Abstract: A scalar potential model (SPM) was developed from considerations of galaxy clusters and of redshift. The SPM is
applied to H I rotation curves (RCs) and RC asymmetry of spiral galaxies. The resulting model adds the force of a scalar
potential of the host galaxy and of neighboring galaxies to the Newtonian rotation velocity equation. The RC is
partitioned radially into regions. The form of the equation for each parameter of each region is the same with differing
proportionality constants. Integer values of each equation are determined empirically for each galaxy. Among the sample
galaxies, the global properties of galaxies of B band luminosity, of position, and of orientation determine the RC and RC
asymmetry. The Source of the scalar field acts as a monopole at distances of a few kpc from the center of spiral galaxies.
The scalar potential field causes Newtonian mechanics to considerably underestimate the mass in galaxies, which is the
“missing mass problem”. The SPM is consistent with RC and RC asymmetry observations of the sample spiral galaxies.
