Newtonian mechanics
From Glossary of Meteorology
(Also called classical mechanics.) A system of mechanics based on Newton's laws of motion.
The salient characteristics of Newtonian mechanics are that mass and energy are separately conserved, all physical variables can take on a continuous set of values, the state of a system at any instant uniquely determines its state at any later instant (determinism), and interactions at a distance are instantaneous.
Compare quantum theory.
