When riding on a roller coaster your seatbelt is not what keeps you seated. Centripetal force is the reason you stay seated on the roller coaster. Throughout this paper I will explain what it is and the difference between centripetal and centrifugal force is. Then how it happens and how it works in those situations. Finally I will explain how to figure out what the centripetal force is in a problem using formulas to solve it. Centripetal force is ubiquitous every day, but we fail to recognize it. Centripetal force is a force that pulls an object moving in a circular path toward the center of its path. (1) Centripetal means it is a “center seeking” force.
This question can be answered by having an understanding of centripetal acceleration and centripetal force. Centripetal force described as “the force that keeps an object in its uniform circular motion.”5 The centripetal force in the Greek Waiters Tray is provided by the waiter’s arm.6 Centripetal acceleration is described as “the acceleration needed to keep an object moving in circular motion.”7 The centripetal acceleration is provided by the plate of the Greek Waiters Tray.
The biomechanical principle stability for a pirouette is primarily concerned with the center of mass
In this experiment we positioned a marble ball on a wooden roller coaster positioned on a physics stand in the sixth hole. Throughout the experiment, we used an electronic timer to record the time of the marble where it passed through the light beam of its clamp. We positioned the clamp at a certain point on the roller coaster and measured the distance from the marble to the clamp; the height of the clamp; and finally the time the ball traveled through the clamp. After we recorded these different figures we calculated the speed of the marble from the given distance traveled and the time. We repeated the step 14 times, then proceeded to graph the speed and the height. Next, we took the measurements of position of the clamp, height, and speed and calculated the potential energy, the kinetic energy, and the total energy. Total energy calculated as mentioned before. Potential energy is taking the mass (m) which is 28.1g times gravity (g) which is 9.8 m/s2 times the height. Kinetic energy is one-half times the mass (m) times velocity (v2). Finally we graphed the calculated kinetic, potential, and total energies of this experiment.
Tires are thrown from tires because the centrifugal force expels snow, rocks, and other foreign objects.
Ever wondered how roller coasters work? It’s not with an engine! Roller coasters rely on a motorized chain and a series of phenomena to keep them going. Phenomena are situations or facts that have been observed and proven to exist. A few types of phenomena that help rollercoasters are gravity, kinetic and potential energy, and inertia. Gravity pulls roller coasters along the track as they’re going downhill. Potential and kinetic energy help rollercoasters to ascend hills and gain enough momentum to descend them and finish the track. Inertia keeps passengers pressed towards the outside of a loop-the-loop and in their seat. Gravity, potential and kinetic energy, and inertia are three types of phenomena that can be observed by watching roller

Armature - Sometimes called a rotor. This is the part that spins. The armature can be either a permanent magnet or an electromagnet.
“Even though roller coasters propel you through the air, shoot you through tunnels, and zip you down and around many hills and loops, they are quite safe and can prove to be a great way to get scared, feel that sinking feeling in your stomach, and still come out of it wanting to do it all over again (1).” Thanks to the manipulation of gravitational and centripetal forces humans have created one of the most exhilarating attractions. Even though new roller coasters are created continuously in the hope to create breathtaking and terrifying thrills, the fundamental principles of physics remain the same. A roller coaster consists of connected cars that move on tracks due to gravity and momentum. Believe it or not, an engine is not required for most of the ride. The only power source needed is used to get to the top first hill in order to obtain a powerful launch. Physics plays a huge part in the function of roller coasters. Gravity, potential and kinetic energy, centripetal forces, conservation of energy, friction, and acceleration are some of the concepts included.
Roller coasters come in all sizes and configurations. Roller coasters are designed to be intense machines that get the riders’ adrenaline pumping. Ever since my first roller coaster ride, I knew I was hooked. I cannot get enough of the thrilling sensation caused by these works of engineering. When people board these rides, they put their faith in the engineers who designed the rides and the people who maintain and operate the rides. In this paper, I will bring to your attention a specific instance when the operation of one of these coasters came into question and led to a very tragic incident. From this, I will look into the events leading up to the incident and evaluate the decisions made by the people involved.
You apprehensively walk up the iron steps and onto the platform. You’re reluctant to go any further, but your friend eggs you on, saying, “It’s not that fast.” You step into the seat and pull the harness down over you. No, this isn’t the latest, greatest technological frontier. It’s a roller coaster. Since 1804 when the first wheeled roller coaster- called “Les Montagnes Russes”- was constructed in Paris, France, roller coasters have been a staple of adventure and fantasy among children and children-at-heart. But there’s no magic involved with these fantastic creations, there’s a plethora of forces and laws governing their every movement. From kinetic energy to inertia, roller coasters are intricate engineering marvels that function through the laws of physics. This is a look into those physics that result in a thrill ride unlike any other.

For centripetal force to happen a force must act on a object to make it move in a curved path. For example, when a force whirl a stone around on a string, a force must pull on the string to keep it from flying off in a straight line. The force applied to the object is the centripetal force. The faster an object spins the greater the centripetal force needed. The larger the radius of the object the smaller the centripetal force needed. The centripetal force is perpendicular to the motion of an object over a period of time, causing the object to move in a curved path. “To find the force you have to multiply the objects mass, m, by the square of its velocity, v2, and divide the product by the radius of the circle in which it moves.” (2013 encyclopedia) Another thing that affects centripetal force is centripetal acceleration. Here is an example from phys.uaf: “Say you are on a rollarcoaster, centripetal acceleration points towards the center of the circular path of the train, but is felt

...s proportional to the rotation rate. The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object's speed in the rotating frame.
Moment of Inertia is the measure of an object’s resistance to changes in the rotation direction. It is the rotational analog of mass for linear motion. The relationship of moment of inertia to angular acceleration is similar to that of the mass to linear acceleration. In the experiment, the scalar form or the mass of moment of inertia was used. The determination of the moment of inertia of a disk and a ring and to compare the moment of inertia of the solid disk rotated at two different axes: at the center and along its diameter are the main objectives of the experiment. After setting-up the equipment, the ring was placed in the disk and the friction mass is determined. Next, the addition of mass in the weight pan and the recording of its acceleration. Increasing the mass, four trials were performed and the experimental value of moment of inertia was calculated. Similar process were followed for the succeeding parts while considering the inertia of the disk rotated about the center and about its diameter after removing the ring. From the data gathered,
