The evolution due to dynamical friction in a rotating isothermal system is studied, and while the changes in the density profile were found to be marginal, the rotational velocity was seen to increase, with rotation curves flattening with time. It is suggested that if dynamic friction is significant in clusters of galaxies, brighter galaxies should have different rotational properties from the less massive ones. The M/L ratio was shown to remain constant as long as the value of central mass remains within the limits that are observed for clusters. It is also found that when the heavy objects subsystem and the main system are not corotating, no significant spinning up or slowing down of the heavy objects subsystem occurs. M(r = 0) is shown to depend on lambda, indicating that if galactic nuclei form from the decay of globular clusters, elliptical galaxies should have more massive nuclei than spiral ones.
