An example of unuseful friction is when trying to push a heavy object on a rough surface where the friction makes it difficult to move the object smoothly.
Friction can be unuseful when trying to achieve smooth motion in machines or when trying to move heavy objects. It can generate heat and cause wear and tear, leading to inefficiencies and increased energy consumption. In certain applications, such as in some precision instruments or machinery, reducing friction is desirable.
An example of a non-frictional force is gravitational force. For example, when an object is in free fall, there is no friction acting on it.
A example of friction is rubbing your hands together the heat you feel is friction. Oh dont be a shat head.
A piece of sand paper on a piece of wood is an prime example of rubbing friction.
In situations where smooth, frictionless motion is desired for efficiency, such as in industrial machinery. In sports where reducing friction can improve performance, such as in ice skating or surfing. In precision equipment like microscopes or telescopes, where friction can cause inaccuracies in measurements or observations.

The question is Why is internet useful? not why internet is unuseful. I cant find the exact answer if the internet is unuseful to you.
this answer was decided that it was unuseful and you should look at another answer.
Whenever you were trying to reach high speeds or conduct exact experiments where friction would slow something down or cause heat. For example, friction is extreamly "unuseful" when spaceshuttles are re-entering the atmosphere because the friction of the spacecraft and the air create incredibly height temperatures. Special heat plates were invented to absorb this heat. If they fail, like in the re-entry of the Columbia Space Shuttle, the shuttle will be completely destroyed.

An example of fluid friction is the air resistance felt by an airplane.

Rolling Friction, Static Friction, Sliding Friction, & fluid Friction

YES
Dams are very useful
like peanut better
