The only way to get better in physics is practice with problem solving. Do you have access to physics problems for you to practice with at all?
I have a NAUI master study guide that Ron B. put together and it has some good problems in it but still really hard to grasp by just reading it. I am a hands on learner (visual) not books. I have a lot of common sense but the physics are just stumping me. I am great at math and problem solving when I am shown how to do it. It's just in those equations there have so many numbers and I am unsure where he gets them from.
The Naui MD book is not "CLEAR" in explaining it out. I get the gas laws and understand why they are the way they are I just dont get how to clearly solve X in most of the questions if there not basic.
