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
Why is friction called necessary evil?
Friction is called a necessary evil because we cannot completly avoid it an actually it is used in many cases.
Why is friction a nessary evil?
Otherwise we cannot type on key board and move the mouse as wanted.
What are the 2kinds of friction?
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.

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.
Prove that friction is a necessary evil?
Yes necessary evil. If friction is totally absent then no wheel could roll on the road. No chance of walking on the floor. We cannot hold even the pen. Same time too much of friction would bring a terrible loss of energy.
How is friction an evil?
Friction makes us hard to walk on slopes, it wears out the materials whether they are screws, ball bearings or soles of shoes. Friction also produces heat.
Why is friction the evil of all motion?
Friction is what takes energy away from motion. If there was no friction, it would take a lot less energy (gas, fuel, electricity) to move things.
Why is friction called necessary evil?
Friction is called a necessary evil because we cannot completly avoid it an actually it is used in many cases.
Why friction is a necessary evil?
because we cant walk , hold articles , we cant write and the construction of house is impossible. but there are some disadvantages in friction.
Why is friction a nessary evil?
Otherwise we cannot type on key board and move the mouse as wanted.
How the friction is called somewhat evil in our life?
Because it takes all the F=μN out of our lives! F- Force in Newtons (N) μ - Greek letter Mu (Coefficient of friction with no units) N-Normal force (force perpendicular to surface measured in newtons N) (found using mass * gravity assuming you're on a flat surface) When a surface has a lot of friction, the force applied is lowered due to the higher friction coefficient. When there's more friction, it takes more force to move an object on a surface.
What are the 2kinds of friction?
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
