If you want to learn physics, start with math. Go at least through differential equations and linear algebra.
Then get a good engineering physics textbook and read it. After that, you can start on quantum mechanics and special relativity. Don't expect to do general relativity until you have had more math (at least multivariate calculus and some more advanced linear algebra involving tensors).
