You already have plenty of incentive to learn the origin of impetus, so we won't force the point. Impetus comes from Latin, where it means "attack or assault"; the verb impetere was formed by combining the prefix in- with petere, meaning "to go to or seek." Petere also gives us other words suggesting a forceful urging or momentum, such as appetite, perpetual, and centripetal. Impetus describes the kind of force that encourages an action ("the impetus behind the project") or the momentum of an action already begun ("the meetings only gave impetus to the rumors of a merger").
