Although I have tried my best to make my roller coaster model close to the real one, I have to admit that there are a number of features which could not be revealed in the model. In this part of the research, I will pay attention to some details of design of real roller coasters and further research on some roller coaster of new types. Composition
Generally speaking, a complete roller coaster system contains several sub-systems, which include lifting system, braking system, track system computer operating system and so on. Here I will illustrate two main sub-systems of roller coasters: lifting system and braking system.

The majority of the parts of roller coaster are also designed to ensure its safety, although most passengers cannot notice the existence of these designs.
1. wheels assembly:
For a roller coaster, the function of the wheels is not only allowing the train to move forward, but also sticking the train tightly on the track in order to make sure that the train doesn't leave the track when any accidents occur. For now, most roller coasters adopt three-wheel-design. Each wheel contains an underfriction wheel, a running wheel and a side-friction wheel . As shown on the image above, the top two wheels are running wheels, which are used to bear the weight of train on the track and keep the train running. The running wheels may leave the track when the direction of the acceleration is upwards, however, the wheels on the bottom could prevent the train from the leaving the track. These wheels are underfriction wheel. In addition, Side friction wheels lie on the side of the track and they could hug the sides of the rail. These wheels help the train stay in the center of the two rails to keep the train from derailing.

The other two rails are used to control the spin of the seats which allows the seats to move forward or backwards to add excitement.
Conclusion
Overall, all parts of my research have all be geared towards the topic: To what extent is a roller coaster designed by physical principles. Designing is the first step of construction of roller coasters. In order to ensure that completed roller coaster could run smoothly, the running state of the train must be considered in advance.
Clearly, physical principles have a irreplaceable role in almost every part of the roller coaster design. Then main physical principles involves Newton's Law of Motion, the law of conservation of energy, force analysis, and material mechanics, and these principles could be put into practice in either huge or tiny designs.
In addition, through my roller coaster model, I noticed that there are some designs which haven't be put into practice but feasible from the perspective of physical principles. Therefore, in the future, the style of roller coaster is likely to become more and more diverse when its corresponding techniques are
