Unfortunately, this is the last of the Batman Blog Post series. However, I saved my favorite for last: Batgirl.
When Barbara Gordon first became Batgirl, it was without the consent of Batman; in fact, he didn't even know about it until he saw her in costume. So, Batgirl had to purchase and create her own costume and weapons, including a jumpline to swing around Gotham like Batman. However, she got the wrong jumpline, and would have died, but Batman cut the rope and Robin saved her. Why would
I must have a thing for thinking about blog posts in the middle of the night. So last night I woke up at 3:00 am because of my sore throat, which makes it extremely painful to swallow, cough, yawn, etc. So, as I lied in bed unable to fall asleep, I thought about the mythbusters episode I watched about making someone wet the bed by sticking their hand in water. But what stuck out to me was that they used the frequency of the brain waves to determine how deeply asleep Adam and Jamie were.
As y
Ok, I think everyone knows that sequels are rarely as good as the original, but I think The Physics of Roof Trusses II is way better than the first, but that's mostly because I thought that this roof truss was way cooler. So the very last thing I did in my independent study was build a scissor roof truss. The reason why I like this one so much is because of the awesome shape, even if the angles were butts. Anyways, it usually spans up to 20 meters or 65.51 feet and is most commonly found in cat

So a few weeks ago was my birthday (delayed much?) and I have some really awesome friends who got balloons for me. So nice, right? Well as I am looking at the balloons, I noticed one of them had a limit on it. What this super awesome friend of mine did was write happy
th
Birthday!! Totally cool huh? Turns out the limit equals my age, which is really cool and NERDY!!!!
Thanks Alpha Geek!
Let's cut to the chase: Life is full of decisions, especially as a senior in high school. Over the years I have noticed that many people have a difficult time making decisions, so I have decided that I am going to release my decision-making secret, the reason why I can so easily make decisions: I use math.
Making decisions is like momentum (p= mv) , two opposing forces collide, changing the directions of the objects. To make things simple, let's refer to only two balls (aka choices). Each ball
Hey people, i know that it's not a fan favorite but i haven't done a blog post on my independent study. Recently I finished a roof truss called a double cantilever (or a type C truss), a model for the technology room. This specific type of roof truss is used mostly in commercial and industrial buildings. It spans on average 16 meters, or 52.5 feet. That's really all I know, but I'm really proud of my work which I think is very cool. Hope you guys agree!!
(Again, sorry about the extreme size of
As most people know, I can't stand cats, and constantly joke about kicking them. So, I thought it would be appropriate if I did a blog post on it!!
I am by far not athletic, so top speed I could probably kick a soccer ball at 15 m/s or 33.354 mi/hr (This is the average low for kids 11-17 ). I also don't kick at much of an angle, but for this we'll say 20 degrees.
So here's the math:
y- component:
height: ?
acceleration: 9.8
velocity initial: 15sin20= 5.13
velocity final: 0

So if people are actually reading these you probably already know that I am currently sick and wide awake thanks to the wearing off of "nighttime" robitussium... which frankly I am not sure how to spell. So I thought I would do ANOTHER BLOG POST!!! :worked_till_5am: Hey, Ive got so much physics in my life (voluntarily) I'm up to my ears in it, so Ive got a lot to say. Which is why I like these posts. Instead of confusing my mom with what she calls the science of the ABC's (no joke, I told her I
Once a month MIT sends me an Admissions newsletter about new things going on at MIT. One of my favorite articles is about how the students turned the outside of a building into a giant tetris videogame. While the students used more engineering than physics, their was still the components of electric circuits needed to create such an awesome hack (which is a prank MIT style). So here's a video of their creation, and all I have to say is that I WANT TO PLAY!!!!:eagerness:
Originally this was going to be about Batman's utlilty belt, but then I had so much fun things to talk about with the batarang I changed my mind.
Well, to begin with, the batarangs are NOT a sold piece of hardened steel alloy. It actually folds in half. Another thing to keep in mind, the batarangs are not designed to return to Batman, hence why the design is not very similar to a boomerang. Also, Batman has multiple kinds of batarangs. So when Batman throws one at a rope, he has one for cutti
Ok, does anyone know how all of Batman's stuff fits into that belt?
So to start off with, Batman's belt has quick-release covers that can be locked and unlocked with a swipe of a thumb for easy access. Just a fun fact. And, there is a collapsable grappling hook in the belt buckle. Which brings up an interesting fact. Batman uses a de-cel monofilament jumpline cord for his hand-held grapnel gun. The reason for his choice in rope is because it can hold up to 400 lbs, making it possible for Batm
Ok, I have been working really hard to finish the AP Physics Review Packet, but I haven't really compared answers with anyone else. So I thought it would be helpful for everyone if I posted my answers. I personally think they are right, but if you have a different answer, SAY SO!!! I would gladly compare notes to find the correct answer, helping everyone out. If I missed any questions, let me know.

Wow. That title is a mouthful. Kinda like the equations in this unit because THERE ARE SOOO MANY. So I am going to help everyone (and myself) and create a list.

F= I x B
FM= FC --> r= mv/ (qB)
Velocity Selector: FM= FE --> v= E/B
FB= ʃI (dl x
B= μoI/ (2πr) μo= 4π e-7

Hope everyone had fun on Halloween! I sure did. But after handing out about 12 bags of candy and eating some in the process, I began to wonder what is the physics behind eating too much candy. Obviously there is the dreaded "tummy ache", but thats biology, I want to know the physics!
So this is how it works: When you consume sugar your body creates energy, lots of it. After eating so much candy after a while, you've got a lot of potential energy just dying to become kinetic energy. When the pot
So as most of you know the election is just a few days away! YAAYYYYYY!!!!! Just kidding. I for the most part don't pay too much attention to politics, but sometimes I find the topics interesting. I, however, do not find this years election very interesting. Too much bad mouthing and he said he said to ruin each other's reputation and poll numbers. Because for the most part I do not care for either candidate, I have decided to use physics to create an equation to help people like me choose a pre
As promised, I looked into how fast the Batmobile would go on a frictionless plane instead of the roads of Gotham. To compare the difference, I used everyone's loving friend, Energy.
uk= .8
aB= 60 mph in 2.4 seconds (after some conversions....)= 11.17 m/s
mB= 4500 lbs (FYI, I was wrong, a tank weighs 135,000 lbs)
F-Ff= mBa
mBaB- ukmBg= mBa
(4500) (11.17) - .8(4500) (9.8)= 4500a
a= 10.376 m/s
They may not look like a big difference; well, its not in the short distance.
x= 1 mile= 160
Ok, I gotta admit, that last blog post stunk like my dog's farts. In fact, other than the physics of faradays cage, they all have been pretty bad. Well, I am going to tell you what the best and the worst have in the blog posts.
The best:
Humor is a good thing. Physics at times can be rather boring, and if you couple it with some humor, it can be more entertaining for the viewers.
Have it on an interesting topic. Let's face it, a bad topic is a bad blog.
Connect to the "real world." Dont jus
After talking so much about my favorite engineering field, I decided to create a QUIZ to find your perfect field of engineering. A nerdy-version of a personality quiz. WIN.
By the way, please post your results, I am curious to know how accurate my quiz is.
1. Other than physics, what is your favorite subject?
a. Biology
b. Chemistry
c. Technology
d. Math/ Calculus
2. What do you like to do in your free time?
a. Logic puzzles
b. Tinker
Ok so I think it's fair to say that no one wants to read a textbook, especially a physics one. Me personally, the words just kinda go in one ear and out the other. So here's my tip on how to read the textbook: Don't read the textbook.
A lot of you are probably thinking, "YES! I've been doing that all year!" Well, there's more too it. Mr Fullerton is right when he says the textbook can be very helpful, but the way I "read" the textbook is by doing the problems. Obviously you can't just open the
Ok, I'm going to be honest... I am waiting for my hair to dry before I go to bed, and I have nothing better to do than to do a blog post. This might take a while.
Well, in the meantime, since this was the last day of real physics c, I decided to say the top ten tings I have learned from taking this course (fyi, they are in no specific order, only in the order they pop into my wet head)
1. Rotational kinematics/energy/momentum/ everything is without a doubt the coolest subject in the course.
Next year I will be going to college for civil engineering and I can't wait. One of the people in my physics class is always asking me if I'm going to build an Atlantis. Ever since, I have been interested in the idea of building a floating city on water, called seasteading, which is what Atlantis was before it sank supposedly. Current engineers are looking into the idea, using a similar set up as oil rigs, which are held up on platforms that go down to the bottom. The issue is the cost and the p
So senior year has finally come to an end and we all are saying goodbye. So I thought I would discuss the physics of senior year. The year has had so much physics enwrapped in it, in and outside the classroom. We got to use physics in physics c (duh), calculus, and technology for those who take these classes. With a basic understanding of physics, these classes became easier to learn and master.
Outside the classroom, physics was used by every athlete in the school in some shape or form from la
I'M BAACCCKKKKK!!!! As stated in my last entry, though it be several months ago, college wont stop me from blog posting. And with my new found wisdom of college life, I thought I should give some advice to the new prisoners, I mean physics C students.
The first thing you learn in physics c is vectors, along with the dot and cross product. LEARN, MEMORIZE, MASTER, REPEAT. Not only will they continue to pop up throughout the year in physics, they will continue to pop up in college. I was one of t
So, I am aware that you guys have been doing E&M for a while, so while this is a little late, it should still help. Now, I know that not everyone likes E&M (just ask Mr. Fullerton how much I liked it ). Well, I too am taking E&M (for the third time), and I have finally cracked the code for success (took me long enough). Now I, the girl who cannot do the right-hand rule (still), is not only understanding E&M, but solving it CORRECTLY.
How you ask? Well, here are some tips:

Hey fellow physics people, this is my first blog!!!!
So I am taking this independent study on statics (nonmoving objects such as buildings and bridges) and my first project is a poster on the truss unit for the Principles of Engineering class. I gotta say, physics B is definitely playing a part in this project like the ups= downs idea for equilibrium. But when I was planning the poster I couldnt remember the most simple things, like finding the moment first in order to find the torque on the
