How do loops on roller coasters feel?

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.

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.

The normal force however has a small magnitude at the top of the loop (where the rider often feels weightless) and a large magnitude at the bottom of the loop (where the rider often feels heavy).

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.

Not everyone finds the prospect of roller coasters enjoyable, to begin with — which could lead to the experience of stress not necessarily being positive for them. And just like people produce varying levels of endorphins and dopamine, the amount of cortisol generated can also differ from person to person.

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.

Physics/Mechanics Most roller coaster loops are not circular in shape. A commonly used shape is the clothoid loop, which resembles an inverted tear drop and allows for less intense G-forces throughout the element for the rider.

The same can be said for this phenomenon on roller coasters. “You feel very light at the top of loops, but heavier than usual at the bottom” (Boston University).

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.

According to clinical psychologist Judy Kurianski, high tempo rides expose us to “good fear.” Our brains perceive the drops and heart-stopping twists to be “safe” and “predictable,” so riding these thrill rides becomes therapeutic, especially as we scream out our anxieties.

Or go for the back seat because it offers more air time: your butt will hang in the air off your seat for much longer on those hills and drops. And those sitting in the last car in the line always experience the fastest ride and who doesn't want fast on a roller coaster?

Most glasses, if properly fitted, will not fall off your head during a ride, even those more extreme ones. That doesn't mean they definitely won't, however, so it is a risk. If I wear glasses to ride, I will hold onto them with one hand while going round the track just in case.

While most people do like to scream or shout their heads off while on a ride, it's not unusual to not make a sound on a rollercoaster.

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.
