Vis viva

Vis viva (from the Latin for "living force") is an obsolete scientific theory that served as an elementary and limited early formulation of the principle of conservation of energy. It was the first (known) description of what we now call kinetic energy or of energy related to sensible motions. Proposed by Gottfried Leibniz over the period 1676–1689, the theory was controversial as it seemed to oppose the theory of conservation of momentum advocated by Sir Isaac Newton and René Descartes. The two theories are now understood to be complementary.
