block G:
pp. 152-153 (on springs and Hooke's law),
p. 405...
"x" means "displacement from the unstretched length" in all these sections
 

block A:
pp. 152-153 (on springs and Hooke's law),
p. 405... remember that the book's
"x" really means  "delta x" = "displacement from the unstretched length" in all these sections

block G:
13(2) and
read over part B of the lab so that you know what you are expected to do

block A:
13(2) and
read over section II  of the lab so that you know what you are expected to do

both groups:
know how to write the general equation for simple harmonic motion, and know how to solve for each of the 4 constants in that equation
[I am relying on your knowledge from precal here, although everything is contained in Walker 13(2)]

(by 5 pm)
challenges 1 and 2;
follow the usual force diagram procedure (Walker does a similar problem on pp. 722-723, but he does not do very well at following OUR established procedure -- get out those guides to force-diagram problems! --  I'm sure you will do much better)

for challenge 1 and some of the later challenges, you will need to have access to the Charged Particle software because it shows you time, tells you if your solution is correct, allows you to make measurements, etc.
(you can do most of challenge 1, however, without the software, and I encourage you to do so)

block G, you'll need to be extra-prepared to finish lab, because it MUST be done in one sitting
 test in block A

test covers anything related to circuits and includes building and measuring;
this means it includes (this may not be an exhaustive list):
labs D3, D4, D6, D7; the half-test and the ohms-law quizlet; chapters 21 and the parts of chapter 20 related to circuits, 26(1) on ac voltage and current
both blocks
do lab D9
 block A does lab D9

class





bring BOTH lab books to class!

lab practical half-test
(see below) for
both classes
it will go in RED lab book;
remember to bring it! .... you will not be able to start the test without it

block A will also start lab D6 in GREEN book in the first half of the lab period and have the lab test in the 2nd half of the block





what we'll do
in class



we will put the 25W and 100W light bulbs in parallel in a circuit and see how they behave
(as opposed to putting them in series as we did last thursday)

and if there is time, start/continue

lab D6




lab practical half test on circuit measurements and calculations; bring RED book!
material covered:
labs up to and including D4;
reading up to and including 21(3)

you will be able to use your textbook, lab book, circuit guide, and notes and green handout (see below); however the test will be timed and if you have to look up or re-read things, you will not finish very much
start
lab D7

it goes in the same book as D6 (GREEN); same partners as D6

(assuming that you have finished lab D6 and gotten all checks)


work on D7


work on D7


reading
(always done
before class)

block G: the part of 21(4) on resistors in parallel

block A: the part of 21(4) on resistors in series


GREEN handout on resistivity

block A: the part of 21(4) on resistors in parallel


24(1) sometime this week on duke voltage difference and why it is 120 volts

because you are
working outside of class
on labs

(by 5 pm)

20(19 a and b)

in addition,
you and your partner need to spend 3 - 4 hours outside of class this week, working on labs D6 and D7

they need to be finished by friday!

D7 could take 4 - 6 hours

do not wait till the end of the week; trust me, there will be a multimeter shortage!

if you are working outside of class and need a multimeter, you will need to ask a teacher for one, and return it to a teacher's hands!





lab

(no topics class is taught during blocks D or E
this trimester)



advice for D7:

follow directions  on handout!

as soon as you have written down the loop rules, the junction rules, and ohm's law for each resistor,
get those equations initialed by one of the work service students

that should be all you need to calculate the currents through and voltage differences across each resistor

after you do each measurement (matching calc just mentioned), get another initial and move on to the next circuit

ALSO
IMPORTANT:
get one of the work service students to teach you how to use an extra bare wire to measure a current when you have a parallel branch in your circuit

block G starts lab D6 in the GREEN book (new lab partners that you havent had yet this trimester)


what we'll do
in class

lab D4 continues in RED book




integrate what we learned in Ohm's law lab (D4) with textbook reading

a quizlet on lab D4 (and to some extent labs D2 and D3) and the associated reading
(although this quizlet is important in that it takes stock of your knowledge about circuits, it will count less than 1% of this trimester's grade

 21(2) if possible;
if not, it cant wait till thursday

lab

(no topics class is taught during blocks D or E
this trimester)

 hopefully you have plotted your data collected for part B before the break
and had it graded before break

if not, it would be nice to plot it and construct the matching table before class today
bring plots of the Ohm's law data (lab D4)  along with the corresponding matching tables in RED book
(separate plot/table for part B data and  for part C data)

guidelines for perfect graphs are in the back of your lab book; please read!

guidelines for matching tables are partly there; these are 5-column matching tables:
math variable, physics variable, slope/intercept from graph; expected slope/intercept (from measurements);
% difference where appropriate
