friction is called a necessary evil because we cannot completly avoid it an actually it is used in many cases.

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.
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 called necessary evil?
Friction is often referred to as a "necessary evil" because while it can impede motion and cause wear and tear, it is also essential for many everyday tasks. Friction provides traction for walking and driving, allows us to grip objects, and is crucial for many industrial processes. So, while it can be an inconvenience, it also plays a vital role in our daily lives.
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.
What is the friction of two objects that are moving called?
The friction is static friction.
What is the friction between moving particles called?
The friction between moving particles is called friction.
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.
What is the friction of two objects that are not moving called?
The friction between two objects that are not moving is called static friction. It is the force that resists the initial motion of an object at rest.
When an object rolls over a surface the kind of friction that occurs is called round friction.?
The friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is typically less than sliding friction because the object's motion is smoother and involves less resistance from the surface.
2 types of friction?
There is static friction, and dynamic (also called kinetic) friction.
What are 3 facts about friction?
1) friction thats lows things down is called dynamic friction 2) friction that stops things is called static friction 3) most of friction makes heat ( rubbing hands together )
