Break is fun!

SO, because everyone else decided to take a break, my brain also decided to go off on holiday for a while. In that case, I've decided to make this blog post 100% fun (yet still on topic), and what's more fun and physics related than comics? Hope these tickle your funny bone, have a great break everyone!!! ...And finally, a comic that Mr. Fullerton would enjoy: Have a great break! Make sure to relax (and pretend that midterms aren't coming up)! --Alphageek

The Physics of Santa and His Reindeer

Credit to Mr. Powlin (who read this last year about the same time) and Snopes.com, where I found this humorous commentary once again. For those of you who did not hear this last Christmas or those who want to get into the spirit of the physics-filled holiday season, I thought I'd post this up for a few giggles. Happy Holidays, all! :snowman: No known species of reindeer can fly. BUT there are 300,000species of living organisms yet to be classified, and while most of these areinsects and germs

Pokemon physics... For a cookie!

*yawn* It's a beautiful Tuesday morning and you've awoken from camping in the jagged pass. You stow your tent into the key items pocket and continue on your trek to Lavaridge Town. You're on your merry way, thinking fondly of a dip in the hot springs, when the grass in front of you begins to rustle! Oh my, a Spoink appeared! Adrenaline pulses through your veins as you shout, "Go, McNugget!" (Mc.Nugget is none other than your lvl 98 torchic). You quickly break out your pokedex, which info

playground physics for a cookie

PRESSURE'S ON: First person to answer this correctly gets a cookie. :eagerness: You're at the playground with a girl you babysit, little Tori McTorque. Being 9 years old and devious, Tori took you wallet and threatened to spend your babysitting money on ice cream and root beer. Kids these days! You chased her over to the see saw, where she and her friend (Lil' Newton) sat happily on one side. You have to think of a way out of this! You don't want all of your hard-earned cash to go to waste, d

Little Italian men, weapons and screeching women

...can all be found at a fencing tournament! It's about time that fencing found it's way onto this forum. Fencing is an Olympic sport consisting of three weapons, epee, sabre and foil. In foil and epee, the opponent must hit their opponent's target area with their tip in order to score a touch. In sabre, the fencer may hit with the tip and/or the side of the blade to score a touch.

Physics and biology collide

So. I was reading my Biology textbook the other day and encountered something called "water potential." A simple summary of this term is water's potential energy , or it's capacity to perform work when free water moves from high water potential to low water potential. What? Physics in biology you say? Of course! :eagerness: Physics is everywhere. Let's define water potential in depth. Water potential is given by the equation water potential (symbol = Greek letter psi) = potential due to solu

The Physics of Tom and Jerry

In an episode of Tom and Jerry from 1948, Tom once again has his face smashed in from a falling object. This time, the offender was a half-ounce canary wielding circular cage parts. The bird unfastened the cage bottom and let it drop onto the unsuspecting feline below, making Tom's face into a pancake. How much force does this pan actually make? Could it really damage a cat's face? [ATTACH=CONFIG]513[/ATTACH] First, we must find the velocity of the pan when it hits Tom's face. We know tha

Happy Halloween!

[ATTACH=CONFIG]506[/ATTACH][ATTACH=CONFIG]507[/ATTACH] So. I was thinking of what to carve on my pumpkin earlier and thought, "What's something that'll scare the pants off of anyone, even high schoolers?" Bingo, air resistance. Many of us were shaking in our boots when Mr. Fullerton derived a few drag-related equations, but looking back they're not too bad right? Here's a little review. That long page really boils down to a few key equations: Air resistance = Fdrag = bv = cv2 , where b

Question: drag coefficient

How would I determine the drag coefficient of an organic shape, such as a blob of pudding or a chicken or a Looney Tunes character? I wanted to do a blog post on the terminal velocity of Wile E. Coyote falling off of a cliff. I went back into my notes and found the following equations: Air resistance = Fdrag = bv = cv2 VT= (mg)/b V = VT ( 1 - e(-b/m) ) Notice the constants, b and c. I turned to google, thinking that the constants would be relatively easy to find. It turns out, the

Fempto Photography Captures Light in Motion

So far, no other particle has been able to move at the speed of light. However, human beings are capable of seeing light move. Ramesh Raskar and his team at MIT have developed a camera capable of capturing light at 1 trillion frames per second. This method, called fempto photography, can take slow motion videos of light in motion. Watch the video for a better explanation but for those of you in a rush below is a summary of MIT's amazing research. As shown in the video, Raskar uses a laser to

Infrasound

Infrasound is sound with a frequency lower than 20 Hz. Human hearing registers sounds from roughly 20 to Hz 20,000, though under certain circumstances the body will hear/feel sound at a lower frequency than 20Hz. Though the human ear does not normally register infrasound, these inaudible waves effect our everyday lives. [ATTACH=CONFIG]530[/ATTACH] In Nature: Infrasound is produced naturally by severe weather and other forms of nature. Storms, thunder, volcanic activity, earthquakes,

How to become an autodidact

How to become an autodidact (defn: self-directed learner) :einstein) Monday, we were given a few packets of work, some written directions and a "finish this before the test next week." Weird. A class with no teacher? A few groups popped up to grab a computer, others buried their noses in the textbook, and some started chatting leisurely with friends. It's not that we don't have a teacher, it's just that for the next few days, we're our own teachers. For a few of us (including myself), th

Trampolines, Energy and Foxes (Oh my!)

Have you ever wondered how trampolines work? Anything fun or worthwhile has physics behind it, so let’s take a peek at the gymnast’s best friend: [ATTACH=CONFIG]497[/ATTACH] I hope you all enjoy my art skills. Read it and weep. :victorious: The magic behind a trampoline can be explained in terms of energy. Let’s say that a child is bouncing up and down on the trampoline. When the child is at a maximum height, his/her potential energy due to gravity is at a maximum. Because PE= mgh, wit

Why Mumble from Happy Feet stuck to his day job

Many of you are familiar with the children’s movie happy feet, about a whimsical penguin chick that just can’t stop dancing. Why don’t these birds fly instead of dance, you ask? Let’s use physics to figure out why Mumble is aerially challenged: There are four main forces involved in avian air travel: lift, weight, drag, and thrust. As shown by the diagram of a blue jay in flight (credit to http://www.lcse.umn.edu), lift opposes weight and thrust opposes drag. A bird is able to fly when lift

Happy New Year!

HAPPY NEW (school) YEAR EVERYBODY!!! I'm super excited for some serious Physics C. Just set up my account! I found this comic online and thought it would be a great way to break the ice: Hee hee. And of course I'll site my oh-so-credible source: http://memebase.cheezburger.com ...Although they did spell cheeseburger wrong. ^-^; And look, I found a fencing smiley face!:fight) --Geek out!
