G-Man (slang) the Movie of the same name. G-Man (slang) G-Man (short for "Government Man") is an American slang term for special agents of the United States Government. It is specifically used as a term for a Federal Bureau of Investigation (FBI) agent. "G-Man" is also a term used for members of G Division, essentially a British anti-rebel police unit operating out of Dublin Castle prior to Irish Independence in 1922. Colonel Ned Broy uses the term in his official testimony for the Irish Army's Bureau of Military History in their archive of the Easter Rising (1916) and the Irish War of
G-force Tomas Scheckter's car. This immediately resulted in Bräck's car impacting the catch fence that would record a peak of 214 G-force. Impact and mechanical shock are usually used to describe a high kinetic energy, short term excitation. A shock pulse is often measured by its peak acceleration in g-s and the pulse duration. Vibration is a periodic oscillation which can also be measured in g-s as well as frequency. The dynamics of these phenomena are what distinguish them from the g-forces caused by a relatively longer term accelerations. After a free fall from a height formula_1 the shock on an
