  Previously, two of the present authors obtained the decoupling limit and the
corresponding throat geometry of non-supersymmetric D3 brane solution of type
IIB string theory. In analogy with the supersymmetric case, it describes the
gravity dual of a non-supersymmetric gauge theory with QCD-like properties such
as running coupling and confinement (or mass gap) in certain range of its
parameters. In this paper, we consider a `black' version of the
non-supersymmetric D3 brane solution in the decoupling limit and use this
gravity background to holographically compute the expectation value of a
time-like Wilson loop which, in turn, is related to the potential of a heavy
quark-antiquark pair. By boosting the gravity solution along one of the brane
directions and placing the pair at an arbitrary orientation with this
direction, we numerically obtain the variation of the screening length as well
as the potential with velocity, its orientation with respect to the direction
of motion and other parameters of the theory. Remarkably enough, our results
are in qualitative agreement with those obtained holographically in
supersymmetric gauge theories indicating that these features are quite robust
and universal as they are insensitive to the presence of any supersymmetry in
the theory. The physical interpretations of the variations with respect to the
other parameters of the theory, not observed in supersymmetric theory, have
also been given.
