): Much easier to tolerate. This is what you feel when a car accelerates. Because the blood stays on the same horizontal plane as your heart and brain, we can withstand much higher levels this way. Lateral Gs ( Gycap G sub y
Engineers use G-force data to build better car seats and helmets, ensuring they can withstand the "snap" of a sudden impact. The Bottom Line G-Force
Humans have survived over 200 Gs in extremely brief car crashes, though with severe injuries. ): Much easier to tolerate
Despite the name, G-Force isn't a "force" in the traditional sense like gravity. Instead, it is a measurement of relative to freefall. One "G" is equal to the force of gravity at the Earth's surface. When you feel "2Gs," you feel twice your normal weight. The Different Flavors of Gs Lateral Gs ( Gycap G sub y Engineers
Most modern coasters top out at around 4 Gs .
Most untrained people will pass out at around 4–5 Gs . However, elite fighter pilots using specialized "G-suits" and breathing techniques can sustain 9 Gs while performing combat maneuvers. G-Force in Everyday Life
