How I Had To Leave New York

It’s been ages since I’ve seen you!! I still can’t believe I had to leave New York to come down here,  but it really wasn’t my choice. My dad had to have his work down here apparently there was no other option. But you know i’d be there hanging out with you right now if I could. Well, at least we can still write to each other until I come back to visit over winter break.

Man, I miss that cold weather, it’s so hot in Florida. ALL. THE. TIME. Not much of anything new has been happening, it’s taken some getting used to since I have no friends here :( but i’ll manage. I mean things are getting better, yesterday I got to go to Disneyyyyy World!! Remember when we took that trip to Disneyland? In California? Ahh that was so much fun. But anyways, I went with this guy that I’ve gotten pretty close to.

Nonono I know what you’re thinking, he’s definitely not my boyfriend but yeah his name is Kam, and you know how I told you that I had a cousin down here in Florida? Niya? Yeah her too. Oh and Kam’s friend, I think his name was Derek. Basically we took a trip to Disney World since they insisted that I absolutely needed to go, because I’ve never been of course.

I figured out that they have separate parks there and it’s not just a giant castle.

I mean I did get to see the giant castle, but that’s not the point. They recommended that we should go to “Magic Kingdom” and “Epcot” so of course I was totally down. My parents dropped off me and Niya and shortly after we met up with Derek and Kam to get out tickets into the park. From the start it was pretty cool, everything was really fancy and I hadn’t seen anything like it before. The very first thing I had laid my eyes on was this huge sphere. And when I say huge I mean HUGE. I have no idea what it was but I soon learned there was a ride inside of it!!! It’s called Spaceship Earth, and it is a geodesic sphere that serves as the symbolic structure of Epcot. Not only that but it had this amazing pattern of triangles on it making it look like a golf ball. I’ll show you a picture of it in this letter. It’s a whole 180 feet (55 m) and it starts 15 feet above the ground, I have no idea how a structure so big can be held up by a few pillars and doesn’t just roll away. The diameter is a whole 165 feet (50 m)! So inside the ride would go around on the inside edge of the ball, going in circles up until the top.

So I wondered, “How far were we actually going on the inside.” For this I would have to find the circumference. With a 165 diameter, the structure weighs as the guild said around “16 million pounds.”  How would I get the circumference of something so big? Well I know the circumference would be the length of the circle if it were opened up and straightened out into a straight line.  So Circumference is achieved by multiplying pi ( π = 3.14 )  by the diameter circle. 165 times  pi would be 518.4 feet (158 m)!!!  Wow I sure have to go see that again later. That was enough of Epcot for now, next, on to Magic Kingdom. This is the one we’re always seeing pictures of everywhere. Right when we get there we walk around until the four of us are in the middle of the park trying to figure out which section to go to. We were all arguing about which one because there were five different ones and none of us could agree on the same one. So instead we decided why not just ride the little kid carousel that we were already standing next to?

I waited in line with all the little kids and their slightly agitated parents. Looking  at the carousel, I noticed it was very pretty with lights around the top and the horses going around in circles in the  f  gold paint and designs they were decorated with. I also noticed some were moving faster than  others, how was this possible? Wouldn’t they have to go at the same speed since  they’re all attached to the base? I pondered for a moment as I got on top of my horse as Kam got onto the one next to me and Derek in front. The ride started  going pretty slow but then I looked down and saw that each line of horses from  the center would go in different speeds because they were in separate circles!!  It takes each horse the same amount of time, that would allow them to  circumnavigate the entire circle. The horses on the outer edge of the carousel have to move more the inside horses in the same amount of time. This  shows that the riders on the outside have a faster linear speed than those at the closer to the center. Tangential velocity is the liner speed of something that is moving within a circular path. A point on the outside edge of the carousel travels much more distance in one complete rotation than a point nearer the center.

Wow I was thinking about it so much I totally forgot about what was going on, on the ride. Well, after that ride we finally agreed on going to Tomorrowland, the part of the park designed to be like the future. A lot of it did focus on space though. Kam pulled out his phone to show us that we had our fast pass tickets reserved for Space Mountain… IN 2 MINUETS! We had to run all the way there and made it just in time. Luckily we didn’t have to wait in the long line with everyone else but only had to stand for a few moments. I knew this was an indoor roller coaster but I wasn’t scared, well not as scared as Niya at least. Derek told us that this ride has all kinds of loops and curves, then Niya really started to worry and didn’t want to go, complaining that “What if the ride stops in the middle of a loop?! Or or orr worse… What if it falls off? How can it stay on there?!” So I had to  explain to her that the ride is always on the track because its connected to it, and is  not just lose. Not only that but what really keeps people in their seats while a roller  coaster goes through a loop isn’t just the restraints, it’s centripetal force. The feeling we get of being pushed to the center of the rotation is called the “centripetal force”.

This force is what allows the cart to keep moving on the roller coaster track. When something goes in a circle, which is basically what a roller coaster does while it swiftly glides through a loop, the moving cart is pushed inward to what’s known as “the center of rotation” or what would be the center of the loop or circle. Imagine the middle part of a Ferris wheel that’s holding all the spokes in place, but in this case is not seen. The part highest off the ground or sideways, the part farthest from where the cart enters the circle, the gravitational force goes inwards and that results in there being not as much of a need for a normal force to meet the net amount of centripetal force. When the cart enters the circle, or where we are closest to the ground, the gravitational force goes outwards, so now its required that we would need a strong upwards normal force, to meet the centripetal force that’s necessary. Centripetal acceleration is also involved in moving in a circular path.  This means that, centripetal acceleration is also an important part of a roller coaster. Centripetal acceleration focuses toward the center of the circular path the roller coaster is going in, but is felt by passengers as a force pushing them to the outer edge of the circular path.

The higher the ride cars velocity, the greater the centripetal acceleration.   This also means that the smaller the curve of the path being traveled, the greater the centripetal acceleration.  Because of this, many high-speed roller coasters use curved tracks rather than the flat ones that are safe for slower speeds. After much convincing we finally got to get on the ride. It was amazing! It made me feel weightless! It was dark too so I wasn’t even sure of what was going to happen. It was fun though. We also went back to Epcot. Later, we went around going on every ride we could find, eating good food, and having a great time. In the end the four of us went sat down on a bench after the long exhausting day and watched the fireworks. That’s pretty much it, it was a long day. I wish you were there too to experience it, but maybe next time you can come down and visit me? I hope so at least. Write me back as soon as you can, and let me know how you’ve been. Bye bye… see you soon.
