Зато коэфицент трения может зависить от давления/площади, внезапно. Привет автомобильные покрышки, например.

Внезапно, нет. Коэффициент не зависит. Он зависит от природы вещества и "качества" поверхности.

It's important to note that the coefficient of friction is not dependent on the area of contact. This might seem counterintuitive, but even if you increase the contact area, the weight distribution also increases, cancelling out any potential increase in friction.

Another factor that can influence the coefficient of friction is the presence of a lubricant. Lubricants, such as oil or grease, can significantly reduce the coefficient of friction by creating a thin layer between the two surfaces, reducing their direct contact and thus, the friction.

Additionally, the pressure applied to the surfaces in contact can alter the characteristics of the frictional force, although it doesn't directly change the coefficient of friction.
