Friction is not necessarily an evil, but rather a natural force that arises when two surfaces come into contact. While friction can sometimes be seen as an obstacle or source of resistance, it is also essential for everyday tasks such as walking, driving, and writing. Without friction, it would be difficult to move objects or maintain traction, posing safety risks and making many activities impossible.

Advantages of friction a necessary evil?
Friction is advantageous because it allows us to walk, drive, and grip objects. It also helps in various industrial processes like cutting, grinding, and polishing. However, it is considered a necessary evil because it can cause wear and tear on surfaces, reduce efficiency in machines, and generate heat or noise.
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.
Why is friction a disadvantage?
Friction is a disadvantage because it causes resistance and reduces the efficiency of motion in various mechanical systems. It generates heat, causes wear and tear on surfaces, and can lead to energy loss. Minimizing friction is essential for improving performance and reducing the negative effects associated with it.
Why is friction a nessary evil?
Friction is necessary because it helps objects stay in place and allows us to walk, grip objects, and drive vehicles. However, it is sometimes considered a "necessary evil" because it can also create heat, wear out machinery, and reduce efficiency in various processes.
What are the 2kinds of friction?
The two types of friction are static friction and kinetic friction. Static friction occurs when two surfaces are at rest relative to each other, while kinetic friction occurs when two surfaces are in motion relative to each other.
Why is friction called a evil?
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.
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 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 the evil of all motion?
Friction is often seen as a hindrance to motion because it opposes the movement of objects by creating resistance. It can slow things down, decrease efficiency, and cause wear and tear on surfaces in contact. While friction is necessary for many everyday actions, excessive friction can be considered undesirable in some situations where smooth, unhindered motion is desired.
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.
