Abstract
We show that. even in the most favorable case, the motion of a small spheri cal tracts suspended in a fluid of the same density may differ from the cor responding motion of an ideal passive particle. We demonstrate furthermore how its dynamics may be applied to target trajectories in Hamiltonian syste ms.
