This is a specialized technical term used primarily in physics and engineering education and research. Named after French physicist Jean le Rond d'Alembert (1717-1783), it is used universally in both Brazilian and European Portuguese scientific contexts without regional variation. The concept is fundamental to mechanics courses at the university level.
