How Roller Coasters Work

Who doesn't love the heart-pounding, facts-paced thrills of a roller coaster ride? Half the fun of the ride comes from feeling like you're going to fly right out of your seat - so why don't you? Read on to learn why taking a ride in a crazy coaster is about as dangerous as knitting with your grandma.

Up, Up and Away

A motorized chain pulls the roller coaster to the top of the first hill (that's why you hear that click, click, click sound). The first hill is always the tallest one unless the coaster has more motorized chains later on (listen for more clicking), which means that the first hill has the largest large amount of gravitational potential energy. What's that? It's the amount of work an object will be able to do with the energy it builds up from falling. The energy the roller coaster builds up from falling down that first hill will be enough to take you all the way to the end of the ride!


Accelerating Adrenalin

Now that the roller coaster has made it to the top of the first hill, gravity takes over. When the roller coaster goes down the hill, it speeds up at a rate of 32.15 feet (9.8 meters) per second squared. As it accelerates down the hill, the potential energy gets converted to kinetic energy. Kinetic energy is motion energy. Simply put, the energy changes from stored energy to moving energy. The weight of the roller coaster is pulled down by gravity (which means it's falling).


Newton's Law of Roller Coasters

Sir Isaac Newton (the dude who explained gravity) figured out the concept of inertia. No, inertia isn't a new game from EA, it's the law of physics that says that any object in motion will stay in motion until acted on by an equal but opposite force. When the roller coaster is at the bottom of the first hill, the kinetic energy is at it's biggest. Now that the coaster is whipping around loops and other hills, its energy is being lost to other forces like friction (energy created by two things being rubbed together) and air resistance. By the time the roller coaster gets to the end of the ride it has lost enough energy to come to a stop (usually with a little help from the brakes).


Please Stay Seated Until the End of the Ride

On some parts of this wild ride it feels like you're being pushed down, even though some of the time you're being pushed up. When you go down the hill the seatbelt or safety bars pull you down with the coaster. When you get to the bottom, you're still moving downwards but the coaster starts pushing you up again. The combination of these two forces holds you comfortably in your seat.

At this age you've just hit puberty and sure some of you might be more mentally matured, but you're thirteen, you're now being exposed to those kinds of things and your hormones might start kicking in and you'll maybe feel different ways to different genders and people but i really do think that thirteen is a much too young age to decide, and to "come out". I respectfully disagree. this is how I think of it. Being gay happens it's not like you wake up one day and you want to be gay. It justs happens, some people come out when there younger like around 13 ish others come out sometime later. It is a confusing subject and because it's only relitvaly new concept. I think personally people should just accept the fact because for many people it's hard for people to come out because of how people look at them. People should leave an open mind because with that at least you can help and give support to those who are struggling to figure this out. Not to take this personally everyone is entitled to their own opinions this is just an explication to hopefully make it somewhat clearer. I am not gay myself but i have many friends who are so I opinion will be different than yours which is perfectly acceptable.

It has nothing to do with their age or how mature they are.3. If its what they feel on the inside, thats never going to change with a age.4. dont use character quotes. rlly bothers me. Use ur OWN quotes or a pic or something, not a dead character from Harry Potter k?  it has everything to do witwit maturity and age. That is what we know as scients With*Science*Anyways. To the main question. Coming out is a deep decision. I'm not saying you aren't bisexual, but I'm not saying that this isn't too young. Being 13, I think you should at least wait till you are sixteen or seventeen to put a label on yourself. Remember, if you turn out to not be bisexual in the future and then tell your parents and friends, you might be laughed at or your mom saying "I told you it was a phase!"Maybe you should take a few quizzes and answer truthfully, or wait one or two more years before deciding who you are. But it's your choice.
