What is the science behind amusement park rides?

The two most important forms for amusement park rides are kinetic energy and potential energy. In the absence of external forces such as air resistance and friction (two of many), the total amount of an object's energy remains constant.

A roller coaster demonstrates kinetic energy and potential energy. A marble at the top of the track has potential energy. When the marble rolls down the track, the potential energy is transformed into kinetic energy. Real roller coasters use a motor to pull cars up a hill at the beginning of the ride.

Basic mathematical subjects such as calculus help determine the height needed to allow the car to get up the next hill, the maximum speed, and the angles of ascent and descent. These calculations also help make sure that the roller coaster is safe. No doubt about it--math keeps you on track.

Our fight or flight response is activated which signals the rush of adrenaline. Those who are in favor of roller coasters tend to experience joy, happiness, excitement and satisfaction as this is what they wanted to feel. Therefore the psychological effect is positive.

Physical signs of fear such as a pounding heart, faster breathing and an energy boost caused by the release of glucose are known collectively as the “fight or flight response”.

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.

Summary. Students explore the physics exploited by engineers in designing today's roller coasters, including potential and kinetic energy, friction and gravity.

MORE DETAILS

Roller coasters are designed to run on two basic scientific principles: 1) gravity and 2) the transfer of energy. On Earth, gravity is the force that pulls objects toward the ground. The transfer of energy is what causes objects at rest to move and objects in motion to slow or stop.

Programmable logic controllers, usually three of them, monitor every aspect of a coaster's operations. They regulate the ride's speed, ensure that trains never come too close to one another, and alert human operators to technical glitches or track obstructions.

According to Kevin Hickerson, a physicist at the California Institute of Technology, “All the energy a roller coaster gets comes from the initial point it's cranked up to, and from there it just gains more and more kinetic energy.” The height of this first drop also determines the speed of the coaster cars.

The coaster tracks serve to channel this force — they control the way the coaster cars fall. If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates.

At the bottom of the loop, gravity and the change in direction of the passenger's inertia from a downward vertical direction to one that is horizontal push the passenger into the seat, causing the passenger to once again feel very heavy.

When the coaster moves down a hill and starts its way up a new hill, the kinetic energy changes back to potential energy until it is released again when the coaster travels down the hill it just climbed. Gravity and inertia are big players when it comes to how you experience the ride.

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.

With the movement and impact on the head and brain, riding them may result in headaches and migraine. For some people, the headache might go away after taking some painkillers and getting some rest, but for others, it could be a sign of a concussion or head trauma.

Studies have also shown that people with lower levels of dopamine, yet another feel-good hormone set off by pleasurable activities, venture away from thrill-seeking activities like roller coaster rides. In addition, cortisol, the stress-inducing hormone, is also triggered by roller coasters.
