Mock AP Testing Schedule

posted Apr 13, 2018, 1:45 PM by Barbara Fortunato

M 4/16 - Th 4/26

Here's the schedule:

M 4/16 - E&M Free Response Questions Mock
W 4/18 - E&M Multiple Choice Mock

W 4/18 11:59pm - Mechanics Review Video due to Google Classroom

F 4/20 - Mechanics Multiple Choice Mock
Th 4/26 - Mechanics Free Response Questions Mock 

For all the days in between, you'll be studying by practicing past AP questions of your choice.  If you are taking the actual AP, I highly recommend doing recent tests from AP Central, as the test was changed in 2011.  Otherwise, practice any questions that you can find.

2: Th 4/12, 4: Th 4/12

Exam on additional topics in mechanics TODAY!

Homework:  If you're taking the AP Physics C exam(s), start studying!  Aim to try to do at least 2 past AP problems.  Even if you're not taking AP Physics, you can start studying for your mock AP exams.  

How can you solve problems involving heavy ropes?

posted Mar 30, 2018, 9:36 AM by Barbara Fortunato   [ updated Mar 30, 2018, 9:53 AM ]

2: T 4/10, 4: W 4/11

Today, we'll do some AP Problems that involve the concept of heavy ropes.  

Required:  2009M3, 1975M3

If you finish these, you may look online (check your Google Classroom "About" page) for more practice problems for your exam next class.

Homework:  Study for test on velocity dependent forces, gravitation/orbits, and simple harmonic motion on Thursday, April 12th.  Finish your lab write-up, which is due Thursday, April 12th, same day as the test.  The test includes this material, so it's important that you understand the lab.

How well do you understand the physical pendulum?

posted Mar 30, 2018, 9:23 AM by Barbara Fortunato   [ updated Apr 11, 2018, 4:41 PM ]

2: M 4/9 lab, 4: T 4/10 lab

Today, we'll design an experiment to find the moment of inertia about the center of mass of an odd shaped object.  In order to do this, you'll have to understand the motion of a physical pendulum.  Once you finish taking data, you'll finish your brief individual write-up of this lab.  Do your write-up on paper which you can turn in in hard copy.  Your analysis should include a labeled sketch of the set-up, at least one free body diagram, sentences about what you did and why, and calculations necessary to find the moment of inertia about the center of mass.  YOU MUST DO AT LEAST TWO DIFFERENT TRIALS to verify your calculation of the moment of inertia ABOUT THE CENTER OF MASS.

With any time remaining, you can finish any required problems from topics up to this point, or if you've already completed all required problems, you can watch the homework video. 
 
Homework:  Test on velocity dependent forces, gravitation/orbits, and simple harmonic motion on Thursday, April 12th.  Finish your lab write-up, which is due Thursday, April 12th, same day as the test.  The test includes this material, so it's important that you understand the lab.  Watch the following two videos - they're the same problem with two different methods which are both useful: 
  • Method 1:  small mass dm, constant applied force, finite distance y
  • Method 2:  whole mass remaining, changing applied force, force constant for very small distance dx

How can we characterize simple harmonic motion?

posted Mar 22, 2018, 6:43 AM by Barbara Fortunato   [ updated Mar 28, 2018, 5:07 AM by Barbara Fortunato ]

2: M 3/26 lab & Th 3/29, 4: W 3/28 & Th 3/29

Today, watch the following two videos on simple harmonic oscillators with springs and pendulums.  Alternatively, learn about simple harmonic oscillators using the available media of your choice - textbook, internet, etc.

SHM: Springs (Dan Fullerton)

SHM: Pendulums (Dan Fullerton)


Small angle approximation:


Then, in groups, apply what you know and solve problems with simple harmonic motion:
    Required:   Oscillation AP Problems (2009M2, 1990M3, 1999M2)

Homework:   Make sure you are caught up with the videos in preparation for the lab tomorrow.  Also, make sure you've at least done 2009M2 which is the first problem in the Oscillation AP Problems packet.  Test on velocity dependent forces, gravitation/orbits, and simple harmonic motion on Thursday, April 12th.   March 29th.  If you know you're not going to be in school that day, please plan to take the test before you leave - 3rd our on Wedneday, March 28th.

2: T 3/27, 4: T 3/27b lab

We'll start with some time to finalize your lab write-up, although it should be almost all the way done already.  If you're already done, you can work on the velocity depending force AP problems from the previous post.  

Then, LAB QUIZ Today on the coffee filter lab.  

Homework:  Finish all velocity dependent force problems.

Check out this page for a better understanding of "angular frequency" ω  (aka frequency of oscillation) and how it relates to the angular speed ω   we already studied in rotation:


How can we characterize air resistance?

posted Mar 11, 2018, 8:31 AM by Barbara Fortunato   [ updated Mar 22, 2018, 7:45 AM by Barbara Fortunato ]

2: T 3/20 lab, 4: SNOW DAY W 3/21 lab Th 3/22 & F 3/23

Today, we will study "velocity dependent forces."  We'll get back into the swing of mechanics by doing a lab where we investigate the concepts of air resistance (drag) and terminal velocity.  You'll take advantage of available technology by using motion sensors or by analyzing videos you take and graphing position vs. time and velocity vs. time in LoggerPro.  In the end, you'll see how drag force relates to velocity.  

Homework:  Lab in journal due Friday, March 23rd.  LAB QUIZ on Friday!  Make sure to answer the following questions in your lab write-up in addition to the usual stuff:
  • Describe air resistance.
  • What equation relates air resistance to force of gravity on the falling object? (think sigma F)
  • What are some real life situations in which a person observes air resistance?
  • What are some situations in which air resistance is a problem?
  • What are some variables that affect air resistance other than velocity?
  • Why does this procedure work as a controlled experiment? (What else are you holding constant)?  
Watch the following video on velocity dependent forces. At time 6:00, pause the video and practice solving the differential equation on your own. (It will probably be faster than watching the whole video.) After you make your best attempt, fast forward to see if you were right. Then, at 17:00, listen to the notes at the end. Be prepared for a daily quiz next class.
