hello math and science nerd friends

I have a sudden burning desire to learn basic physics. are there any great online tools for this, particularly for someone who actually learns really well via textbooks and quizzes, but doesn't have much ability to "book" free time in advance?

also, what level of math would I need to brush up on, and where might you suggest I do that?

I'm up for unusual suggestions, but I don't have a lot of money and the #1 thing I don't want (the reason I abandoned the library-book approach) is some high-level philosophical bullshit about space. I do not care about the origins of life right now, I care about being able to comprehend energy and mass and various forces so I can then later find out why that was three levels of oversimplification. :blobcatmaths:
