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
9, 15, 17, 29, 45, 57, 65, 69

http://apcentral.collegeboard.com/apc/members/exam/exam_information/8039.html

At the AP physics site you can find some good Free Response questions from past years.  I recommend 2013 #3, 2012 #3, 2010 #2, 2008 #2, and 2006 #3


Here is a good practice AP test with key.

First Semester Review Options

Here are some questions from the end of Chapters 7 and 8 about Energy, Work and Power and from Chapters 9 and 10 about Momentum and Impulse

Ch7.  15, 23, 33, 37, 51
Ch8.  23, 35, 39, 49, 55, 69, 89
Ch9 15, 21, 39, 47
Ch 10 19, 27, 47, 53, 55, 67, 71

Here is a link to the AP Physics C Course Description.  On pages 16-25 they list the learning objectives in careful detail - a giant list of what we should learn in this class, and the only real list of what concepts and problems might be on the test.  We have covered sections A- D at this point.

Here is a link to a site with numerous practice tests, each 2-20 MC questions about topics of a particular type.  After you do the questions they will show you solutions.  It will ask you many times to sign up for their tutoring services, but it never seems to require you to do it.

Here is a link to a good practice test with answers.  FR Q #1f about center of mass contains material we haven't covered yet.

https://www.crashwhite.com/apphysics/materials/practicetests/practice_test-5-momentum.pdf

As always the link to the practice AP FR questions remains a good source for practice with answers, and there is the new set of homework questions.

Here are some FR questions from past tests with an emphasis on the material we've covered recently
2014 #2,  2012 #2, 2011 #1, 2011 #2, 2009 #1, 2009 #3, 2006 #2, 2003 #1, 2002 #3


You can also use UT quest to make a customized review set of questions, focusing on all of the homework questions that you missed the first time around.  Follow these steps  (copied from their help menu)
  • Customized Review 
  • To help you review for an upcoming test, use the Custom Review option to create customized reviews that focus on your weakest areas. Choose Grade Summary from the left menu, then the Grades by Subject Area link to see the Custom Review option.

More Practice Problems for force Unit

Here are some additional problems from the book:
Ch 5  p101-107:  33, 35, 37, 39, 43, 49, 51, 57, 59, 63, 65
Ch6  p123-129:  7, 17, 35, 37, 43, 49, 55, 57, 61

Also Sample problem 6.8 on p 117

Also here are some FRQ from past years that might serve as good practice, though parts of them rely on energy concepts that we haven't learned yet.

They're from

http://apcentral.collegeboard.com/apc/members/exam/exam_information/8039.html

2015 #1
2014 #2  skip part 1
2013 #2
2008 #1
2006 #1 all but last part, and #2  all but last 2 parts
2003  #1 parts a, bii

Finally, here is a practice test with answers that looks good.

Review for test

Here are some questions from your physics book to think about if you want some more practice   The answers are in the back of the book.

p73-80

7, 15, 21, 29, 35, 43, 59, 63, 71, 77, 83

Remember the lab is also due on Monday the 26th.

Oh, and here is a link to a pretty good test (with answers at the end) written by a different teacher somewhere.

AP Lab Two

AP Lab 2 – Projectile Motion.
Your Task:

In this lab you will be determining the initial velocity of a projectile from its range as a function of its launch angle, and then analyzing the effects of air resistance. Roughly the steps will be as follows.

  1. Derive an equation for  R(θ, v)
  2. Find  a way to manipulate your axes so that a graph with axes based on θ and R should produce a linear graph, the slope of which will allow you to determine v0.
  3. Collect enough good data, that you can determine v0 within a tolerable range.
  4. Graph and analyze your data, looking for v0 and a description of the effects of air resistance.


As before copy the questions from the link below to your lab document and answer the questions.
