The g-force or gravitational force equivalent is a mass-specific force (force per unit mass), expressed in units of standard gravity (symbol g or g 0, not to be confused with "g", the symbol for grams).
The scale model is typically constructed in the laboratory and then loaded onto the end of the centrifuge, which is typically between 0.2 and 10 metres (0.7 and 32.8 ft) in radius. The purpose of spinning the models on the centrifuge is to increase the g-forces on the model so that stresses in the model are equal to stresses in the prototype.
1:29 G scale boxcar by Aristo-Craft on G gauge track 1:32 scale 2-bay offset hopper by Mainline America. G scale or G gauge, also called large scale (45 mm or 1 + 3 ⁄ 4 inches), is a track gauge for model railways which is often used for outdoor garden railways because of its size and durability.
Some Japanese toy manufacturers also produce aircraft toys in this scale. Rare model rail scale from Germany. 1:56: 5.442 mm Another common scale for 28 mm figure scale wargaming vehicles - manufacturers in this scale include Wargames Factory, Die Waffenkammer/JTFM Enterprises, NZWM/Army Group North, Force of Arms and Warlord Games. 1:55: 5.644 mm
Large-scale gravity anomalies can be detected from space, as a by-product of satellite gravity missions, e.g., GOCE. These satellite missions aim at the recovery of a detailed gravity field model of the Earth, typically presented in the form of a spherical-harmonic expansion of the Earth's gravitational potential, but alternative presentations ...
Peak ground acceleration can be expressed in fractions of g (the standard acceleration due to Earth's gravity, equivalent to g-force) as either a decimal or percentage; in m/s 2 (1 g = 9.81 m/s 2); [7] or in multiples of Gal, where 1 Gal is equal to 0.01 m/s 2 (1 g = 981 Gal).
The standard acceleration of gravity or standard acceleration of free fall, often called simply standard gravity and denoted by ɡ 0 or ɡ n, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth.
The dependence of a coupling g(μ) on the energy-scale is known as "running of the coupling". The theory of the running of couplings is given by the renormalization group , though it should be kept in mind that the renormalization group is a more general concept describing any sort of scale variation in a physical system (see the full article ...
