Question

Explain the desirable factors of friction​

Answer 1

Friction is Desirable: A friction is very much desirable to stop the body from its moving condition. ... If the friction is more between the block and inclined surface, then a large force is required to push the block on the plane. Thus friction is desirable or undesirable depending upon the condition and types of work.

Answer 2

$Friction \: is \: Desirable$

A friction is very much desirable to stop the body from its moving condition. Suppose if there is no friction between the contact surfaces, then a body cannot be stopped without the application of external force. In the same time a person can't walk on the ground if there is no friction between the ground and our legs also no vehicle can run on the ground without the help of friction we can slip on it.
