## Office Hours (Updated for FINALS 2007)

### You can look up your Final Grades here.

### HW -- 1/09 Tu -- Read Ch.1-2. Ch. 1 problems: 2,3 (on
own), 6, 10 (will be turned in for 1/16 Tu)

### HW -- 1/16 Tu -- Think about your model of light; Ch. 1 problems
3, 5 (to be turned in for 1/18 Th); Quick Quiz on
1/18 Th

### HW -- 1/18 Th -- Section 1-5 on Interviewing about what "a few
people" think about light (to be turned in for 1/25
Th); Test Case 3 on p. 16 -- write up for your portfolio. Don't forget
class and first test in 1110 Rood Hall on 1/22 Monday!

### HW -- 1/23 Tu -- Chapter 3, problem 3 (to be turned
in for 1/25 Th); Think about Ch. 3 problems: 1,2,4-9,12 (on own),

### HW -- 1/25 Th -- First, hold off on turning in stuff for 1/25 Th until 1/30
Tu, Dr. Phil needs to catch up on sinuses, sleep and grading; Second, we should
be having a Quick Quiz in 1110 Rood Hall on 1/29 Monday -- I'd be thinking
about similar triangles and shadows; Third, come up with a method of measuring
the height of the light pole visible out the lab's window -- if you and a
partner were out there on a sunny day (in Michigan!!), how many times your
height is the light pole?; On Own -- look over Ch. 5 problems.

### HW -- 1/30 Tu -- Chapter 5, problems 5 and 7 (pages
84-85?) add 26? (pages 94-95) (to be turned in
~~2/1 Th~~ 2/6 Tu);

### HW -- 2/6 Tu -- On your own for your notes,
Chapter 5-9 D, the edges of the shadow from the sun (pgs. 80-81);
think about how the V-filament through the pinhole
works; if you missed class today, you will need to make up Test 2.

### HW -- 2/8 Th -- Chapter 6, problems 9 and 10 (pages
118-119) (to be turned in ~~2/13 Tu~~ turn
in after nice sunny day so you can do problem 9);

### 2/13 Tu -- REMINDER: Finish your Reflections on Test 1 if you're going to
do them. Will collect through class on MONDAY
2/19.

### HW -- 2/15 Th -- Chapter 9, problems 8 and 11 (pages
180-182) (to be turned in 2/20 Tu);

### HW -- 2/20 Tu -- On your own, Chapter 9,
problem 13 on who you can see at the dinner table.
(Sigh, people simply did not do this and we had to take
class time.) REMINDER: Monday 2/26 will be the
last day to turn in: (1) the HW with measuring the Sun and (2)
Reflections on Test 2.

### 2/22 Th -- Monday 2/26 will be Quick Quiz 4 -- if you brought a protractor
with you, you'd be able to draw straight lines and similar angles.

### 2/27 Tu -- HW Chapter 10, problem 2 (pages 206-7?)
(to be turned in ~~3/1 Th~~ 3/12
Th);

### 3/1 Th -- HW Chapter 10, problem 5 (triangle problem,
page 210?) (to be turned in 3/13 Tu);

### I don't know about you, but I'm tired. Call in sick
next week (March 5-9) and don't show up for class.

### REMINDER: Mid-Term Monday 3/12 in 1110 Rood Hall after Spring Break. Does
NOT include Refraction.

### 3/12 M -- The Mechanics Coursepack for PHYS-1800 goes on sale TUESDAY 13
March 2007 at 9am. It will cost $34. You should make every attempt to have it
for ~~Tuesday's~~ Thursday 10am lab class.

### 3/13 Tu -- If you didn't finish the two columns (1 and 2) on the last page
of the handout/Mechanics Coursepack (pgs. 15-16),
do so at home.

### 3/15 Th -- HW pages 32, 33 (1,2) (we haven't done
acceleration yet, you can do the "a" part for extra credit) (due 3/20
Tu). We probably have a Quick Quiz on Monday, imagine it has something
to do with motion maps, maybe intervals...

### 3/20 Tu -- HW pages 34, 35 (3,4,5) (uses information
from previous HW) (due 3/22 Th).

### 3/22 Th -- Reminder that you should go over the procedures for making an
s,v,a motion map, and going through the __multiple__ steps required
to from position (s) and time (t) to calculate acceleration (a). Why? Because
we're probably going to have Test 4 on Monday. HW 7 (p.
50) (due 3/27 Tu).

### 3/27 Tu -- Do page 59 for Thursday with the following question: "A car speeds up from 3 meters/second to 9 meters per second
with an acceleration of 2 meters/second/second. How much time does this
take?"

### 3/29 Th -- Quick Quiz on Monday, I strongly urge you to review both using
algebra/calculations and word-logic to work out problems. HW
5 (p. 70 - read the directions CAREFULLY), 8 (p.71) (due
4/3 Tu).

### 4/3 Tu -- HW (p. 42, fan problems) (due 4/5
Th). Portfolios -- Dr. Phil will collect on
~~4/12 Th~~ 4/15 Tu, return on 4/17 Th.

### 4/5 Th -- No new HW. Test on Monday will cover some of the things on motion
calculations not previously tested in the last test, fan and strobe, and some
of our thoughts on the concepts of force.

### 4/10 Tu -- No new HW. But ponder the questions on
page 128 -- will discuss on Thursday's class. Upcoming events as the
semester winds down: Quick Quiz on Monday, Review of Refraction a week from
Thursday on 19 April 2007, Final Exam a week from Monday, 23 April 2007 from
10:15 am to 12:15 pm in 1110 Rood Hall.

### 4/12 Th -- No new HW. Want Test 5 Reflections
on Tuesday -- will give back on Thursday. Collecting Portfolios, for those of
you who wish to turn one in, on Tuesday -- will give back on Thursday. Quick
Quiz on Monday -- probably covers Forces, Newton's First Law, balanced forces
(no net force), unbalanced forces (net force), acceleration in same direction
as net force, etc.

FYI: If allowed to drop from rest, then a real object may not free fall
continuously, but may reach Terminal Velocity. (Force of gravity down canceled
by Drag force up) and doesn't accelerate any more. Ping-pong balls versus
turkeys or pennies.
World's
Record Free-Fall.

### 4/16 M -- No, you weren't dreaming. QQ7 won't be graded, you get all the
points. Well done! Oh, and thanks to our charming Little Red Wagon Physics
Force Demonstration Team!

### 4/17 Tu -- Portfolios collected, will evaluate on Wednesday and return on
Thursday. Last test reflections collected. Last class on Thursday!

### 4/18 W -- FYI: Portfolio grading completed.

### 4/19 Th -- Review topics for Final Exam: Refraction, Kinematics and
Dynamics. Return portfolios and Test Reflections for Tests 4 & 5. *Prof. Schuster recommends you bring the following to the Final
Exam: pen/pencils, ruler, protractor, compass (kind that draws circles, not
kind which points North -- grin).*

## See you Monday!
