Welcome to AP Physics
The 2015-2016 has started. Welcome to AP Physics.
Here's some course information:
Grades: Approximately 50% Tests, 30% Labs, 20% homework
Tests: About twice a quarter, with semester finals also. Almost always items from old AP tests, which I’ll grade by their scoring system. This will cause me to adjust the overall grading scale. See below.
Labs: Although we’ll have weekly hands-on lab assignments, I’ll only have you write up formal lab reports about twice a quarter. (The first one will be due Sept. 8.) Many small lab activities will require answering 3 short reflection questions. Late labs are penalized at 10% a week.
Homework: Most homework will be submitted online through the web site https://quest.cns.utexas.edu/ It will be graded for accuracy, but on a sliding scale because I recognize that homework is practice and created to find mistakes. Students who have difficulty getting internet access should talk with me. Accommodations will be found. No late homework accepted except for excused absences.
Grading Scale: 100-85 A, 85-70 B, 70-55 C, 55-40 D, 40
Supplies:
Textbook
Notebook, or section of a notebook
Calculator
Here is the AP Physics C page dedicated to old tests.

Simple Harmonic Motion Lab
After doing the lab in class today answer the three standard minilab questions in your lab document.
Our purpose in doing the lab was to use our equation for the period of springs to determine if our arrangement of springs was parallel or series.
Here are the three minilab reflection questions.

Questions
- Describe the main physics related concept(s) you learned or practiced in the lab.
- How did the lab demonstrate or support these concepts?
- What else did you learn in the activity?

Rotations Test Review
Here are some problems from the textbook if you're looking for more practice problems before Thursday's test.
Ch 11 p 260
23, 41, 43, 51, 73, 83, 87
Ch 12

At the AP physics site you can find some good Free Response questions from past years. I recommend 2013 #3, 2012 #3, 2010 #2, and 2008 #2.

Help with Rotations Hmwk
We didn't have time in class to answer all of period Four's questions about the homework. Here are some general comments and hints about the questions we didn't get to.
14. Use the pivot point as your point of reference for determining torques. Remember that the Torque due to gravity will act at the center of mass or 0.5length.
19. Although I suggested at one point in class that this problem might be easier if you use conservation of energy, I think it's actually easier if you use the acceleration value you determined in Q17and 18. The relevant distance is half the original separation distance; that is where they'll meet. v2=vo2 + 2ax. (#20 probably still is easier to solve with conservation of energy, but you could do it the same way you do 19.)
22. Since I is the sum of the contributions by all the parts, you can add the I for a rod and the I for a mass (MR^2) to get the total I.
23. Xcm = is similar but different to I. This question is a review question of an equation that we used back in our momentum unit.
24. The question is asking us to solve for a fraction: Krot/K total. K total = 1/2mv^2 + 1/2 Iw^2. Since it's a true roll wr=v. Convert w to v and then substitute into the fraction. v should cancel out. The other values are givens.

Rotations Lab Guidelines.
Link to Lab Report Guidelines.
Put the lab report in your shared lab report document. This is the big one (200pts.) Do a good job and get it in on time.
