Existing or following as a result or consequence; especially, resulting from the combination of two or more agents: as, a resultant motion produced by two forces. See diagram under force, 8.n. That which results or follows as a consequence or outcome.n. Synonyms Result, Resultant. A result may proceed from one cause or from the combination of any number of causes. There has been of late a rapid increase in the use of resultant in a sense secondary to its physical one—namely, to represent that which is the result of a complex of moral forces, and would be precisely the result of no one of them acting alone.
