the end is near!

Oh my gosh, this is the second to the last blog ill ever write!! how crazy, how sad. Actually i hope we have to write four more blogs..it'll really help my 30% quiz average :) I hope everyone is still praying for me and my miracle, you dont know how bad i need it!! I went to school on saturday, that is how much im hoping this miracle will come true! So above is a picture of me through a fish eye lens. Through a fish eye lens, lights refracts so that the photo produced is a wide-angle view that compresses images. A little reminder, refraction is the change in the direction of light as it passes from one medium to another or the "bending" of light.

Rainbows

Few more weeks of hell, literally. As doc said, nothing is free. I cant wait until APs are over. I would just like to say to anyone who is reading this blog, please pray for me these next weeks. I need a MIRACLE!!! Its not a joke, please!! Thank you :) Alright, so since Iris is the Greek goddess of the Rainbow, I decided to write about the physics of rainbows.. The fundamental process at work in a rainbow is refraction: the bending of light. Light bends or changes directions when it travels from one medium to another. This happens because light travels at different speeds in different mediums. Drops of rainwater can refract and disperse light in the same basic way as a prism. In the right conditions, this refraction forms rainbows. Rainbows are only images, not tangible, which is why no matter how hard you look or how far you travel, it's impossible to find the pot of gold waiting at the end of it. :(

The Last

My last cheerleading competition was this past weekend..so emotional. The last of everything is coming and its really sad. The last physics test is coming up, ohh my gaawwwd! My LAST chance to ace a test, i dont know if I can do it, I have no confidence in myself. I'll let you know how it goes though. Ok, last blog about weight (mass x gravity) and the normal force. I'm sorry, its the only concept of physics that I understand. So basically me and satoe (in the middle) are creating a normal force on demi (flyer) with our hands in order to keep her balanced. And as you can see on the outside Tori and Ashley are demonstrating torque as their straight bodies slow their rotation and also the force of gravity which pulls them back down. You could think of it like Ashley and Tori having a KE of zero at the beginning of the stunt and a potential energy equivalent to how much "energy" the bases put into the stunt which then converts to Tori and Ashley's Kinetic energy.

Lazzerrrs

Its fourth quarter my fellow followers! and then I'm to college..maybe ill start a college blog but maybe not. cuz ill be having too much fun!! Chee! So, last week we came back to school and tomorrow we have a test! physics is soooo fun! In the short amount of time we had, we learned about interference. An interference pattern is created by causing a beam of light to pass through two parallel slits to illuminate a viewing screen. Constructive interference of light waves accounts for the bright regions (called bright fringes) while destructive interference causes the dark fringes. The beam of light we used in labs were laser pointers. Yes, they do more than just blind people.
