Scientific paper
The motion of a single particle in the bending wave of finite thickness in a planetary ring is studied. The forcing due to the planet, the moon, the Coriolis force, and the self gravity of the ring are included. In particular, the variation of the velocity arising due to the variation of the amplitude and the phase of the epicyclic motion across the height of the ring is studied. It is suggested that the dissipation of energy of this shear layer through collisions of ring particles from different heights may contribute significantly to the damping of the bending waves observed in the Voyager data.
