In many fields of the multi‐body world friction must be taken into account. Friction is usually reduced to a ratio: the coefficient of friction. Newer theories also consider dynamic friction laws. For the use in multi‐body models, a stepped complexity and measurably hedged description of the friction is necessary. Therefore, different experimental designs that allow dynamic measurements are discussed. An example friction pair is investigated by measurements and the quality of the results is pointed out.
