# How is a friction is a necessary evil?

it can cause sparks which may result to fire

It is due to the existence of friction that we can walk on the ground, trains can run on rails, buses can ply on the ground.In the absence of friction we cannot hold a pen or stop our vehicle.Nails and screws join two surfaces due to the force of friction.Without friction it is impossible to climb on the tree or fix a nail on the wall.In fact life is impossible if there is no friction in nature.So friction is a necessary evil.

friction is a evil as it causes much loss of valuable energy needed to overcome friction which can be put to other use.but it is at the same time necessary as life is not possible without friction

so why it is necessary evil?

FRICTION IN DAILY LIFE

• It would be impossible for us to walk without friction. It is because of friction between our feet or shoes and the ground that we are able to walk by pushing our feet against the ground. Without friction, we would slip as soon as we tried to walk. It is very difficult to walk on ice or on a smooth surface is very little.
• Cars and buses are able to move safely on the road because of friction between the treaded tyres and the surface of the road.
• It would not be able on paper without friction between the pencil or pen and paper. Neither could your teacher write on blackboard.

·  Friction Causes wastage of energy. This is because any object that moves, has to overcome the force of friction.
·  Friction wears of the rubbing surfaces. The soles of our shoes wear out in few months due to friction. The moving parts of a machine wear out with time because of friction.
·  Friction generates heat. Sometimes this can harmful. The heat produces in a fast moving machine is very high. Proper arrangements have to be made to cool the machine, otherwise it can get damaged. If the cooling arrangement in a car does not work properly, the engine can get damaged.

friction is wasteful. it causes loss of energy and causes wear and tear of machines.but, on the other hand, our normal daily life would not be possible if there were no friction.........

Isn't it good that we have small explanation to understand it. Afterall they all makes us understand what are these. Once we understood them, we can strech it. Simple!!

Friction is necessary:

1. To walk, To drive a car, roll.

2. To control speed of vehicles, bouncing balls.

3. To operate screws, blots, harnesses, writing.

4. To have a nature free from violent storms, tsunamis, noise and chaos.

Friction is evil:

1. It wastes a lot of energy, decreases efficiency of vehicles.

2. It generates heat and destroy machines.

4. All forms of motion in contact with other bodies needs a constant force and thus work is done at every step.

5. For physicists it increases the complexity of calculations.

hi!friction is both a friend and a foe.it helps in following ways:

1)it helps in gripping.

2)it helps us to walk.if there was no friction we would never stop once we set into motion.

3)it helps us to write on paper or any other thing.

friction is a foe for following reasons:

1)it is responsible for the wear and tear of machines.

2)it reduces the speed of a moving object.

3)it is responsible for the wear of soles of shoes.

hence it is a necessary evil.cheerssss

Friction can be considered both friend as well as foe.

You are able to walk because of friction. If there had not been friction, you would have slipped all way, and you won’t be able to stop anywhere. Some of the very basic activities are possible only because of friction.

At the same time, it is friction which causes wear and tear to our machines. Moreover we need to apply a huge amount of energy to overcome friction in various parts of machine.

Considering all these factors friction can be called a necessary evil!!

Hope it is clear to you!

friction are necessary for moving .
without friction we cannot move.
or walk .
friction are also needs to vehicle.

Write your project inbig handwriting and if still its less then use ur brain to add some points. Dont just rely on meritnation for everything. Meritnation is a tool for learning not for copying down projects and assignments. Im not roasting u but im just guiding u.hope u understand😊

yes friction is necessary evil because it has both advantages and disadvantages advantages: 1 without friction we can not eat without friction we can not write and much more disadvantages wear and tear of shoes and clothes . it reducues the efficiency of proper selction of materials.

Necessary
1) it helps many things to move and also to stop.

Evil
2) it causes an uneccesary heat whent it is being applied by a rough surface

Force of friction brings about wear and tear in moving bodies . It produces heat and slows down moving bodies . A lot of energy is wasted in overcoming friction. However, if there were no friction, the bodies would either slip or it will not move. Furthermore moving bodies will not stop . Even walking on the surface of earth would have been impossible. Thus, we can say that force of friction is a necessary evil

Friction is necessary because 1. It allows us to walk properly on the ground. 2. It allows us to grip and catch different objects. 3. Things don’t move from their place due to friction 4. Speed of moving objects can be controlled using friction 5. It helps us to write on paper and on blackboard. Friction is an evil because 1. Friction causes wear and tear of objects. 2. Regular maintenance of moving objects( machines and tools ) wastes a lot of money 3. It makes the movement of heavy objects very difficult 4. It causes damage in the parts of the machine 5. It does not allow free movement of objects.

Friction is both necessary as well as evil due to it has advantages and disadvantages respectively

This is a very relevant theoretical question. Friction is responsible for opposing the motion of the body and without it the body would not stop because the body will not lose it's kinetic energy. Friction is not only present in rough surfaces but also in air in water and any other matter.
It is simply necessary because obviously without it walking ,driving and flying would be very difficult.
It maintains the grip on the ground.
But Why is it called evil?
It is simply because it is very troubling when it's magnitude is large. Moving sometimes require excessive energy.
For example on deserts and snowy regions where friction is very large.
These were my views to your question.
Hope it helps.
