The principle of roller coaster and the experience for passengers

 

The roller coaster is an exciting entertainment tool. Many people are fascinated by the thrilling and thrilling thrill. If you are interested in physics, you will not only experience the thrill of adventure while riding a roller coaster, but also help to understand the laws of mechanics.
       1. In fact, the motion of a roller coaster contains many physics principles, which are used skillfully in the design of roller coasters. If you can experience the effects of energy conservation, acceleration and force intertwined, it feels amazing. You don't need to use your brain to deal with physics this time. Just tighten your abs and protect your stomach. Of course, if you are limited by your physical conditions and mental capacity, you ca n’t experience the feelings of the roller coaster yourself. You may wish to stand by and watch the roller coaster ’s movement and the rider ’s reaction.

2. At the beginning, the small train of the roller coaster relied on the thrust of the catapult or the chain to climb to the highest point, but after the first down, there was no device to power it. In fact, from then on, the only "engine" driving it along the track will be gravitational potential energy, consisting of a process of continuous conversion of potential energy into kinetic energy and kinetic energy into gravitational potential energy.
      3. The first kind of energy, that is, the gravitational potential energy is the energy that an object owns because of its location. It is generated by the gravity interaction between the object and the earth. For a roller coaster, its potential energy reaches its maximum when it is at its highest point, that is, when it climbs to the peak of the "hill". When the roller coaster begins to fall, its potential energy is continuously reduced (because the height has dropped), but the energy will not disappear, but will be converted into kinetic energy, which is the energy of movement. However, in the process of energy conversion, heat is generated due to the friction between the roller coaster wheels and the track, and a small amount of mechanical energy (kinetic and potential energy) is lost. This is why the subsequent hills in the design are slightly shorter than the hills at the beginning.
      The last section of the roller coaster is the most exciting gift the roller coaster gives to brave passengers. In fact, the feeling of descent is most intense in the rear compartment of the roller coaster. Because the last car passed the highest point faster than the car at the head of the roller coaster, this is due to the gravity acting on the center of mass of the roller coaster. In this way, the person in the last compartment can quickly reach and cross the highest point, which will create a feeling of being thrown away because the center of mass is accelerating.
