Dear Milad
You must specify your application. For example, with no friction we can not even move.
on the other hand, friction slows many processes and adds limitations.
Dear Milad Sakkaki,
It depends on the case you are talking about, but as I know of course it is not useless, as it has many applications. One of the simplest examples is that if there were no friction, we wouldn't be able to walk and shoes just slipped! Also almost all fastening devices rely on frictional forces to keep them in place once secured, examples being screws, nails, nuts, clips and clamps. But there are some disadvantages related to the presence of frictional forces, which I think the most important can be the energy waste.

Dear Milad
Of course it can be useful. movements occur by friction but in general you should explain more your working condition
Dear milad
It depends on the conditions. In some cases it is useful like walking and in some cases it can be harmful.
Dear Milad Sakkaki
it may be useful or not. it depends on your case. for example, friction helping cars stop when the brakes are applied or friction produces heat causing wastage of energy in machines.
Dear Milad Sakkaki
Friction is useful in some cases and harmful in some cases, it is depending on the application.
Dear Milad,
Friction can be useful. For instance:
1.friction between our shoes and the floor stop us from slipping
2.friction between tyres and the road stop cars from skidding
3.friction between the brakes and wheel help bikes and cars to slow down
