G-Man (Half-Life) refers to simply as his "employers". His mysterious nature has made him an icon of the "Half-Life" series, with his identity and motives remaining almost completely unexplained. The G-Man's name comes from "G-Man", an American colloquialism meaning "Government Man". However, within the "Half-Life" games, he is identified by this name only in the program code and the multiplayer profile menu as a default name option, not within the story itself; his name is derived from his "Half-Life" model and entity name and has since been reused in subsequent games of the series. His name has been confirmed and he has
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
