  1. 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: 1. Don't read the book. Seriously. People who say they read the book and found it helpful either a) did
  2. 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 the many that learned and memorized it at the beginning of the year for the first test, then forgot a
  3. 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 lacrosse involving torque, to hockey with rotational motion. But there is so much more. Physics was us
  4. As my second to last blog post ever (for a grade, you can't get rid of me that easy!!!), I thought I should simply talk about how physics is in everything we do. so Here are some summer activity examples most people would not think of: Playing on the playground (teeter totter, slides, swings, etc) Computers/ video games Cell Phones Flying a kite Water gun wars Swimming Driving Packaging for college (Force required to pull/carry it, increasing mass) Baking/ throwing cupcakes Sports (Baseball, football, soccer... btw you have to be playing not watching sports) Shopping (carrying shopping bags, t
  5. So my dog just growled and I thought I should do a blog post on her since I cannot think of any ideas. I was just playing fetch with Pearl in my house, which has hard wood floor (the real kind). Pearl ran on the area carpet onto the hardwood, but when she tried to stop, she ended up skidding past the ball into the fireplace (its just a hole in the wall made of brick so she was unharmed). So here's the play-by-play: When Pearl was running on the carpet, she was able to get enough contraction to accelerate forward. Once Pearl hit the hardwood floor, she couldn't accelerate or decelerate as
  6. 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 cathedral ceiling and other architectural projects. Seems like I'm not the only one who thinks it looks
  7. 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 politics of it. There are floating bridges in existence, which use multiple air compartments so th
  8. 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 time:? vf= vo + at 0= 5.13 + -9.8t 5.13= 9.8t t= .5235 --> Total Time: 1.047 seconds Y= vot + .5at
  9. So Friday night was Senior ball!!!! I hope everyone had lots of fun. I sure did, and like many of the girls, came in high heels. However, I tried my best to stay in them for as long as possible, dancing in a knee-length dress in 3-inch heels. It's a lot harder than it sounds. When you wear high heels, the center of body mass vertically shifts upward. Because of this shift, your posture becomes unstable, and increasingly so as the height of the heel increases and with increased amounts of movement. Therefore, with the significant displacement of the center of mass and dancing, which involves lo
  10. Kow jumperd over the mun? so bad.
  11. I know who it iss.......the clerk is write with an answer of 2.453243752... or 2.5. Beatcha Charlie!
  12. Looks really cool. I would say youre good to go, lets just hope your pilotting skills have improved.
  13. you're good to go but you are definitely wasting money.
