  1. This is by far one of my favorite tricks to do along with butterfly kick and butterfly twists, (they link up really easily) but a parafuso actually shows how well the human body takes linear momentum and converts it to angular momentum but adding the upward force. The ginga (pronounced like jinga) is the building and wind up guard of this martial art. it has the leg back on one side and the arm back on the other. This basically gives range of motion to throw parts of the body into motion with more anticipation and control. But the first thing you'll notice is the 180 turn before he jumps. Thi
  2. In the classroom and around school I know that you mostly know me for my fedora, but on the karate floor i cant wear a hat so, I'm kinda stuck with these curls. Hilariously enough, sensei zak was joking about how my head always comes close to the ground on arials in front of the white belt class, then remarked "no, he just has a helmet for hair." I actually wanted to see that if my head and curls really were springs, what would the spring constant have to be on on giant spring to bounce me back, considering the curls come about an inch and a half off my head, and i mass in at about 70 kg.
  3. Okay, so in the quest for knowledge of physics i have come up with the worst sport of all time, physics surfing, clicking on physics in stumbleupon and trying to reach the end, gathering as much info as possible. This will never catch on though. So i decided to make a post about the physics OF surfing instead the Physics of surfing is actually kind of cool, relying on fluid resistance (much like that of air resistance) going upward in the circular motion of the wave (or arc motion of the wave) until the surfer's gravitational force matches that of the Frictional force of the water. The sp

  5. Okay, so for the last few months in physics we've worked on the kerbal space program, and although my group didn't really accomplish much, i kinda just wanted to finalize a few things that i learned. So there is my top 5 1) Kerbals are easily startled. meaning, these kerbals are astronauts that should have been previously trained and have experienced the forces existing in a spacecraft or spaceplane in the game. clearly this was bypassed as much as the safety measures on my rockets 2) Orbit CAN be achieved, around anything. if you think that you will randomly drift out to space when you
  6. Okay, so today i was skateboarding, thinking about blog posts, but also thinking about all the forces and such that go into just doing a few tricks. Such as the kickflip, where the board spins on the lengthwise axis (for those of you not skateboarding people). It needs the physics of the ollie, which is downward force on the tail, force upwards because of the fulcrum of one of the axles, and forward momentum from pushing with the front foot, for an inertial fulcrum that rotates the board up into the air. From there, the rotation is caused by a downward force on the edge of the board, but, the

Team Name: Wayne Enterprises Available Funds: $70,000 Vehicle Name: Straight Cash Money Vehicle Parts List and Cost: Cockpit - $1800 Tank - $1600 Asas - $1100 Controller - $450 x 3 Seperator - $600 Engine - $850 Parachute - $700 x 6 Wing - $500 x 3 Total - $11,200 Design Goals: Aerodynamics. Launch Goal: We are hoping to have a manned launch of at least 10 km. Pilot Plan: Fuel tank must seperate from the cockpit when the fuel runs out. Then the parachutes must be deployed directly afterwards. Illustrations: See attachment. Safety Rep: Liz Caceci.
  8. Okay, so recently i realized that there is actually physics applied to the way a string orchestra is organized. (minus the woodwinds in there its exactly what im used to) The larger instuments such as cellos and double bass take longer to speak because of the distance between the back of the instrument where thr sound peg produces resonence and the front of the instrument to where it speaks is greater. Therefore they need to be closer to the audience and more on top of the beat than the smaller instruments such as violins and violas. First violins are always in the front because they are alm
  9. This one is a more general physics post, but has some applications to parkour. A funny quote that i cant seem to find the source of "speed never killed anyone, its coming to a sudden stop. thats what gets you." thats actually a true statement, because so long as the speed is maintained or gently slowed the risk of injury is very low, but when speed is instantly accelerated to a stop, the impulse of the situation grows (the change in momentum over time increases.) This applies to parkour because no matter what someone does, they need to come to a stop somehow, whether it break bones in the
  10. As with the last one, this post focuses on the disspation of momentum in parkour, but this time, a little but simpler. This one focusses on the move called a dive roll. the move is essential because not only does it dissapate a lot of momentum over a short distance, AND have the abaility to cover large distances but it also allows one to land from a flip that has overspin beyond 90 (preferable beyond 135) degrees. A dive roll is basically a jump into a half flip in which the person lands on their hands, curls their back, abnd rolls out. It decreses the impulse by applying force to a
  11. no, probably not, ive tried 5 foot, but diving out of that is even scary :/ even with padded floor too.
  12. Okay, had a lightbulb moment that not many people have gone into the physics of some gymnastics moves and the physics of parkour in general. Hopefully you all know what parkour of freerunning is. Its a hobby and sport in which one tries to get from point A to point B (which can be anywhere from a couple of feet away to a half mile cityscape obstacle course) in the most creative way possible. This can include jumping over buildings, railings benches, or using them to one,'s advantage and finding footholds and cool tricking spots. But the tricks are designed to test the limits of the human body,
  13. This is a rare light phenomenon called a 'circumhorizontal arc' which in better terms is a rainbow in the clouds. It occurs when light is refracted and then split into the full spectrum just like that when moisture creates a rainbow after it rains. The slight differentiation in the wavelengths of red to purple light create a different diffration angle for each type of light, thus, the white light seperates into its visible parts: a rainbow. The clouds though, must be very high in the sky, as the rainbow we see after it rains occurs because the sun is on the opposite side of th
  14. Now that the first quarter is coming to a close, i would just like to take a physics and calc review (because most of the class is in calc-bc too, and for those of you who aren't *cough kaila cough* well, your loss. -In physics we did our first formal lab report which turned out to be a lot easier than expected. -We also built catapults, which in review was great and i'm glad that some of them didn't snap the arms from tension. -The Unit that we are currently in- Momentum and Impulse, is our very first alone unit, where we learn on our own, Mr. Fullerton will only come into play every once
  15. Okay, for any of you nerds or science lovers out over there (im on a blog about physics, there better e at least one of you besides me and my sister) you've probably heard about XKCD. FOR THOSE OF YOU THAT DONT KNOW: its the smartest joke site on the net, everything from politics, to math, to physics, to psychology, jokes abound, i HIGHLY suggest you check it out.: http://www.xkcd.com anywho, i found this one comic about the purity of the sciences and how there isnt just psychology, biology, chemistry physics and other things, their all subareas of other sciences. and science itself is
