  1. Last weekend I crossed the border into Toronto, Canada for a "girls weekend" with my mom and sister. Our main purpose of going there was for a yoga convention for all the yogies of the world. While at this convention, we of course experienced tons of physics! When doing different yoga poses, we experienced the great phenomenon-gravity- at work. When "ohming" or saying "namaste" we experienced sound waves, and the vibration they produced so that we could here them. But when we weren't doing yoga, we somehow still experienced physics! By dropping tons of money at the 3-story mall, The Eaton Cent

  3. The reason why you get shocked more in the winter is because everyone has their heaters on which draws the moisture out of the air which causes the charges to build up and cling to us more since there is less moisture in the air.

  4. ...(But probably not.) In light of the holiday season, I bring to you a Christmas-themed blog post, with a pinch of love and some hints of gravitation. I came home from school today and stepped into the living room, astutely noticing that the Christmas tree had fallen. Obviously, the first thing that ran through my mind was that gravity did this. I mean, gravity's everywhere - it's a pretty likely culprit. You may or may not notice the lamp just above where the tree fell, but I believe it to be of great importance in this investigation. I have deduced that, at any time from 10:00 AM

  5. Physics is involved in pretty much everything in life. Throughout my school day I experience all kinds of physics. First period I have Italian where I sit down (along with the rest of my classes) and I am applying a force to the chair and the chair is applying a force to me because of Newtons third law. Second period when I get my math test score back I hit my head against the desk which is also applying a force to the desk and the desk applies one right back. Third period is art class where I gravity is pushing my eyelids down while I struggle to stay awake. Fourth period is APUSH which could

  6. So if you haven't heard, a rocket that was supposed to bring supplies to the International Space Station (ISS) exploded on October 28. Here's a short article and video talking about it: http://www.wired.com/2014/10/antares-rocket-explosion/. Obviously, this kind of sucks. The rocket cost about $200 million and now most of the supplies won't make it to the ISS. However, explosions are still really fun to watch, especially one that big and I don't feel bad saying that since the rocket was unmanned. Also interesting is that the rocket was made by Orbital Science, under contract of NASA. Thi

  8. Hello, my name is Max and I'm a senior in high school. Since everyone else is talking about the sports they play...I will too. My mother often asks me to stop playing tennis because it is such a physical sport, but I rarely listen to her so I continue to play at a varsity level. I can't have any pets except a boring fish because my dad is allergic to the fur on cats and dogs. At the moment I work at a restaurant called Hose 22 and I usually prepare food. I'm taking physics because it was recommended to me by my counselor. But I am excited to start physics because it looks like its goi

  9. Jelliott, I can really relate to your analogies. I too wish to become a beautiful butterfly, to grow and grow until I burst with knowledge. although I find some of your post humorous as intended, I think you struck on very important ideas. I think hard problems can be torture but on the other hand, that makes them that much more rewarding when completed.

  14. PCX is a workout area that I participate at weekly with my volleyball team. We go on tuesday nights to exercise as a team. I realized while watching videos that i recorded of the exercise's how much physics was applied into each activity. The vertamax that we use for jump training is full of physics. When you use the vertamax you put on a belt with two clips on either side of your hips. You then stand ontop of the vertamax (a square flat surface) and then attach the clips to different color resistance bands. With the vertamax at PCX you can either choose to use it for jump training or leg s

  15. My childhood, like many others, was spent watching many Disney Movies. One of my all time favorites was the Lion King- I never grew tired of it. One scene that always sticks in my mind is that once music number of young Simba and Nala and, of course, the scene of Mufasa's Death. (0:49-1:20) It can usually bring tears to even the toughest of teens, yes? As a child, this scene really never bothered me and, now, this sad scene seems to bother me so much more. Mufasa died a heroic, and untimedly, death by saving his only son. However, we should move onto the Physics now. How accurate

  17. I have a very large interest in bees, so for my first blog post I've decided to research how bees see colors differently compared to humans. Through my research I have discovered that the color spectrum of bees is shifted when compared to the color spectrum of humans. Visible light is part of a larger spectrum of energy. Bees can see ultraviolet – a color humans can only imagine – at the short-wavelength end of the spectrum. So it’s true that bees can see ‘colors’ we can’t. Many flowers have ultraviolet patterns on their petals, so bees can see these patterns. They use them as visual guides

  18. As advised by Mr. Fullerton, I did the Coat-hanger bubbles experiment to further understand flux! Pre-experiment preparation: First, in my closet I found a nice metal coat-hanger suitable for the trial. After attempting to reshape the coat-hanger, I learned that my hangers are very strong, or that I lack strength; so, I went to my brother's toolbox and grabbed pliers to help bend the wire into a slinky-like shape. My coil ended up having four turns. I then ventured into my kitchen to fill the sink with soapy water. With the bubbly solution complete, I was ready to start the experiment.

  20. While I was pouring ice cold lemonade for myself, I wondered-- "What would happen over time if I waited for a cup filled completely to the brim with ice to melt? Would the water spill over the cup as the ice melted? Or would the ice just melt leaving the cup still completely filled to the brim with no spills?" Huh. I had to test this out. I decided to use a cup filled with ice, and slowly poured water to the exact brim of the cup, and left a napkin under to see if the water would spill over after the ice melted. This was not enough for me. What if the cup were filled with ice and grape juice?

  21. Most people dont realize that there is science through playing a sport. Watching or playing volleyball is a great way to grasp the principles of physics. Understanding physics can be tricky if you just look at the mind boggling equations and such, but by connecting physics to other things, such as volleyball, physics can help you learn in an easier way. Gravity Gravitational force impacts every aspect of volleyball; whether you are serving, passing, or hitting. Gravity will effect every contact with the volleyball. When some one is going to serve, the server uses upward and forward force

  22. Last weekend at an honors interview at Roberts, I got to take a look in some of their physics labs. they had some fun things set up for us to check out. One thing was in a section called "physics and music". Sounds perfect for me, right? They had a bunch of wine glasses filled with different amounts of water. When you dipped your finger in some water and rubbed it around the edge of the glass, a specific note could be heard. However, if your finger isn't wet, it doesn't work. Why? Turns out, it is because there is too much friction between the finger and the glass when the finger is dry

  24. I have always wanted to see the northern lights, or Aurora Borealis. I've dreamed of travelling somewhere like Alaska or Finland to see them. In fact, there is a hotel in Finland with glass igloos so the vacationers can see the northern lights from their room. How cool is that?! Aurora Borealis mainly occur in high longitudes, but what exactly causes them? Turns out, it's from charged particles from the sun being expelled into space. The particles then come in contact with Earth's magnetic field. Then the Earth directs the charge to the poles and they collide with gas particles.

  27. In the spirit of Halloween, I created a spooky story that links together a couple of multiple choice problems from the Work, Energy, and Power exam that we took on Wednesday 10/25 last week. I hope you enjoy and Happy Halloween! A person pushes a box across a horizontal surface, but there is so much more to the story. The boy pushing the box across the creaking floorboards of a desolate hallway looks over his shoulder, fearing for his life.

  28. Everyone seems to skip leg day, not me!!! Leg day is by far my favorite, especially back squats (I can back squat 365lbs ladies ). While the back squat is a simple movement, it requires tremendous power in your legs. To perform a back squat you must place the bar on the back of your shoulders, lower your hips down bellow parallel and bounce out of the bottom of the squat . Once you bounce you will reach a spot in the lift where you will have to push down on the ground in order to push yourself and the bar up. The back squat involves a lot of momentum and a very big impulse. The impulse occurs

  29. The clean and jerk is an Olympic weight lifting movement where the lifter pulls the the bar from the ground, catches it in a squat, stands up from the squat and thrusts the bar over their head. The clean is performed by pulling on the bar off the ground with a high velocity, once the bar reaches about chest height, the lifter drops under neath the bar and catches it on his shoulder, and sits in a low squat position. The lifter then pushes up with a high velocity to stand back up, this is the clean. The jerk part of the movement is fairly simple. The lifter dips their hips down how ever far

  31. Prior to the beginning of overtime in last weekend's Packers v. Cardinals game, referee Clete Blakeman (definitely sounds like a fake name) attempted to flip the coin. Except he didn't. The coin did not flip at all. This prompted an outburst from Packers quarterback and insurance salesman Aaron Rodgers, who demanded a reflip. Blakeman obliged and the Packers subsequently lost. But how does a professional who has likely flipped hundreds of coins in his lifetime manage to screw up like this? Excluding potential sabotage, the only explanation for the lack of a flip is physics. A coin is flipped b

As center mid for my team, i am involved in almost every play, so i see in every way, shape and form how physics dictates the way the game is played. In our sectional game i had a beautiful aerial that went over everyone and straight into the circle where a teammate was and the play lead to a beautiful goal, which helped us with the game! Later i then realized that the aerial that i played was a perfect example of a projectile. Since the

  35. In Football Newton's 3rd law of motion is in action. When a running back is running head on against a tackler who is running just as hard and fast the outcome may vary. In games there are times where the running back gets hit so hard that he fumbles and other times the running back pancakes the tackler. One of the biggest factors is the mass because the forces are creating equal and opposite reaction. Force is applied and transmitted back. The player with more mass will generally hit harder.

Aside from hurting, what are the actual physics behind being unfortunate enough to get slapped? 1) Shown in slow motion, your face has incredibly present properties of intertia.

  42. The average aircraft will usually suck up a couple thousand feet in order to stop. The average single piston engine aircraft will take less, and a 747 will take much more (>5000ft). This creates a problem. Aircraft have insane amounts of momentum upon touchdown, and pavement isn't cheap. In addition, we can't have "mobile" airports for military use - so how are we able to deploy combat ready aircraft to anywhere in the world within a matter of hours? Well, we made mobile airports. And, they float! The aircraft carrier was first used in 1920. Essentially, it was a floating street wh

  44. The Quantum Physics of Alice and Wonderland Lewis Carroll had some interesting ideas in his works, especially in Alice in Wonderland. Alice falls asleep in a meadow, dreams of plunging through a rabbit hole, then finds herself too large and then too small. She meets new and bizarre characters on her way as well, including the Cheshire Cat, the Mad Hatter, the March Hare, and the King and Queen of Hearts. She experiences wondrous, often strange adventures, trying to reason in numerous discussions that do not follow the usual paths of logic. Finally she totally rejects the dream world and wakes

  48. Alpine skiing is one of my favorite things to do. And in thinking about the sport there is a lot of physics involved! Downhill skiing involves gravity and friction more than any other sport I can think of. The most important equipment to any ski racer is their skis, this involves an amazing amount of maintnance. Taking care of a good pair of race skis includes sharpening them after each use and waxing them as well. Waxing skis has a lot to do with the physics of the sport. What waxing does is it fills in all the little scratches and grooves worn into the skis which are unavoidable after use. H

  49. last year with Mr. Powlin we made some simple water bottle rockets after the ap exam. as we designed and built, we had a basic understading of what our rockets were supposed to look like, but for the most part were in the dark as far as the technical physics behind it. this is what i hope to explain. the common expression "this isnt rocket science" may have you expecting long equations with foreign symbols, however simple rocketry in its essence is counterintuitively pretty simple. for the type of rockets we made last year, only one condition is required for it to maintain its orientation, bei

  50. Hi Elliot, It does seem too easy! And I understand why you think the answer must be R, because I did too when I first read the problem. Unfortunately, it's not that easy. As the puck slides down the surface of the sphere, it accelerates both out and down. At some point, the out component of the puck's velocity becomes so great that gravity cannot keep it on the sphere. I encourage you to convince yourself of this by rolling a marble off a basketball or some other similar surface. (Rolling adds extra complexity to the problem, but the same principle applies.)
