![]() G-forces, short for gravitational forces, act on us a lot more than you’d probably think. But how exactly can acceleration harm us, and how fast can we go before our need-for-speed mentalities get us killed? Things Just Got Heavy Though they’re capable of providing fun, G-forces are also a formidable foe to the human body, capable of taking us out within a few seconds if we underestimate them. ![]() G-forces are a measurement of the type of acceleration that causes weight, like the kind you feel when you’re pressed into your seat during a roller coaster loop. But coaster designers can’t simply throw human bodies into high speeds with abandon - they must also carefully calculate the G-forces at work in order to make sure the coaster is safe. G-LOC is the Gravity-Induced Loss of Consciousness.If you’re a roller coaster enthusiast, chances are you’ve been called a “thrill-seeker” or an “adrenaline-junkie.” But what is it about roller coasters that gives the rider a high-impact, thrilling experience? Many cite the high speeds and inversions as the reason they ride the massive metal machines, but in reality, it’s probably the acceleration into these components of the ride that truly creates the experience. Must read: How Safe Is A Roller Coaster In The Sky? G-LOC Captured On Video You’ve just experienced the onset of Gravity Induced Loss of Consciousness (GLOC). You will begin to get tunnel vision, then things will lose color and turn white, and finally everything will go black. Your 10-pound head will weigh 90 pounds when you pull 9 G’s! If you continue to pull high G’s, the G-force will push the blood in your body towards your feet and resist your heart’s attempts to pump it back up to your brain. ![]() Professional pilots like the Blue Angels typically hit 6 G’s - but under special circumstances (and in training), they can approach up to 10 G’s.Īs you pull more G’s, your weight increases correspondingly.Airline passengers aboard a commercial airline reach about 1.5 G’s.See how fighter pilots learn to survive inhuman levels of G-force. Fighter pilots can pull 9 G’s vertically.Astronauts aboard a space shuttle reach about 3 G’s.The highest G-force on a roller coaster ever was 12 G’s. The Slingshot ride G-force is between 3 to 5 G’s and can cause you to pass out several times during the ride. See how many G’s riders in Disney’s Orlando parks experience. Roller coaster riders pull various levels of G’s - but they rarely get much beyond 4 G’s, according to Sanjay Gupta.G and the G Forces How Gravitational Forces Affect Your Body It’s hard for the human body to take, although my pilot seemed to be enjoying it and joking the whole time, sometimes at my expense. Higher G’s and your lungs start to collapse, your esophagus stretches, your stomach drops and blood pools significantly in your legs. In our daily activities, we rarely experience anything other than 1 G.įrom a medical standpoint, at 4 G’s, you will start to lose color vision, which is why it is called “graying out” - 4.5 G’s and you may lose vision all together. The force of gravity when you sit, stand or lie down is considered 1 G. #2 – Use this as a baseline for understanding G-force: That means: If you weigh 100 lbs, you would weigh 400 lbs. I bet you’re asking, “ What is G-force, anyway?” These 2 points have helped me understand what Gravitational force means: #1 – Here’s how G-force relates to your body weight:Ĥ G’s means 4 times the force of gravity - which alone is a force to be dealt with. Here’s what I’ve recently learned about Gravitational force… What Exactly Is Gravitational Force? Gravitational force has always been interesting to me - ever since Jim told me that our favorite NHRA driver, Terry McMillen reaches between 3 and 3.5 G’s behind the wheel of his Top Fuel drag racing car each time he goes down the track.īut I’ve never really understood how G-forces work and how many G’s do what to your body - until now. I saw an interesting report on CNN the other day.
