🎤Pronunciation
🌳Etymology
Origin
Law derives from Old English 'lagu', originally meaning a fixed principle or rule. Motion comes from Latin 'motus', the past participle of 'movere' (to move), meaning movement or change of position. The compound term 'law of motion' emerged as a scientific phrase during the systematization of physics, particularly through Newton's formulation of fundamental mechanical principles in the 17th century.
Breakdown
Law (Old English 'lagu': a fixed rule or principle) + of (preposition indicating relationship) + motion (Latin 'motus': movement, from 'movere' meaning to move). Together, the phrase denotes a fundamental principle governing the behavior of physical bodies in movement.
