in- (in, onto, assimilated to im-) + petere (to rush) gives impetus, 'a forward-driving force'; + -ous = 'full of that headlong force.' An impetuous person acts with the same unchecked rush — leaping before looking.

Why It Means This

impetuous is the human face of impetus: the physics word for momentum became a personality trait. The link is the image of unstoppable forward motion — once it starts, it can't easily be checked. Note: it's not a compliment. It frames quick action as rash, driven by feeling rather than judgment.
