Physics Questions About Roller Coasters 10

1. At the beginning of the execution, the roller coaster's train relied on the thrust of a mechanical device to push it to the highest point, but after the first descent, there was no longer any device to power it. In fact, from this point on, the only "engine" that drives it along the track will be gravitational heat, that is, it is composed of a continuous process of conversion from gravitational heat energy into kinetic energy, and from kinetic energy to gravitational potential energy.

2. The first type of energy, i.e., gravitational heat energy, is the energy that an object possesses by itself because of its position, which is derived from its height and acceleration due to gravity. For roller coasters, their thermal energy reaches its maximum at its highest point, that is, when it climbs to the top of the "hill".

When the roller coaster starts to descend, its potential energy is constantly decreasing (because the height drops), but it does not disappear, but is converted into kinetic energy, that is, kinetic energy.

However, in the process of energy conversion, heat is generated due to the friction of the roller coaster's wheels against the track, resulting in a small amount of mechanical energy (kinetic energy and potential energy). That's why the subsequent hill in the design is more mechanical energy than the height of the hill at the beginning.

3. The feeling of descent is strongest in the rear compartment of the roller coaster. This is because the last car passes through the highest point faster than the car at the head of the roller coaster, due to the gravitational pull acting on the center of mass in the middle of the roller coaster.

In this way, the person in the last car is able to reach and cross the highest point quickly, and thus there is a feeling of being thrown away, because the center of mass is accelerating downward, and the wheels of the rear car are firmly fastened to the track, otherwise the small car can be derailed and thrown out when it reaches the vicinity of the summit.

The situation is different in the front compartment, its center of mass is "behind", and for a short time, although it is in a state of decline, it has to "wait" for the center of mass to cross the high point and be pushed by gravity.

4. When you reach the "Circle of Madness", the roller coaster traveling along the straight track suddenly turns upwards. At this point, the passenger will have the feeling of being pressed onto the track, because an apparent centrifugal force is generated. In fact, on the circular track, a centripetal force is created due to the interaction of the rails with the roller coaster.

This circular orbit is slightly elliptical in shape and is designed to "balance" the braking effect of gravity. When the roller coaster reaches the highest point of the circular track, it will in fact slow down, but this phenomenon will diminish if it is less curved. Once the roller coaster has completed its journey, the mechanical brakes bring the roller coaster to a very safe stop.

The speed of deceleration is controlled by the cylinder.

1. The roller coaster is affected by gravity, support, traction and friction in the traction and ascent stage.

2. In the process of free driving, it is affected by three forces: gravity, support and friction.

3. At the highest point, it can be affected by the three forces of heavy blind hidden force, support force and friction force, or it may only be affected by gravity.
