These forces are capable of getting much more intense fighter pilots and astronauts, for example, often subject themselves to rapid accelerations to high speeds. Any time you speed up or slow down, they’re there (think being thrown forward against your seatbelt in a rapidly halting car, or when you experience intermittent moments of weightlessness on a theme park ride or on a flight). 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. 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.
