  In this paper, we examine the thermodynamics of heavy quarkonium in the
spinning black hole background. Specifically, we investigate the effect of
angular momentum on the interquark distance, free energy, binding energy,
entropy, entropic force, and internal energy of heavy quarkonium from the
thermodynamic relationship. Our findings indicate that the angular momentum
reduces the maximum value of interquark distance, suggesting that it promotes
the dissociation of quarkonium. Additionally, we observe that the angular
momentum suppresses free energy. From the results of binding energy, the
angular momentum favors the melting of meson into a free quark and antiquark.
Moreover, the results show that angular momentum increases the entropy and
entropic force, thus accelerates the dissociation of quarkonium. The angular
momentum increases the internal energy at large interquark distance. Finally,
we find that the angular momentum has a more pronounced effect on quarkonium
when the axis of quark pair $Q\overline{Q}$ is transverse to the direction of
angular momentum.
