The optical and radio rotation curves of 57 galaxies were analyzed. It is shown that, in passing along the Hubble sequence from early-type to late-type disk galaxies, their dynamical quantities show systematic variations. It is noted that the Hubble sequence can be considered as a sequence of variations of these quantities under the same mass, and the morphological type is a main factor in determining the various quantities. The dispersion in each of these quantities within a given morphological type is related to the mass of the galaxies as well as to other factors. The tidal effect is also found to be an important factor which affects the dynamical state of galaxies.
