Morphology

law + of + physics

The meaning 'a statement describing a fundamental principle in physics' is directly derivable from combining 'law' (a general rule) with 'physics' (the study of matter and energy), with 'of' marking the relationship. This is a straightforward, compositional noun phrase following a common cross-linguistic pattern, so a B1 learner who knows the constituents will readily understand it.

Etymology

The expression law of physics uses law the way we use it for rules among people, but it is applied to physics, the part of nature we study. It gives the image of nature following fixed rules, so the phrase means 'a basic rule that always works' in the physical world.
