Why do you feel heavy on a roller coaster?

At the top of the loop, the gravity force is directed inward and thus, there is no need for a large normal force in order to sustain the circular motion. The fact that a rider experiences a large force exerted by the seat upon her body when at the bottom of the loop is the explanation of why she feels heavy.

Air time has a strange effect on your body because your body is not completely solid — it is composed of many parts. When your body is accelerated, each part of your body accelerates individually. The seat pushes on your back, the muscles in your back push on some of your organs and those organs push on other organs.

Riders may experience weightlessness at the tops of hills (negative g-forces) and feel heavy at the bottoms of hills (positive g-forces). This feeling is caused by the change in direction of the roller coaster. At the top of a roller coaster, the car goes from moving upward to flat to moving downward.

The truth is that most visits to the amusement park are full of thrills, fun and are statistically quite safe. However, some amusement park rides, and especially roller coasters, are a significant cause of neck and spine injuries. While these injuries don't make the nightly news, they can slow you down.

People with high blood pressure and/or heart conditions are warned not to ride roller coasters because of the way they tax the cardiovascular system.

A. Airtime – A favorite term for roller coaster enthusiasts! It's used to describe the feeling created by negative g-forces which gives riders the sensation of floating on a roller coaster. Airtime or negative g-forces are most commonly experienced on a drop or at the crest of hill.

If there's a chance you might feel sick from the roller coasters and other rides, eat a bland breakfast (or other meal) before you go. You want something in your stomach to keep it settled, so choose bland foods like plain cereal, toast and crackers or scrambled eggs with nothing else in or on them.

It's the combination of lift hill and drop that are the scary parts for me. The lift hill builds anticipation so well, and then it's time for the hyper coaster level 90 degree descent, the first part of which occurs in total darkness.

Fear of roller coasters, also known as veloxrotaphobia, is the extreme fear of roller coasters. It can also be informally referred to as coasterphobia. Such a fear is thought to originate from one or more of three factors: childhood trauma, fear of heights, and parental fears that “rub off” on their children.

First, there are those long walks just to get on the roller coasters, then when you go on the thrill ride they're a good workout for your hearts and lungs. Roller coasters are good for stress relief, fighting phobias, and clearing your sinuses.

This high g-force can push heads down and have blood rush from your brain down to your feet, which in turn lowers the oxygen level in your brain, which may lead to grey outs, loss of peripheral vision (known as tunnel vision), or temporary blindness.

Balance is determined by your inner ear struggling to keep you aligned with a level plane so, no, closing your eyes will not assist whenever you're struggling with balance concerns on a roller coaster. Induced vertigo, however, is probably what's causing the most difficulties on a roller coaster.

At the top of the loop, when you're completely upside down, gravity is pulling you out of your seat, toward the ground, but the stronger acceleration force is pushing you into your seat, toward the sky. Since the two forces pushing you in opposite directions are nearly equal, your body feels very light.

Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars. The coaster tracks serve to channel this force — they control the way the coaster cars fall.

The sensation roller coaster riders experience that makes them feel like they're being pushed into their seats as they go through a loop is commonly referred to as centrifugal force, although it isn't a force at all. It's the result of observing one's motion relative to the object in which one is traveling.

“As far as an age limit, though, if you are physically healthy and up for the thrill, there is likely no greater risk for someone who is 60 than there is for someone who is 20.” The largest concern for those who indulge in roller coasters is the after effects.

There's a saying in the world of engineering: “If it doesn't shake it's going to break.” Roller coaster structures are designed to sway a couple of inches as the train goes racing by, especially in tight corners and high g-force locations.
