Friction of the skin against a surface can cause injuries.
Friction is the act and consequence of rubbing or rubbing against each other . This verb (rub) refers to lightly touching something or exerting minimal pressure on a surface.
For example: “The friction of the fabric of my pants on my skin caused me a blister,” “Because of the friction against the wall, I dirty my white shirt,” “Be careful with the friction of your hand on the paper because you can smudge the paper.” drawing" .
Before entering fully into establishing the meaning of the term, it is important to determine its etymological origin. In this case, we can say that it derives from the Latin ruptiare , which in turn comes from the verb rumpere (translatable as “like breaking into pieces” or “breaking” ).
Vehicle Friction
Friction can develop in different ways and in different contexts.
The friction of two vehicles on public roads, to cite one case, implies a minor traffic accident . It is not a crash since the impact is slight, but the friction can be enough to scratch the sheet metal of the vehicles.
a type of force
The idea of friction force refers to the force that acts when two surfaces are in contact. A distinction can be made between the static friction force (which acts in opposition to the beginning of sliding ) and the dynamic friction force (acts in opposition to the movement). The origin of the friction force is found in the small imperfections that exist on the surfaces that are in contact.
It should be noted that, when friction occurs between two objects, the friction force is exerted parallel to the support surface .
A sexual practice is called friction.
Friction as a sexual practice
In the context of sexuality , the practice of rubbing the genitals on another person's body, without penetration, is called friction or frottage .
Friction can be used in very different ways, all of them with the aim of enjoying a certain intimacy with another person:
- As part of the so-called “foreplay” that takes place before intercourse.
- As a way to obtain sexual pleasure without having to have intercourse as such and that helps prevent losing one's virginity.
- -As a way to have sex safely, avoiding the possibility of pregnancy, since there is no penetration.
Friction of this kind can be done both naked and clothed and even not only with the genitals but with other parts of the body, such as the breasts, thighs, legs or hands, for example.
There are certain dances that are considered to encourage friction to a certain extent, since the dancers maintain close contact and their movements are charged with eroticism . We are referring to lambada and reggaeton .
Likewise, we must not overlook the existence of what is known as frotism , a paraphilia that leads a person to become aroused simply by rubbing their genitals against the body of another person without their consent.
