extended weekend

only faculty have classes
 
we're doing lab;
see lab slot below
 
 test on 2-dimensional motion


what we'll do
in class

finish up the hanging-bottles-
in-front-of-the-class demo

talk about push scales

we do lab A6

see below


reading
(always done
before class)
 
if you have time after you're back:
5(7) just the first page
(mid p 128 - mid p 129)
 
 
 
in-class
presentation


prelab to lab A6
(this should take fewer than 10 minutes.... you dont have to do the full-blown 7-step procedure, but you do have to use one of Newton's laws)


question 5(8),
p 134

written
homework
(by 5 pm)

 
question 5(11),
p. 134

this question has 2 parts  -- make sure that you answer both:
1) why is the horse's logic faulty?
(why isnt the net force on the cart = 0?)

2) assume that the horse/cart actually do accelerate; what force (by whom? on whom?) actually DOES accelerate the cart forward?  what force accelerates the horse forward?
problem 6(27, part A ONLY)

this is the first problem where we use the 7-step procedure

make sure that you have studied conceptual checkpoint 6-3
(pp. 155-156)

please have your notes (containing the procedure ) out while you are doing this problem
 
lab
 
did you finish up lab A5 by writing a conclusion? 
lab A6

done in the  RED book (the only one you have)

make sure you come with the lab book prepared, the data table spread over 2 pages in your lab book, and have read the lab, so that you know the two experiments being done (although you will only do 1 of the 2)

projectile problem A1 only

use this applet to test your answer

Question (not problem!)

use Newton's laws explicitly as explanations for your answer!
written
homework
(by 5 pm)

prelab done in the
A4 lab book
and turned into black box
 

1) projectile
problem C
(you should have at least 3 conclusions from your data table)

use this applet to collect data, but do NOT follow the instructions for problem C in the applet, but use the link at the very top of this box

the second one is tougher; don't wait until tuesday night to start it!

2) projectile problem D
 
 questions (not problems!)
5(10, 12) on page 134

be sure to use N's laws explicity as part of your explanation!
lab
it would be nice to have your 5 graphs printed and entered on the left pages of your lab book with the matching tables done on the right 
bring all 5
lab A4 graphs  to class
(I will bring your
A4 lab book)
 
 
 we do lab A5 lab A5 in the RED book

lab A4 is due

did you finish the problem we ran out of time on at the end of class last friday?

are you keeping track of scores on returned assignments?? 
see recent email

shoot the monkey

 print a copy of the course expectations to take home to your parents this weekend so they can begin studying for the parents' day quiz

oh, and have you measured the length of your family's car hood, to make sure that you dont own a deathtrap
 
make sure your 4 % differences are less than 5% or else you cant hand the lab in

do our 2nd  d-v-a-t problem, which will be a lot more challenging than the first one!
learn how to interpret linear and quadratic fits and do matching tables,
a technique that we will follow for every graph from now on!
reading

velocity-vs-time graph completed and brought to class
(pink sheet);
don't forget to show work
1) calculate the displacement of the dropped object after 50 seconds

2) bring to class today a new table for a "thrown" object (an object whose initial velocity is 20 m/s)
(see email)


prepare lab notebook for lab A

spread the data table across two facing pages of your lab notebook
(if you've already done it on one page, that's ok)

1) bring a printed graph of your position-vs-time data (from yesterday's lab) to class today:

a) Label your axes with the quantities being plotted
(followed by units in parentheses)

b) do a QUADRATIC fit to the data and make sure that the quadratic fit values (ABC) are showing on the graph when you print it

(note that the standards for graphs are on the second page of your lab guide that is taped into your books)

I would strongly suggest using the Graphical Analysis (juniors, perhaps your senior partner will show you how?)


2) acceleration-vs-time graph for the pink sheet

 bring a printed graph of your velocity-vs-time data (from wednesday's lab) to class today:

a) Again, label axes with the quantities being plotted (followed by units in parentheses)

b) do a LINEAR fit to your data and make sure that the slope and intercept values are showing on the graph
when you print it
