In certain circumstances, one may measure surface tensions that are different from
the equilibrium value. Such a surface tension is called the dynamic surface (or interfacial)
tension
(
or
). The equilibrium value is then called the static surface (or interfacial) tension
(
or
). The modifying signs may be omitted if there is no danger of ambiguity.
