students return from extended faculty have countless meetings |
|
|
|
|
| what
we'll do in class |
center of mass and its connection to conservation of momentum |
find out what "work" really means |
the work-energy theorem |
more
applications of othe work-energy theorem in addition to doing lab A11 |

make sure you are wearing lab clothes when you come to do the collision before coming to lab, read the first page of the lab carefully and make sure you follow the 10 guidelines in number 5 of the Procedure you do NOT do any of the Results/Analysis until lab day Friday (bring your spark sheet friday!) |

solving on gravity and circular motion |
connect
to the lab that we did last Friday |
test
on chapters 5, 6, 12 |

|
(always done before class) |
know Kepler's 1st and 2nd laws |
(yes, we know you don't know what kinetic energy means yet) |
|
[notice that we did section 9(2) in class yesterday?] make sure that you know the lesson(s) of the hail and the rain for class today! |

homework (by 5 pm) |
& 12(29, except I suggest that you do part b first) |
|
clothes are being dried in a circular clothes dryer which spins the clothes in a vertical circle or radius 0.70 meters.... find the rotation frequency (in rotations per second) such that the clothes are NOT in contact with the dryer wall when the angle that the dryer wall makes with the horizontal is 75 degrees |

one of your practice problem
solutions can go up on the bulletin board in the hallway (take care not to put up a duplicate of one already there) |

we'll do in class |
lab
quiz |
we
start gravity! mg is NO LONGER down! |
lab
A10 there is a very short pre-lab, but also put the data table in your lab book spread across two facing pages |
||
|
(always done before class) |
(the last of chapter 6) |
|
also bring to class a list of the main features of the gravity law, including a) what property of an object produces a gravity field? (we call this the "charge" of the object) b) what objects participate in ("feel") the gravity force c) what's the direction? d) what does the magnitude of the gravity force (between 2 "charges" depend on)? |
know how to calculate the gravitational field strength g and what it depends on also review the examples that involve calculating the gravity force with the new law |
on Kepler's third law and the example of sun/mercury |
| in-class
presentation |
6(51) |
6(46) |
look
at problem 12(7).... but INSTEAD of doing it, find the ratio of the gravitational force between earth and moon to the gravitational force between sun and moon |
6(86) |
|
|
homework (by 5 pm) |
(hopefully you know why) |
|
|
|
and yes, 12(14) still requires a force diagram, and a net force equation (I've removed 6(81) since I forgot that you have to prepare for lab) |
|
|
|
(A5, A6, A7AD, A8c completed) due after class today |
|
|
lab A10 data |
|
|
|
if your
variable was Fnet in lab A6, make sure that you put your system mass up
on your presentation |

both done in GREEN book part of tomorrow's lab will be outside; the temperature will be in the mid-50s; therefore no shorts; long-sleeve shirts or jacket/sweater required |
|
| what
we'll do in class |
lab
A7 part D + a walk-around quiz |
circular
motion: pp. 162-165 |
more
about circular motion bring some (written) examples of circular motion with you to class |
more circular motion; today we do vertical circles |
lab on horizontal circles (a human merry-go-round) and a lab on vertical circles (the swings) |
|
(always done before class) |
6-4 (page 151), 6-5 (page 156), active example 6-3 (page 157), example 6-7 (page 161) |
KNOW how they (the text book authors) derived those 2 things read the force diagram handout (on BLUE card stock) |

|
| what
we'll do in class |
lab A8c: the acceleration of elevators |
inclined
planes! |
talk
about kinetic friction |
lab A7,
part A talk about static friction |
|
|
(always done before class) |
|
and example5-9, page 131 also read about inclined planes in TWTW |
|
6(1) up to where static friction begins: know the magnitude and direction of kinetic friction know what the kinetic friction force doesnt depend on |
know the direction of static friction and what the formula is for the magnitude of static friction |

|
|
5(33) |
|
lab A7, part A ONLY done in lab book 6(37), the problem we started in class on wednesday |
|
|
|
(and in your lab book): include 1) data table of ordered pairs 2) linearized graph with linear fit 3) 5 column matching table (the last two columns of the matching table are expected value of the fit parameters (slope & intercept) & % difference between actual fit parameters and expected fit parameters 4) conclusion 5) statement/signature by all participants that work was shared equally |
