What can I use to teach myself physics?

[guitarphysics]

I'm 15 years old and want to go faster than my high school class. I'm teaching myself calculus from a couple of different books as well as videos from khanacademy. I'm also going to use the Feynman lectures on physics, but apparently those are better as secondary sources. What do you recommend I use as a primary textbook?
Thanks

If you know basic calculus (simple derivatives and integrals), you can probably handle a calculus-based university intro physics textbook. Examples:

There are others. They all cover pretty much the same material. You can save money by buying a used copy of an older edition. Changes between editions are usually pretty small, just enough to force students taking a course to buy the latest edition so everyone is "on the same page."
