Impulse; incentive; vigor; force. 3. The aititude through which a heavy body must fall to acquire a velocity equal to that with which a ball is discharged from a piece. Origin: L, fr. Impetere to rush upon, attack; pref. Im- in + petere to fall upon, seek. See Petition. Source: Websters Dictionary (01 Mar 1998)
