Understand how roller coasters can make you sick

Have you ever wondered how roller coasters can make you sick? Whether with a little sickness, fear, a sense of having all organs collapse or even uncontrollable cravings: toys are responsible for awakening your senses, but do you know how it happens?

The Washington Post team has created an animation that shows in detail the gimmicks used by engineers who specialize in roller coasters to make anyone at least uncomfortable. Here we show you step by step all kinds of movements made in toys so that you get out of them completely stunned.

1 - The fast jump

Most of the modern roller coasters start the game with a very fast start, starting from 0 to 193 km / h in less than four seconds - instead of the slow, agonizing old climb. The G-Force pushes you all into place while making your cheeks move toward your ears.

2 - You seem to weigh a thousand pounds!

At the end of the climb, the cart begins to descend and you feel as if your weight has quadrupled. The feeling is the same as being flattened, like a cartoon character. Some people even get the impression that the entire bloodstream has started to flow to the feet - that's the positive G-force.

In everyday life, we live with a force of 1G (or once the force of gravity), so any number above that can be impressive. Some roller coasters get you 4 or 5G, but only for a little while, as the sustained force can usually reach 2 or 3G - something like the experience when launching a space shuttle, for example. All of this is what makes it much harder for your heart to pump blood to the brain.

3 - Upside down!

Most toys have loopings, which are the stretches where the stroller goes full circle up and down, leaving you upside down. There are very few cases where you have the feeling that you are going to fall, and that is responsible for inertia; Meanwhile, centripetal force keeps you from flying through the air.

Almost all loops require enormous acceleration to get you through the circle formed by the rails unharmed. Larry Giles, vice president of design and engineering at Busch Gardens, ensures that the forces are so evenly balanced that you wouldn't fall at this stage even if you weren't wearing the belt - although he also says he'll never try it.

4 - Stomach in the throat

As you climb a hill up the tracks, the feeling is that your stomach may pop out of your body and fly away. Designers like to let you experience this feeling that your organs are about to fly. And actually, your organs are actually floating inside your body due to the negative G-force.

Although this is the name, the strength is not expressively negative, but a little less than the 1G we are used to. Engineers avoid using the negative G-force because humans don't usually respond well to it. Basically, in a really negative force, your brain and eyes would explode with blood pressure.

5 - Side hits

When you feel your cart rattle, it's usually the small side hits. With this, you also experience lateral G-force. In some toys, this is more common, while other engineers try to avoid the experiment. Excessive side-beating can have disastrous results, such as breaking bones or rupturing blood vessels in the brain.

6 - Heart exploding

Much of the other racing sensation is due to fear and adrenaline. Scientists have found that even healthy people can have their heart beating irregularly during a commute. But much of it is psychological, as most people have heart rate changes already expected to rise.

Scary-looking lanes can contribute a great deal to this kind of physical reaction: swinging before a fall or nearly colliding with an obstacle, or even seeing a giant creature jump over your car. All of this makes your heart race.

The Bush Gardens Griffon roller coaster has a 90 degree dive, six inversions and several near misses. However, according to Giles, if you close your eyes it feels the same as sitting in your rocking chair.
