WebJan 1, 2004 · G-induced loss of consciousness (G-LOC) occurred in 9% of the trainees, most commonly on the GOR, less often on the 9-G RORs. Motion sickness was a significant problem in less than 1% of the... The term g-"force" is technically incorrect as it is a measure of acceleration, not force. While acceleration is a vector quantity, g-force accelerations ("g-forces" for short) are often expressed as a scalar, with positive g-forces pointing downward (indicating upward acceleration), and negative g-forces pointing upward. Thus, a g-force is a vector of acceleration. It is an acceleration that must be produced by a mechanical force, and cannot be produced by simple gravitation. Objects acte…
