Everything is "just physics"

  That's true, I guess I was imagining more of a Newtonian approach, modern physics has everything.

    Newtonian model gets you a rocket in a vacuum without atmosphere or vibrations made of indestructivle materials. In the real world there is the atmosphere, fluid dynamics of the fuel, combustion stability, material science as engines have to withstand hot and chemically aggressive exhaust, etc.
