Popis:	This paper derives an equation of motion which shows in a direct way how the motion of a point within the body is related to geodesic motion as the body tends to a test particle. This equation is used firstly to show that under reasonable conditions the geodesic law in the limiting sense of a test particle is exactly true for an ideal fluid. Secondly, it is used to construct an example showing how the geodesic law may be violated if is not related to particle velocity in an appropriate way.
