Be careful with "impact."
The clipping below comes from my computer’s built-in dictionary (not my favorite glossary, but convenient.)
“As a verb, impact remains rather vague and rarely carries the noun’s original sense of forceful collision. Careful writers are advised to use more exact verbs that will leave their readers in no doubt about the intended meaning. In addition, since the use of impact is associated with business and commercial writing, it has a peripheral status of ‘jargon,’ which makes it doubly disliked.”
