Morphology
coefficient + of + friction
The phrase is compositionally built from 'coefficient' (a numeric factor) and 'friction' (resistance between surfaces), so its meaning as a numerical measure/ratio describing friction is directly derivable from the constituents. The grammatical 'of' simply links the modifier to the head, and equivalent constructions exist in many languages, making this term readily understandable to learners who know the component words.
Etymology
Coefficient of friction names a single number that tells how much two surfaces friction, or 'rubbing', against each other, with coefficient meaning 'a number' and friction meaning 'rubbing'. So imagine a small number sitting between a shoe and the floor that says 'how hard it is to slide' — that is why the phrase means how hard one object is to move over another.
