单词	G-force
释义	G-force /ˈdʒiːfɔːs / noun [mass noun] Physics 1A form of acceleration that causes the accelerating object to experience a force acting in the opposite direction to the acceleration: the Harrier banked sharply left and I experienced my first taste of G-force [count noun]: they were spun around in centrifuges, to acclimatize them to G-forces... The G-force the body must withstand on re-entry into Earth's atmosphere - two to three times the gravitational force we experience on the surface - would likely cause bones to crumble. There's also a built-in G-Force monitor so you can monitor the plane's G-Force while flying and actually see it stay well within a plane's safe limits. "The extreme g-force provided by the centrifuge training provides a close approximation of the rigours of travelling beyond the earth's atmosphere," Mr Dunn said. 1.1The pressure experienced as a result of G-force: the G-force presses me back into my seat... I probably went from 0-50 in 2 seconds, maybe less, but you could feel the G forces push you back into your seat. Trying to control the descent is most dangerous, although the urge to let the engine roar and enjoy the G-force pressing gently down on the gut is strong. The air rushes past as G-force thrusts me back into my seat, my fists clenched on the rails and feet planted at either corner of the passenger compartment. Origin 1930s: abbreviation of gravitational force.
