We present results on the spin-independent quark-antiquark potential in SU(3)
gauge theory from a simulation on a 48^3*64 lattice at Beta = 6.8,
corresponding to a volume of (1.7 fm)^3. Moreover, a comprehensive analysis of
spin- and velocity-dependent potentials is carried out for SU(2) gauge theory,
with emphasis on the short range structure, on lattices with resolutions
ranging from .02 fm to .04 fm.Comment: 10 pages, uucompressed latex with 5 ps figures, epsf style require
