In [[physics]], Leibniz proposed the use of "dynamics" or [[kinetic energy]] to explain motion, rather than "mechanics" that is based on [[Cartesian coordinates]]. Leibniz held the view that [[light]] always travelled the path of least resistance. | In [[physics]], Leibniz proposed the use of "dynamics" or [[kinetic energy]] to explain motion, rather than "mechanics" that is based on [[Cartesian coordinates]].
