We study the meson potential energy in a non-conformal model at both zero and finite temperature via gauge/gravity duality. This model consists of five-dimensional Einstein gravity coupled to a scalar field with a non-trivial potential. Interestingly, at both zero and finite temperature we find that the relative meson potential energy can be considered as a measure of non-conformality of the
theory. At zero temperature we show that parameters of the Cornell potential, i.e. Coulomb strength parameter �ú and constant C depends on the energy scale ïÿý? that breaks conformal symmetry and the difference between the number of degrees of freedom of UV and IR fixed points ïÿý??N while QCD
string tension ïÿý?s just depends on the ïÿý?. At finite temperature we see that there is a melting length
lm` where beyond that the meson dissociates in the plasma and by increasing ïÿý? the value of lm`increases while its value is independent of the temperature.
