I can't afford the number of books that would be needed.

Thanks, I'll have to look at it in detail later.

I am a high school teacher in San Diego, CA, USA. I enjoy physics very much and would like to be a part of this forum.

First post here, so apologies if there is a similar thread. None came up on my first search. I am looking for a free online calculus based physics textbook suitable for introductory physics. Thanks in advance.
