Roller Coasters: The Physics Of Amusement Parks

Decent Essays
Roller coasters. An amusement park just isn’t an amusement park without one. They can give you the thrill that nothing else can ever do, and people love it. They’ll be going up one moment, down the next, and then upside down before you can blink. But how are these thrill machines able to do such amazing things?
The physics that goes into the construction of a roller coaster is a fascinating, complex process that many don’t understand. When the ride begins, you can usually hear chains being pulled. These chains are pulled by a motor which lifts the train of cars to the top of the first, and tallest hill. Once on the top of the hill, gravity takes over and no motors are needed. This is because while going up the first hill, the cars were able

When you go upside down during a loop, you don’t feel like you’re falling out of your seat, do you? As the car makes it way towards the loop, your initial velocity points straight ahead, the same angle the track does. As the cars enter the loop, the track guides the cars up, which in turn moves you up as well. At the top of the loop, gravity wants to pull you back down to Earth, but because of the cars inertia, you are pushed back into your seat instead of plummeting to your death. At the bottom of the loop, gravity and the change from downwards to horizontal once more pushes you into your seat.
Gravity also plays a major role in roller coasters. That feel of weightlessness you get when going down a large hill or going through a loop? That’s because of gravity. When a person feels that weightlessness, they are in free fall, which is where gravity is the only force acting upon them. Gravity also helps the cars gain speed going down a hill or coming down from a loop.
Gravity, inertia, potential and kinetic energy all play a key role in the development of a roller coaster. Roller coasters are literally built from the laws of physics. Without the knowledge of physics? There would be no roller
