Dynamics of relativistic outflows along the rotation axis of a Kerr blackhole is investigated using a simple model that takes into account therelativistic tidal force of the central source as well as the Lorentz force dueto the large-scale electromagnetic field which is assumed to be present in theambient medium. The evolution of the speed of the flow relative to the ambientmedium is studied. In the force-free case, the resulting equation of motionpredicts rapid deceleration of the initial flow and an asymptotic relativespeed with a Lorentz factor of 2^1/2. In the presence of the Lorentz force, thelong-term relative speed of the clump tends to the ambient electrical driftspeed.Comment: 17 pages, 5 figures, expanded version to appear in Int. J. Mod.
