https://en.wikipedia.org/wiki/FrictionFriction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static

https://simple.wikipedia.org/wiki/Coefficient_of_frictionA coefficient of friction is a value that shows the relationship between two objects and the normal reaction between the objects that are involved. It is a value that is sometimes used in physics to find an object's normal force or frictional force when other methods are unavailable.. The coefficient of friction is shown by =.In that equation, is the frictional force, is the coefficient of ...

https://en.wikipedia.org/wiki/Friction_weldingFriction welding (FRW) is a solid-state welding process that generates heat through mechanical friction between workpieces in relative motion to one another, with the addition of a lateral force called "upset" to plastically displace and fuse the materials. Because no melting occurs, friction welding is not a fusion welding process, but a solid-state welding technique more like forge welding. Friction welding is used with metals and thermoplasticsin a wide variety of aviation and automot…

https://fr.wikipedia.org/wiki/Frottement- L'omniprésence des frottements a longtemps conduit à ce qu'ils ne soient pas considérés comme des interactions mais comme des caractéristiques fondamentales de la nature. Ainsi, dans la physique aristotélicienne, on considérait que les objets ne pouvaient maintenir leur mouvement que si une force continuait à s'exercer sur eux. L'observation des mouvements astronomiques, p…

För en kropp som påverkas av normalkraften N är friktionen given av sambandet F = μN, där μ är friktionstalet. Friktionen verkar i en riktning som är vinkelrät mot normalkraften.

Reibung – Wikipedia
https://de.wikipedia.org/wiki/ReibungReibung, auch Friktion oder Reibungswiderstand genannt, ist eine Kraft, die zwischen Körpern oder Teilchen wirkt, die einander berühren. Die Reibungskraft erschwert dann die Bewegung der Körper gegeneinander. Um eine Bewegung zu erzeugen oder aufrechtzuerhalten, ist Arbeit notwendig. Wenn bei einer Bewegung Reibung auftritt, wird ein Teil der Arbeit oder der …
