In what situations do fighter pilots experience instantaneous upto 9g acceleration up their spine as an almost direct transfer of energy from a physical strike to the Hull of the vehicle they are piloting?
an acceleration of 9g defines the force being developed on the mass being accelerated
ie 9g is the quantification of the 'direct'ness of transfer of energy
how does (so-called) instantaneous mean anything ?
whenever a 1kg grapefruit is accelerated at 9g it will experience a force of c.100N
100N instantaneously or going through 10N, 20N, 30N .... 80N, 90N, finally 100N ? - it makes no difference to the fruit
people may be inferring from 'instantaneous' that the force is 'high'
not so - the force is already defined by the g value
