Classical mechanics is sketched in elementary terms, from a sophisticated point of view. It is stressed that no formulation of the laws of motion constitutes a complete theory, susceptible of being compared with experiment. Instead, what these laws do is to show how to formulate theories of particular motions, by the introduction of (additional) laws of force. Because the basic force laws are simple in a suitable coordinate system, the over-all theory is simple, and useful, and is believed. The presentation given is designed for pedagogic use.
