As a little programming project, I am working on a basic physics engine that is intended to eventually handle spherical particles, walls, and springs. Currently, I only have particles that are fully functional. This is an open-source project and it is hosted at http://code.google.com/p/simple-swing-physics-sim/.
Mr. Fullerton showed us this intriguing instrument in class and I just HAD to find it for myself. The Theremin is a musical instrument that changes its pitch and volume based on the electric field surrounding two rods. The player's right hand controls the pitch and his or her left hand controls volume. In AP Physics, we normally calculate electric field using with a value of 8.85x10^-12F/m, but this only works for a vacuum or air. When the player brings his or her hands closer to the instrument
Progress on my app progressed smoothly last week, and as of last night, APlusPhysics is an official app on the Android™ market! The app can be found at:
Androidzoom.com, Appbrain.com, or Androlib.com.
Alternatively, one of these QR codes can be used to access the app's page (they are the same besides their size):

My recent coding endeavors have been channeled towards the development of an Android™ application for aplusphysics.com. I intend to create an app that serves as a smooth interface with the most important information present on aplusphysics.com and allows the user to experience the content quickly. While many visitors of aplusphysics.com are part of our physics class, I intend to make this app useful to anyone around the world that desires to learn more about physics.
So far, the app shows blo
Our AP-C class just had our multiple-choice/FRQ unit test on rotational motion, and with 20:20 hindsight I have a few tips for anyone looking to tackle his or her exam.
I. Know your formulas.
Make sure that you not only know the syntax of each formula, but also the meaning behind it. Formulas are always a representation of a relationship between two or more variables, and sometimes they will be tested in this specific manner. For example, with the formula Force(centripetal) = (mv^2)/r, the

When I first watched this clip, I couldn't believe it... After all, we have always been taught that an object in motion stays in motion unless acted upon by an external force, and I saw no strings attached to Professor Bowley.
As Bowley explains, the phenomenon of his rotations are caused by conservation of angular momentum. We all know and love the conservation of linear momen
First, here is some Swiss ski flying: (please note: for the purpose of this post, the mentioned video is not used for educational purposes, but instead serves as a really cool sight that is hopefully inspirational to readers)
And now for your weekly dose of physics...
Sometimes one may feel like he or she cannot count on anything, like life has no constants and is unbearably unpredictable. But humans have always taken one constant for granted: a n

Here's a question... how can one pool ball knock six others into the pocket? The answer: conservation of momentum. I like to think of the stagnant six pool balls as one single object. If the cue has mass 'M,' the object including the corner balls has mass 6M. Using conservation of mome
