Why is friction not necessary?
During solving the questions (In Physics) sometimes we consider the bodies frictionless but friction exists. : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : : sorry mom calling(:P)
Is friction necessary for motion?
No. Friction is just necessary for controlling motion.
Advantages of friction a necessary evil?
A necessary evil means that friction has advantages as well as disadvantages so it called as necessary evil. Advantages of friction areits helps us to walkto writedriving car, etc,
Why is friction a disadvantage?
Loss of energy. Any way friction is a necessary evil
What are the dangers of friction?
There are an unlimited number of dangers of friction. Friction can cause burns and sometimes unwanted fires in certain places.

No. Friction is just necessary for controlling motion.
Why is friction called a necessary evil?
Friction is necessary : If there is no friction between any two surfaces in contact, then the present day civilization will be no more- as we cannot even walk properly on the earth. There will be no fabrics and garments, no construction of buildings and no furniture, even no cooking and no vehicles. So friction is necessary. But too much friction causes a heavy loss of energy, wear and tear of machinery. Thus, the efficiency of machines will decrease tremendously. So, it is rightly said that friction is a necessary evil.

What parts of a bicycle is friction necessary and what parts are not necessary?
The bearings don't need friction, but everything else does. It there wasn't any friction it'd be impossible to bolt anything together.
How are friction and force related?
friction increases the amount of force necessary to do work
Why is friction a disadvantage?
Loss of energy. Any way friction is a necessary evil
In what ways can friction be helpful?
Friction is necessary for wheels to rotate and nails to keep in walls.
What are the dangers of friction?
There are an unlimited number of dangers of friction. Friction can cause burns and sometimes unwanted fires in certain places.
Does friction play a necessary role in a roller?
It keeps the roller down and creates friction to allow the roller to move.
What brings force to a stop?
sometimes friction
Does friction force things away?
not necessarily sometimes it creates force sometimes not
