Does surface area affect friction coefficient
WebMar 27, 2024 · As can be seen, the friction coefficient is mostly affected by the following factors: mutual distance between micro-recess edges, surface free energy, recess diameter and rate of blackening. The correlation coefficient has a higher value for tests conducted at the speed of 600 rpm, thereby pointing to a stabilizing effect of the dynamic ...

WebJan 15, 2024 · In this lab, students will measure coefficients of friction and show that the frictional force doesn’t depend on surface area in contact. Friction is independent of the area of contact. The reason behind this is that the actual area of contact on an atomic scale is a fraction of the total surface area. WebMar 26, 2016 · The force due to friction is generally independent of the contact area between the two surfaces. This means that even if you have two heavy objects of the same mass, where one is half as long and twice as high as the other one, they still experience …
