- Friction - Wikipedia
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding or grinding against each other [2][3] Types of friction include dry, fluid, lubricated, skin, and internal – an incomplete list The study of the processes involved is called tribology, and has a history of more than 2,000 years

- 5. 1 Friction - College Physics 2e | OpenStax
Friction is a force that opposes relative motion between surfaces in contact One of the simpler characteristics of friction is that it is parallel to the contact surface between surfaces and always in a direction that opposes motion or attempted motion of the systems relative to each other
