Coefficient of friction vs Drag factor

Drag factor and coefficient are expression commonly used in crash investigation and reconstruction. They are usually used to calculate vehicle speed calculations based upon tyre mark geometry. The coefficient-of-friction μ is defined as the ratio of the tangential force F(tan) (parallel to the surface) applied to an object sliding across a surface to the normal… Read More
