The g-force acting on an object under acceleration may be downwards, for example when cresting a sharp hill on a roller coaster. If there are no other external forces than gravity, the g-force in a rocket is the thrust per unit mass.
Pink force is the apparent weight on board. The load factor, and in particular its sign, depends not only on the forces acting on the aircraft, but also on the orientation of its vertical axis. During straight and level flight, the load factor is +1 if the aircraft is flown "the right way up", [ 2 ] : 90 whereas it becomes −1 if the aircraft ...
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).

Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity). The unit g (or g) represents multiples of the standard acceleration of gravity and is conventionally used.
Take-off can occur when the vehicle's g-force exceeds local gravity (expressed as a multiple of g 0). The thrust-to-weight ratio of rockets typically greatly exceeds that of airbreathing jet engines because the comparatively far greater density of rocket fuel eliminates the need for much engineering materials to pressurize it.
A Formula Student car performing a skidpad test. (2009) A skidpad or skidpan [1] is a circular area of flat pavement used for various tests of a car's handling. The most common skidpad use is testing lateral acceleration, measured in meters per second squared (m/s 2) or the scaled unit g-force.
