trigonometry allows designers to see how steep and long its descents will be from a given height and over a given distance. This allows them to alter the height and length of a descent exactly to produce the maximum permissible thrill.

Trigonometry is a key tool for calculating these factors and making the roller coaster as safe and thrilling as possible. Trigonometry functions allow designers to work out the angle and the length of the slopes that the height and position of the peaks will generate.
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.
Introduction. A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track.
Most roller coasters run by the Law of Inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started. The student's roller coaster started at the top of a big hill.
If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates. Since an object in motion tends to stay in motion (Newton's first law of motion), the coaster car will maintain a forward velocity even when it is moving up the track, opposite the force of gravity.
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.
The thrill of a drop is the product of the angle of steepest descent in the drop (in radians) and the total vertical distance in the drop. The thrill of the coaster is the sum of the thrills of each drop. The total horizontal length of the straight stretch must be less than 200 feet.
On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. All moving objects possess kinetic energy, which is determined by the mass and speed of the object.
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.
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.
The conversion of energy from one form to another (for example from potential to kinetic) is virtually never 100% efficient. That is, some of the energy escapes in other forms.
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.
