Newtonian mechanics is taught as part of every physics program for several reasons. It is a towering intellectual achievement; it has diverse applications; and it provides a context for teaching modelling and problem solving. This text gives equal prominence to all three missions. It therefore includes some advanced material as well as the customary introductory topic and is designed to be studied over an extended time-frame, somewhat beyond the first year of an English university physics programme. The problem-solving aspects are developed more fully than in many other texts; showing students how problems are approached and bringing out the ways of going about constructing a model and solution. Each chapter starts with a problem, for which the following text provides the background to a solution. I hope that knowing what the question is makes the following material more digestible.
