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 are the two factors that affect the friction force between two surfaces?
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.

What is a meteroroid called when it hits earth?
A meteoroid is called a meteor when it enters Earth's atmosphere and creates a streak of light in the sky due to the heat generated by friction. If any part of the meteoroid survives the journey and hits the ground, it is then considered a meteorite.

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.
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?
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.
Is friction necessary for motion?
No. Friction is just necessary for controlling motion.
