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.
