Columb's law friction
WebA modification of Coulomb’s law of friction uses a variable coefficient of friction that depends on a power law in the energy of mechanical oscillation. Through the use of three different exponents--0, ½, and 1; all commonly encountered non-viscous forms of damping are accommodated. The nonlinear model appears to yield good agreement with ...

In contrast ...
WebDefinition. Dating back to 1699, Amontons’ laws of friction assert that there exists a proportionality between friction force and the applied load, and that the friction force is independent of apparent contact area. While well-known in the field of tribology, these so-called “laws” are predated by the work of Leonardo da Vinci and are ...
