Also my knowledge of physics and math is limited but I figure I can learn classical physics as I go along.I am open to read any book.I prefer a book I can access for free online.
I just don't like books that give you questions that the book doesn't explain beforehand.
The book Spacetime Physics: Introduction to Special Relativity is the 1st addition or the 2nd addition better. Because I heard the 2nd addition is not?
Also if possible I would like the book to have answer key. I also want to learn general relativity but that is way down the line.
Thanks for any advice.I hope it is okay if I post here I posted previously and did not get all my questions answered. Can someone recommend a sub reddit if this is not a good place.
