If you can find Walter Lewin's courses online, they can get you through the first years of physics. The main way to learn physics though, on your own or in a program, is by doing problems and labs. You can start by doing the coursework you find for an established class. Another is by working through problems in a text book. As for labs, hacking together what you can is both valuable and rewarding. A few examples are estimating absolute zero, measuring the coefficient of friction, exploring momentum with ball bearings. A few other things that I have found work for me. First, work towards a goal. Whether that be to calculate the orbit of a planet, understand quantum tunneling, or estimate a dynamic process. The second is to take the time follow thoughts as far as you can, using the social communities and resources available on the web (quora, reddit, etc).
