the very reason shoelace ties up b'coz of friction -if not the lace will not get tight at all and always be loose-
A shoelace is an example of a type of simple machine known as a pulley. The act of tying a shoelace involves using friction to create tension and secure the shoe, which is a basic function of a pulley system.

it's from a spongebob episode :D
Friction can be helpful and not helpful it is not helpful when you are running because it slows you down hope that'll help!!!! ;)
The pain that you fill on the top of your feet is caused by tying your shoelace too tight.
no, they untie because of the force and friction between them
Shoelaces generally have low friction, making them easier to tie and untie. This low friction allows them to slide through the eyelets of shoes smoothly without getting stuck.
Friction is helpful between car tyres and roads for grip. It is also sometimes used for heating as friction generates heat.
