How does a nigga learn physics?
Do you just memorize a new one formula, see where it came from then practice 5 problems, and so on?
I legit don't know where to start.
I'm already studying from other 3 subjects with 3 +1000 pages books so I don't have time for Giancoli or Resnick

Pretty much what you just described, but don't call them formulas. That triggers the autists. Call them theorems. Math really does boil down to memorizing facts, and building up a toolbox of your own that you can use to solve problems.

Watch all of 3blue1brown's videos. You want to do more then mindlessly carry out calculations. You want to gain an intuitive understanding of the principles behind the math. His visuals go a long way towards helping you understand an often indescribable message behind the equations.

I know the math; I just don't know literally any physics.
It was the last class in high school and I always skipped it because I had to work in a Manga store.
The teacher knew that I had to work so he gave me a B, he was cool.
I decided to take one year off to see what career I would choose.
Now the year is half gone and I need to learn physics.
Sorry for my bad england

Depends what you mean by “learn physics” I guess. If you’re interested in physics because you really want to know how shit works on a deep level, then focus on the axioms, what they really mean, and how everything builds from them. For example, look at Newton’s laws, really think about what’s definition and what’s actually making a claim about the real physical world, and stew on it. As far as I can tell, Newton’s laws, in the absence of any actual force laws (GMm/r^2, kQq/r^2, etc) are literally just definitions, not claims about the universe. First law defines what “force-free” motion looks like. Second and third laws define how to measure mass and force. Once you get the laws, it’s just math to derive shit, not physics. On the other hand, if you’re just trying to learn shit for a degree, yeah, just focus on the equations. There’re usually only a finite subset of feasible problems to ask about that’re solvable without a computer, so doing a bunch of practice problems is sufficient. Just depends on your goals, yo

There are many fields in physics. Usually you can start with Newtonian physics. Then electronics, optics (diffraction etc, you can potentially read historical authors like Descartes). Basic chemistry is also useful. Then there are more complicated ones like electromagnetism, organic chemistry, thermodynamics, mechanics. Then even further are quantum physics and chemistry , relativity, particle physics...

You don't memorize formulas, that's wrong way.

I don't think that I will be able to derive the entirety of physics in the test bro.

It will take you 6 years of study 6 hours a day with a group of peers to debate with. Its easy to write you a list of 100 books but you'll do nothing.

I recreated schrodinger's equation experimentally during an exam, so yes you can.

It's just the high school level of these themes so I don't think it would take that long.
