Maxwell's equations

Gauss's Law Gauss's other Law Faraday's Law Ampere's Law We've already done the first one which isn't that bad and I hope they're all that simple. Although I think the second one means magnetic field though a closed surface is 0. And Faraday's law means something with E field is equal to the rate of change of magnetic flux. And i have no idea what Ampere's law is saying.

Can we break the speed of light?

We have been told that nothing can go faster than the speed of light but what happens if we took a very long arm and rotated it around an axis. When a wheel is turning, the edges are turning faster than the middle in order to keep up. Lets say we took a laser pointer and pointed at the moon which is 384,400 km away, and flicked our wrist and a radian per second then the end of the laser pointer would be traveling 384,400,000 which is faster than the speed of light. So would the end of the laser

Fire Physics

What is fire? Fire is hot but where does it come from? Fire is the result of extreme heat, usually when organic chemicals combusted with oxygen(thank you chemistry) but where does the light come from? The light results from electrons absorbing the heat energy and jumping up energy levels like we learned last year and the light is produced when the electrons fall back down to their ground state. However fire can look different. The fire from Bunsen burners in chem or propane fires look a lot dif

Time to get started

With our last test we finished mechanics and official ended the first halve of the year. Surprising I didn't find the course as hard as I thought it was going to be. AP-B last year taught us most of the basics so we already knew most of the physics that we used this year. The major difference this year was the addition of calculus which isn't terribly hard compared to what Mr. Muz gives us. Also this year we aren't just given most of the equations and told to memorize; we are shown how to derive

The Physics of Happy Wheels

http://crazyarcade.wikispaces.com/file/view/dagobah_happy_wheels_DEMO.swf/182259727/dagobah_happy_wheels_DEMO.swf Before reading this you should play this game and warning it is pretty gruesome. This game has pretty good physics mostly although some parts of the game defy real life. For example the projectile motion is great because when you go off a jump or are sent flying by a land mine your body as well as the part of body that were probably blown off all have a parabolic path. Even t

Time to finish this. And This is just going to be all about how i feel the class is going so far. Right now I enjoy this class because it's not extremely hard. Yes the tests are hard but we're not learning anything new were just using derivatives and integrals on equations we used last year. I think the reason we think the tests are so hard is because we're not always taught everything that's going to be on the test and Mr. Fullerton leaves some stuff for us to figure out; which wouldn't be to

How Bullets fly

Skipping the intro, bullets gain all of their kinetic energy from expanding gas. When the trigger is pulled, the firing pin in the gun comes forward and ignites the gun powder in the shell. The chemical energy stored in the powder is then convert into heat which cause the temperature of the the air between the bullet and the shell to rise rapidly. Remembering the equation from last year PV/T=PV/T this shows that when the temperature increases ether the pressure or volume has to increase also. I

First planes, what's next?

Were as the idea for planes and the physics behind them make sense, the helicopter is completely different. In order to create the same lift as a plane does by getting air pass over the wings very fast, a helicopter has to lift by spinning it's rotor blades very fast. the same principle of fluid dynamics is responsible for the lift force on a helicopter. The blades on a helicopter are shaped almost the exact same as plane wing so that when they are spun they create a upward force on the helicopt

Flying like a bird only faster

In today's world we've almost all been on a plane at least once in our lives but it was just over a hundred years that the Wright brothers flew for the first time. The physics behind flight is not very complex at all but most people don't think about what's keeping them from dropping 30,000 feet in a 490 ton airplane. In the follow picture we see the all the forces acting on the plane and we all know that for the plane not to fall from the sky the net force in the up direction has to equal 0 so

One way only

Every Police/Law enforcement show has an interrogation where the criminal sweats it out while the detectives stand behind a one way mirror. How do this mirrors work? It's all about the light. Think of you're favorite interrogation room with a one way mirror in it. It's almost always bright in there while the room on the other side is kept dark. you might of thought like I did that it was to blind the suspects but in reality it's how the mirror works. A one way mirror is basically just half a mi

Finding the blips on the screen

The most important technology that came out of WWII was the nuclear bomb. But the second most important technology and probably the most used today is Radar. Every airport in the US uses Radar to track flights. But the physics behind this technology is very simple. It's the Doppler effect. A Radar system has two parts a transmitter and a receiver. The transmitter sends out a burst of radio waves. These waves go until it hits an object, say a plane and bounce back with a different frequency beca

Hurricanes and Cyclones and Typhoons

Today is a beautiful day for a hurricane and since we have no school we all get to sit home and watch the hurricane bear down us on the radar. Looking at the Google earth we can all see that Sandy looks like a giant cloud with a hole in the middle that is spinning counter clockwise. But why? The answer is the Coriolis effect. Now what the heck is that? "In physics, the Coriolis effect is a deflection of moving objects when they are viewed in a rotating reference frame." This is saying that an o

Catapults

There were many different types of catapults but every single one relied on the same principles. They all took potential energy, and transferred it into kinetic energy that sent the balls flying across the field or at least tried. There were different ways of storing the potential energy; spring potential energy or gravitational potential energy. Both proved to be very effective. However what really separated the best from the rest was the use of a slingshot. A slingshot increases the effectiven

Free falling

Afraid of heights? Well this guy isn't. Felix Baumgartner just made skydiving out of a plane look like a joke. In case you haven't heard because you don't get service or internet under the rock you live beneath, Felix just jumped out of a balloon 128,100 feet above the ground. Yeah that's over 24 miles. He also broke the world record for the fastest skydiver; reaching a velocity of 833.9 mph, faster than the speed of sound. I guess I have to talk about the physics behind this crazy stunt. If we

First post

I'm going to start off with why I'm taking AP-C physics because I think that's the best place to start. But anyways I'm taking AP-C because i last year AP-B physics was one of my favorite classes and i really enjoyed learning how the world around us works. Also applying the things that we have been learning in math for the past four years is really rewarding because finally there's a reason to learn it instead of just because the teacher says we have to in order to past the final. I am the k
