Class ID Number (CID)


You need to use your CID to get credit on your homework and labs.  If you do not have, or if you do not remember your CID for this class, please visit http://gardner.byu.edu/cid/.  With your CID you can check your scores online.

Quiz Remote


You will be issued a remote the second day of class.  You need to register your remote number to get credit for your quizzes.  Your five digit remote number can be found on a label in the battery compartment, probably following the letters TXC.  To register your remote, simply go to http://gardner.byu.edu/123f2/quizid.html and fill out and submit the form.

Class Handouts


Class handouts are in adobe acrobat (.pdf) or web (.html) format.  If you do not have an adobe acrobat reader, you can download one here.  Web format documents will load faster, but acrobat files are better for printing.

Practice Exam

 


The practice exams is purely for your benefit, and is not to be turned in.  It will help you get an idea of how I write exams to help you prepare for the first exam (for the following exams I assume that you will already be familiar with my exam-writing style, so I've only generated a practice exam for exam 1).  The solution is included with the exams.  This is an actual exam from a previous semester.  The problems cover randomly selected material and do not cover all of the material you will be expected to master before taking your exam.  I recommend that you do not look at the practice exam until you have done most of your studying for the exam.  This way the exam will give you a good idea of how well prepared you are, and how much more work needs to be done before taking your exam.

Homework and Exam Solutions


Homework and exam solutions will be posted on the classes Blackboard page, available through route y.  The unit 1 solutions are also posted, at least for now, at https://gardner.byu.edu/123w2/solutions/index.html.

 

PowerPoint Presentations

 


If you would like to review some of the PowerPoint presentations I have shown in class, go to my PowerPoint Presentations page. The slides have been converted so that they can be viewed directly in Internet Explorer.

Tutorial Lab

 


Go to http://webs.byu.edu/tutorial/106sched.html to see the tutorial lab location and schedule.  All of the T.A.s can help you, but the ones who "specialize" in Physics 123 are listed at http://gardner.byu.edu/tas/123tutors.html

Cool Free Software --- useful for learning and for term projects

bulletSpectrum Lab
This is a really cool audio program.  It will "listen" to a microphone on your computer and display the waveform of the sound as well as its spectrum.  It also does waterfall plots.  What's more, you can use it to measure frequencies, and even to generate different tones.  I used to link to several programs to do these things for my students, but this one does them all --- and extremely well!
bulletMy Java Applets and Applications
Feel free to play with the programs that you use for the walk-in-labs at any time.  You can learn a lot from them.
