Usage Note
Propulsion is used in engineering, physics, and everyday language to describe the force that drives something forward — propulsion à réaction (jet propulsion), propulsion nucléaire (nuclear propulsion). The verb propulser means 'to propel', and propulseur (m) refers to a thruster or propellant. The word also appears figuratively, as in propulsion vers le succès — 'propulsion toward success'.
