Definition of friction
Friction refers to the action of rubbing (or when two things/body rub each other). Force
of friction means the force that opposes the motion of a surface
relative to another, or force opposed to that which is at the origin of
motion/move. The friction, as a force, occurs due to irregularities between contacting surfaces. These irregularities, even if they are only microscopic, generate an area of friction, called contact area.
It is possible to distinguish statistical friction, which is a resistance to be overcome in order to put a body in motion relative to one another with which it is in contact, dynamic friction, which is the constant magnitude opposing the movement once started.
Statistical friction takes place, for example, when an engine is not to be turned for a long time. On the other hand, the dynamic friction can occur with the action of the tires of a car when braking.
There is friction toys (better known under the name of 'toys rubbing') that mimic the behavior of certain vehicles, such as cars or trucks. The child must roll the toy (by dragging on the ground) backwards, so that the wheels can complete the mechanism of friction and take the momentum (in order to give an impulse). When the child loose the toy, said forces allow it to advance.
Figuratively, the friction (often in plural) means disagreements, clashes or the difficulties of both parties, either communities or people. For example: "friction between Jews and the Palestinians may lead to a new conflict of war."
In the colloquial language, this term (having friction or Miss friction) is linked to trade and dating (social relations).
