  Social free energy has been recently introduced as a measure of social action
obtainable in a given social system, without changes in its structure. The
authors of this paper argue that social free energy surpasses the gap between
the verbally formulated value sets of social systems and the quantitatively
based predictions. This point is further developed by analyzing the relation
between the social and the physical free energy. Generically, this is done for
a particular type of social dynamics. The extracted type of social dynamics is
one of many realistic types of the differing proportion of social and economic
elements. Numerically, this has been done for a toy model of interacting
agents. The values of the social and physical free energies are, within the
numerical accuracy, equivalent in the class of non-trivial, quasi-stationary
model states.
