The paper shows the results of studies on the influence of an external normal harmonic force upon reduction of a friction force, in the system of two bodies in a planar contact. It has been pointed out that, the main reason for the friction force reduction is due to dynamical effect; kind of stick – slip monition. Nature of the phenomenon has been described and explained in the article. The computational studies have been validated with experimental results available in literature. Moreover a nondimensional relation, between forces acting on a slider and average velocity of the slider, has been found.
