Derivation of velocity equation with Air Resistance

The derivation of the equation for the velocity of an object experiencing air resistance was long and tricky.  I've prepared a PDF of it with notes about the steps.  You can find it here.

https://drive.google.com/file/d/0B54jRZBDezIHSnB6UHFaWkRXMlE/view?usp=sharing

There is a minor mistake in the middle of the second page.  Twice I write dt instead of u, in the denominator of the right hand side of the equation.  This is in the section that I've labeled "now collect terms and integrate."

Flying Pigs

Take measurements of the pig's mass, and of the radius, period and the angle of the string's deflection from vertical as it flies in circles.  Calculate the tension in the string in two different ways.  (1.  based on the weight, 2. based on the net force.)
Do the 2 methods come within 5% of each other?  If not, what went wrong?

Answer the 3 minilab questions in your google doc lab file.

Lab 2 - Projectile Motion

AP Lab 2 – Projectile Motion.

Your Task:

First derive an equation for the range of a projectile based on the launch angle and the initial velocity.

Then determine the initial velocity produced by a projectile launcher by gathering data about the launch angle and range, graphing them, transforming the graph to make it linear and then interpreting the slope of the graph.  While not easy, this is your task.  A final part of the task is to qualitatively describe how air resistance affected your results and based on that how do you get the greatest range when there is air resistance.  

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.

Three things to do to prepare for the class.

If you were not in physics last year you will want to take care of these three things.

Setting up an Online Homework Account:
Please go to this link and start an online homework account. Choose "I need a UT EID" below the red button. In the next windows and pages answer the questions to get an ID number from the University of Texas.  After you submit your information it will send your ID code to your email account. With this code you will will sign in to my class and start the first assignment. You may proceed to sign in now or bring your EID code and password on Wednesday. On Thursday/Friday we will log in as a class, I will start accepting your enrollment and we will start the first assignment.

This is how to sign in:
Return to the link above and log in.
You will then need to select a class based on a unique number. For AP Physics the unique number is 223. Enter the number and then select "look up course info". Scroll down by clicking the arrow on the window that appears through the many other classes designated with that unique number until you find AP Physics (Grant High school 2014 Fall). It will probably be the only one. Select it and then select request enrollment.

I will have to admit you into the class. The next time you log in, after I admit you, you will be able to use the "select course" and "select assignment" windows to start the Kinematics homework.

Creating a Google Document for submitting lab reports:
Students will submit their lab reports to me via google docs.

Please make a google account, and make a single google doc and share it with me.  All of your labs will go one this single document.  Please give me the ability to edit it so that I can add comments and insert my scoring rubrics.

Please use the naming format - lastname.firstname.APphysicsperiod____

Don't use my normal email to share it.  I made my google account back when pps emails went like this:

emedley@pps.k12.or.us

Installing LoggerPro on your home computer:
As a Grant High School student you have the right to install Logger Pro on your home computer.  The following installation links will require a password to decompress.  You will need to get that password from me.


Logger Pro 3.8.7 with sample movies (Windows)

Welcome to AP Physics

The 2014-2015 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. 15.) Most lab activities will be accompanied by a short worksheet to complete. 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
Protractor
Graph Paper
