这样我就更搞不清楚这是一个什么单位了
Question - How do I measure g forces? Also, how would I subject a
person to any number of g's for a period of time? Also, what are the
effects of g forces on the body?0 w# ?+ u7 u$ x& t0 t

The measurement of g-forces is done with an accelerometer. The term
'g-force' is really a misnomer. It is actually the acceleration a mass1 ]1 P' ^* z5 m5 r- W7 }3 q3 D' A" S; D
experiences in a given situation. On earth, one g is about 9.8 m/s^2. Let7 Z$ R, M# L! \8 K. f
us call it 10 m/s^2 as an approximation. If you are at 2 g's, you are at
about 20 m/s^2 acceleration. Most people begin to feel very lightheaded
and may even grey out at about 4 g's. That is why amusement rides try to; r4 M, G2 k% B4 _ L9 c$ V
stay under this acceleration.
查到这么一段话,现在猜到g's的意思了:
g--表示重力加速度
s--英语语法里面的复数表示形式" }; j0 s, O2 {&quo
