Unsolicited advice: The role of “voice” in science is no less important than in literature or film or art. When you place yourself in the hands of a single person who is an expert in a topic, you give yourself a fighting chance to learn to see the world the way they do. Over time, as you become accustomed to a “voice” it will become easier and easier to grasp the material. You will become accustomed to their way of writing equations, deriving ideas, setting you problems.
For this reason, for any given topic, it is best to use one book as your primary guide through a topic rather than jumping around from book to book. When you encounter a problem with the text, in which you suspect that something is not being explained as well as it could be, you can divert to other texts, and once satisfied, go back to your original book. If, when done with an entire book, you feel you want to go through the subject a second time, start with a second book and proceed in the same way.
In choosing which book to use, use your intuition. A few pages will give you a sense of their voice. Feel free to choose a voice you like. The material is largely the same across books. Once you have followed one author for a period, be quite wary of switching horses in midstream.
1. General Physics
2. Classical Mechanics
All of these are excellent. Personally I find Taylor the easiest. Note that Cohen and Feynman are *free*, whereas the Taylor and Lange and Morin PDFs are only to be used by students who have purchased copies themselves (as the author of this webiste has). The PDFs allow study when the book is not near at hand.
