Helicopter (on the ground), it's pilot, a mechanic and one crazy man with an AK-47. Top speed: 0 mph. Maximum Altitude: Depends on throwing strength of the user.

Barely over a quarter of normal Earth gravity. To equal 1g of acceleration, a car would need to get to 60 in 2.74 seconds, roughly. If we want to be really, really exact, it looks like 1g is getting to. G-Force sensor accelerometer 1.0.0 Apk for Android (com.playworkout.gforce), Created by Dmitriy Simanenkov in Tools Apps.

Share Inquiry: AN OCCASIONAL COLUMN All About G Forces What's behind gravity forces, and how much of them can we take? • By Peter Tyson • Posted 11.01.07 • NOVA A few summers ago I took my then nine-year-old daughter on a glider ride.

Midway through, as we soared over a coastal landscape, I casually asked the pilot whether he could do any tricks. Without a word, he threw the plane into a dive. We were accelerating straight towards the ground. My daughter and I shouted and grabbed the armrests. Suddenly we were hit with that thrill-inducing pressure familiar from rollercoasters—tensed facial muscles, light-headedness, a sense of altered reality. The pilot pulled up, and all we could see through wide-open eyes was sky.

We zoomed straight up until the glider ran out of pizzazz, then the pilot tipped it over into another sheer drop. Again, squeezed faces, dizziness, otherworldliness.

After two or three loop-the-loops, the thrill became dread: Would he ever stop? My daughter was laughing, but I thought I would pass out. What was going on? What happens to us physiologically when we start 'pulling G's,' as pilots label what we were feeling? Why was the sensation most pronounced as we swooped out of a dive? Might the glider pilot, I wondered at the time, pass out himself? 'Fainting in the air' Before the advent of airplanes, which could accelerate the human body like nothing before, people rarely experienced G forces.

So-called gravity forces first became a concern during World War I, when pilots began mysteriously losing consciousness during dogfights. As early as 1919, a doctor wrote up this strange phenomenon for the literature, calling it 'fainting in the air.'

With the development of faster and more maneuverable planes, G forces became more dangerous. Based on rates of survival (or lack thereof) during crashes, it became accepted wisdom that no pilot could withstand more than 18 G's, or 18 times the force of gravity at sea level.

So cockpits were designed to withstand only 18 G's. Yet pilots sometimes walked away from crashes in which the G forces were calculated to have been much higher. In the mid-1940s, an Air Force physician named John Stapp began to suspect that it was the mangling effects of a crash and not the G's that killed pilots. Hoping to improve cockpit safety, Stapp set out to determine just what humans could take in the way of G forces. He built a rocket-powered sled, the 'Gee Whiz,' which accelerated a tightly strapped-in body—initially a dummy but soon Stapp himself—to extraordinarily high speeds along a track before coming to an almost unimaginably abrupt stop.

By the late summer of 1948, Stapp had done 16 runs himself and withstood up to 35 G's. He lost dental fillings, cracked a few ribs, and twice broke a wrist, but he survived. Still he was not satisfied. Eager to know what pilots ejecting at high speed could endure in terms of sudden deceleration, Stapp built a new sled called 'Sonic Wind' in the early 1950s. On what became his final run, in December 1954, Stapp decided to pull out all the stops. Firing nine solid-fuel rockets, his sled accelerated to 632 miles per hour in five seconds, slamming him into two tons of wind pressure, then came to a stop in just over one second.

A witness said it was 'absolutely inconceivable anybody could go that fast, then just stop, and survive.' But Stapp did—in fact, he went on to live another 45 years, dying quietly at home in 1999 at the age of 89—and he experienced a record-breaking 46.2 G's. For an instant, his 168-pound body had weighed over 7,700 pounds. Stapp's efforts put him on the cover of Time, and he was called 'The Fastest Man on Earth.' More importantly, his work led to greatly improved safety in both planes and cars, and he gave us a much-improved understanding of human tolerance to G forces. A matter of acceleration Even before Stapp it was well-known that G forces have less to do with speed than with acceleration—the change in speed over time.
