The 1900s: The Roller Coaster Like Start of the Century

Century Rollercoaster As in the beginning of the twentieth century, as in the first decade of instability and instability of the twentieth century, we see how America in the United States through massive battle adversity, Make the world a better. According to Times article "1900 Galveston Hurricane," "Arashi (Ripley 1)" About 8,000 Americans were killed, Texas's largest city was demolished on the ground. This sentence points to the most deadly hurricane that once struck the United States.

Today's lesson is the roller coaster and the science and technology behind it. But before we talk about physics we hope to share some of the roller coaster experience. (Some students listen to their explanation of their favorite roller coaster, point out some of the unique features of each roller coaster, such course related hills and loops, etc.) Who and how Do you know the job of a roller coaster? You might think that the inside of the roller coaster is equipped with an engine that enters into orbit like a car. This is true for some roller coasters, but most use gravity to move the car along the track. Do you remember a roller coaster where everyone is still on a big mountainside? If you look carefully at the course of the roller coaster (where the car is moving), you will see the chain on the first mountain road. You might think that it "catch up" with a car

Roller coasters are like trains. It consists of a series of connected cars moving on orbit. However, unlike passenger trains, the roller coaster does not have its own engine or power source. For most vehicles, roller coasters operate with only inertia and gravity. The only energy consumption occurs in the early stages of a ride when the car is pulled by the first mountain or "lift mountain". The truck starts with a stepping foot and accumulates latent energy in the roller coaster. The hills, valleys, twists and turns of the remaining tracks change the energy stored between latent energy and kinetic energy. As the train moves it gradually loses friction until it reaches the end of the trip.
