A new 12 question assignment has been posted on the UT site. IT is due at 10:00 pm on Jan 2, the last night of your break.
To prepare for the assignment you should follow this link to a video lecture by Walter Lewin who is an engaging MIT professor. The lecture lasts for most of an hour and gives you a sense for a college physics class, albeit a great one. In a part of this lecture he digresses extensively into Newton's Law of Universal Gravitation. You can ignore this part for now, though we will return to the ideas. You should also look to chapters 7 and 8 in your textbook for explanations and sample problems. Much of sections 7 and 8 (and the material in the lecture) we will cover after you return, though it is good to read them in advance. The homework questions will largely come from the first parts of both chapters.
I will check my PPS email over the break, but not every day probably.
Good Luck.

Unit Two: Kinematics Continued
Goals: The list at the end of this entry come from the AP standards. We’ll be focusing on the bold ones in this unit.
Big Dates: Test - Thursday. Oct. 28
Lab – Projectile Motion, due Wed. 10/19
Homework:
Quest problems due Monday, 10/17 at 10:00 pm, and
Tuesday, 10/25 at 10:00 pm
Worksheet labs for 10 pts each on Thursday, 10/6, and Wednesday, 10/19
1. Motion in One Dimension
a. Students should understand the general relationships among position, velocity and acceleration for the motion of a particle along a straight line, so that:
(1) Given a graph of one of the kinematic quantities, position, velocity, or acceleration as a function of time, they can recognize in what time intervals the other two are positive, negative or zero, and can identify or sketch a graph of each as a function of time.
(2) Given an expression for one of the kinematic quantities, position, velocity, or acceleration, as a function of time, they can determine the other two as a function of time, and find when these quantities are zero or achieve their maximum and minimum values.
b. Students should understand the special case of motion with constant acceleration so that they can:
(1) Write down expressions for velocity and position as functions of time, and identify or sketch graphs of these quantities.
(2) Use the equations to solve problems using one-dimensional motion with constant acceleration.
c. Students should know how to deal with situations in which acceleration is a specified function of velocity and time so they can write an appropriate differential equation and solve it, incorporating correctly a given initial value of v. (We'll do this one in our Forces Unit.)
2. Motion in Two Dimensions
a. Students should know how to deal with displacement and velocity vectors so they can:
(1) Relate velocity, displacement, and time for motion with constant velocity.
(2) Calculate the component of a vector along a specified axis, or resolve a vector into components along two specified mutually perpendicular axes.
(3) Add vectors in order to find the net displacement of a particle that undergoes successive straight-line displacements.
(4) Subtract displacement vectors in order to find the location of one particle relative to another, or calculate the average velocity of a particle.
(5) Add or subtract velocity vectors in order to calculate the velocity change or average acceleration of a particle, or the velocity of one particle relative to another.
b. Students should understand the general motion of a particle in two dimensions so that, given functions x(t) and y(t) which describe this motion, they can determine the components, magnitude, and direction of the particle’s velocity and acceleration as functions of time.
c. Students should understand the motion of projectiles in a uniform gravitational field so they can:
(1) Write down expressions for the horizontal and vertical components of velocity and position as functions of time, and sketch or identify graphs of these components.
(2) Use these expressions in analyzing the motion of a projectile that is projected above level ground with a specified initial velocity.
d. Students should understand the uniform circular motion of a particle so they can:
(1) Relate the radius of the circle and the speed or rate of revolution of the particle to the magnitude of the centripetal acceleration.
(2) Describe the direction of the particle’s velocity and acceleration at any instant during the motion.
(3) Determine the components of the velocity and acceleration vectors at any instant, and sketch or identify graphs of these quantities.

Making a Quest Homework Account
Please go to this link and start an online homework account. Click on "get started" and then choose "I need a UT EID". If you had an ID code last year, it should continue to work. In the next window choose "get a UT EID". 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 Wednesday 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 223 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 Phys (Grant High school 2011 Fall). It will probably be one of the last ones. 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 assignent" windows to start the Kinematics homework.

Welcome Back and General Information
The 2011-2012 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. 20.) 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
