=> Since we opted to use class time to work on our group projects, the video listed above includes all of the information that was going to be addressed in class. If you have any questions after viewing this video, please post a response on the blog. There should be a comment balloon just to the upper right of this post.
=> This video is a short demonstration of the consistency of Time Dilation and Length Contraction.

On Friday, 4/13, we took a look an analyzing series RCL circuits. I created this Excel document that allows you to adjust inductance, capacidance, and resistance to see how the response changes in the circuit. You will need Office 2010 version to view the file.Resonant Workbook
I also was able to use a screen capture program in attempt for yo to see a short clip of the changes that take place. Resonant Freq video
Level I Thermal Physics
This entry currently contains a term sheet and a test solution from the past
=> Here is a list of terms that you should be able to define. It is more important for you to be able to understand these terms than to recite a textbook definition. Comment on this blog if there are terms/definitions that you do not understand. A Thermal Physics Terms
=> AT Thermal(08) This is the solution to the test that was sent out via email.
=> On May 8th, we solved a sample problem in preparation for the test involving ice melting due to heat conducting through a glass. the problem on the board was photographed and made into a short 3 minute movie. The movie is here in mp4 format Conduction class problem and in WMV Conduction class problem.
=> Heat of Fusion Activity: Please read the process below to ensure completion.

View the video in either format (mp4 Melting Ice) or (wmv Melting Ice). Headphones are recommended as there is audio. I would also recommend pencil and paper for note-taking.

Write a lab report (50 points) including Purpose, Procedure (including all equations and derivations of equations), the data in graphical form, data aanalysis to determine the Latent Heat of Fusion of water, and a conclusion. You should be within 30% of the accepted value. The data is available here as an Excel table. You may plot in Excel (Need slope) or in Graphical Aanalysis. (Excel data link : melting ice). Submit your report as a printed hard copy.

Open the shared Google Doc “Melting Ice Discussion” and post an entry. You will receive 30/30 points for making a relevant entry, 20/30 for a non-relevant entry. You may post more than once. The guidelines for this entry will be on the Google Doc.
Long Term Project
This is for all classes. The Long Term Project is replacing the Final Assessment Project as part of a pilot program which is running for this year only. Everyone will recieve a hard copy of this material, however a PDF version is available here, and now.

Rotational Dynamics Unit Level I
Statics
Sample problem #1. This file is a PDF. The solution is not yet available, althought we have completed this in class.
Horizontal Bar supported by a pin and a cable
Sample Problem #2, “The Opera Singer”
Static problem 2 This is a PDF of the problem.
statics problem #2 solution. This is a video created from still pictures, including explanations.
Sample Problem from class. This is a video of a problem completed in the Pd 4 class including friction as a force acting.
Meter stick on board This video is constructed from still photos and explained with a voice-over.
Below is an advanced problem using the “Method of Joints.” This extends beyond the scope of our course, but is a good exercise in problem solving. At least give the file a look, as the concepts are actually easier than what we do in class.
Static problem 3 PDF showing and explaining the “Method of Joints.”
Class on April 3, 2012, we solved some sample problems with statics. Some still photos of the one problem were collected and and video was created. This video can be accessed by clicking this link. Static sample problem from class #1
Rotational Dynamics
Linear term to angular term transformation. This video was captured during class. The purpose was to show how all of the linear equations can be used with angular motion. This video was captured in a year prior to this year, so the class was “different” than what was experienced this year.
Rotational Inertia This is a video captured during class from year’s past. Rotational inertia is explained, and an example is worked through.
Rotational Dynamics solutions to the worksheet distributed on March 26 in class. *NOTE* I found an two errors with #2 (and #5..Thanks McKenna)!!! I failed to include the angular velocity. The answer should be 11,000 Watts. ALSO!!! Find the error in #5…the answer should be 8.4 m/s….
