Surface Forms

Newton's law singular

Morphology

Newton's + law

The phrase is compositional: the possessive 'Newton's' indicates authorship/by Newton and 'law' denotes a general scientific rule, so the meaning 'a scientific rule formulated by Newton' is directly derivable from the parts. This possessive + noun naming pattern for scientific laws is common cross-linguistically, making it immediately understandable to a learner who knows the constituent words.

Etymology

Newton's law comes from the scientist Isaac Newton; one popular story says he saw an apple fall and wondered why things move. He wrote simple 'rules' about how pushes and pulls make objects start, stop, or change direction, so Newton's law now means the basic 'rules' that explain how objects move.
