To what extent is roller coaster designed by physical principles? --By Wayne Wang Introduction: The roller coaster is a popular amusement ride developed for amusement parks and modern theme parks. It gives people a strong sense of excitement and attracts millions of tourists throughout the world. In most people 's first impression, roller coaster looks not safe at all and it seems that the trains could run out of tracks and crash on the ground at any time. In fact, the average death rate of roller coaster is only 1 of 1.5 billion, compared with a 1 in 10 million chance of being killed by a plane rush . The roller coaster is well-deserved as one of the most reliable facilities in the amusement park. This such a low death rate is largely…show more content…
The third part is "Practical research", in which will pay more attention to the different structure between the actual roller coasters and the model, and how this works based on its physical need. Once I have evacuated all these issues, I will put forward some designs of new roller coaster, which has a higher level of entertainment compared with traditional ones. Part 1: Theoretical Research Section 1: Force A force is any interaction that, when unopposed, will change the motion of an object . Unsurprisingly, force plays a vital role and in another word, dominates the whole motion of the roller coaster. Therefore, it is necessary to understand how does force works on the roller coaster, and also physical principles related to this. Because force is a vector with magnitude and direction and it couldn 't be calculated by simply adding or substituting, how to calculate the forces exerted on the roller coaster become a significant issue in this section. Force acting on the roller coaster While the roller coaster is in operation, it is mainly affected by these following force: 1. Gravity(G): All objects which have mass located near the earth are influenced by gravity, so the roller coaster cannot be an exception. The direction of gravity is vertically down to the center of the earth, regardless of the motion of the roller coaster. The following formula is commonly
