"Fundamental Laws of Mechanics" (along with "Basic Laws of Electromagnetism") is perhaps the best text book on introductory physics. Each topic is expounded with great lucidity and preciseness, and goes straight to the heart of the matter. It is useful to have a good basic understanding of multivariable calculus before studying from this book. This book also supplements the corresponding chapters of "Problems in General Physics" (by the same author) very well.
