Physics: Roller Coaster The first rollercoaster was influenced by a sledding event and activity in Russia which included blocks of ice and going down a steep hill. Then American railroad companies capitalized on the idea for their benefit and business growth. Tracks were made in parks which included a type of circuit and were quickly refined and adjusted into better tracks. The thrill of roller coasters comes from its rapid acceleration and feelings of its weight gain and weight loss. Its unique tracks full of hills and quick circles make the experience very enjoyable. The mechanics of the coaster begins at the top where the potential energy is built and then it is then transferred into kinetic energy as the rollercoaster races down. Kinetic energy is then converted back into potential energy as the coaster moves up again and reaches another peak. Also, some mechanical energy is lost to friction. To find potential energy you have to take into account the mass, gravity

Common methods to get a rollercoaster moving are ways such as a flywheel launch, linear induction motors, hydraulic launch, and compressed air launch. According to data, roller coasters are very safe. The U.S. Consumer Product Safety Commission estimates that 125 amusement park guests required hospitalization in 2007 and deaths associated to amusement rides are close to two per year. According to an inquiry made by Six Flags, 325 million people visited parks in 2007. The report concluded that a visitor has a one in one-and-a-half billion chance of being fatally injured. Another problem people consider on a coaster could be the effects of whiplash which is triggered by a strong force and lack of safety. (http://www.cpsc.gov/)...
