Where do you feel the most force on a rollercoaster?

Because the mass of a roller coaster car remains constant, if the speed is increased, the kinetic energy must also increase. This means that the kinetic energy for the roller coaster system is greatest at the bottom of the largest downhill slope on the track, typically at the bottom of the lift hill.

The best seat on a coaster, then, is a matter of personal taste. If you love the feeling of weightlessness, head for the back. If you want the best view of the action, head for the front. The cars in the middle provide the weakest ride, but it's a good bet you'll still have a good time.

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).

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).

Other health conditions can make going on high-speed rides unsafe, including pregnancy, recent surgery, heart problems, high blood pressure and aneurysms, as well as the influence of drugs or alcohol.

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.

Based on the research and medical-professional recommendations, eating a light meal before riding a roller coaster is not a bad idea.

Keep your eyes open if you experience nausea. Some people will experience motion sickness while they are on a roller coaster. In order to combat this, you can keep your eyes open. This way you will be able to see what is coming and this will allow your body to predict the movements.

To avoid whiplash injuries, make sure your head is firmly planted against the back of the seat, and keep it there throughout the ride. Stay hydrated — especially in the heat — and take breaks between coaster rides to avoid dizziness, lightheadedness, or fainting.

The larger the mass, the larger the momentum, and the more force you need to change it. Mass does not make a roller coaster go faster but it does make it harder to slow down. This is why amusement parks test roller coasters with dummies filled with water.

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.

To help with this, don't close your eyes while on the ride! While it may seem scary to view the twists and turns you are going through, it will allow your body to sense the reasonings for why you are moving so abruptly.

Choose “safe” foods before and after your park visit. 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.

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.

As people age, they may feel the bumps and drops of a roller coaster more strongly or take longer to recover from dizziness after having been spun at high speeds. They may just not enjoy the thrill as much as they did as a kid.

Stay away from spicy foods or food you have never had before, and be sure to stay hydrated throughout the day. Hot temperatures and dehydration can make that queasy feeling worse.
