The word "impact" originates from Latin impactus (past participle of impingere), combining im- (a variant of in-, meaning "into" or "against") and pact- (from pangere, meaning "to fasten" or "to drive in"). The original sense referred to physical collision, but over time, it expanded metaphorically to denote strong influence or effect, reflecting the "forceful contact" logic.
