-
1] It produces heat in machines  and some energy is wasted in heat energy.
2] Due to friction noise is produced in machines.

To reduce friction lubrication is done in machines .
Thatswhy friction is a necessary evil.

As we know we cannot live without friction as friction plays very important role in our life.But it has some  advantages and disadvantages  also. I will tell you some. Some advantages are we can not move without friction

Frictional force stops or slows down the speed of an moving object . It helps us to walk , run, write,drive etc. As it has many advantages it has some disadvantages also like it creates noise and heat in various parts of machines , it opposes the motion  etc. There are several ways to reduce friction like lubrication , oiling etc. Anyways friction is a necessary evil.

So? Where was I? OH YEAH! Friction helps us to walk, run etc but, IT CAN BE DEMONIC 😈.

Friction sometimes is a necessary evil. I mean, don't get me wrong, It's useful too! It helps us to walk, run, write et

Frictional force is a force when two objects are in contact with each other. There are some advantages of friction , e.g. it helps us to walk, write  etc. There are some disadvantages also like it opposes the motion , it leads to wastage  of both money and energy .

Frictional force or friction is the force between two objects which are in contact with each other. It always works in the opposite direction or motion.The advantages of friction are that it helps us to walk,write,driving car etc. But it has disadvantages like it opposes the motion,it produces noice in machines.But in anyways friction is a necessary Evil
