bring 3 examples of circular motion in your notes to class (e.g., a piece of gum stuck to the rim of a rotating bicycle wheel) |
can you think
of example of circular motion where the force toward the center of the
circle is kinetic friction? we might do lab, so wear appropriate stuff |
|
|
|
(always done before class) |
|
know the magnitude and direction of acceleration when traveling in a circle also, finish up reading in chapters 5,6: section 5(7); examples 6-2,3 |
example 6-9 is the important example also, we still have to talk about the magnitude of circular motion acceleration (and the derivation the book did to get it) |
(page 162) |
(p. 159-160) + the two paragraphs after the example |

newton's law lab |
|
friction labs (A7, parts A and D) completed and handed in walk-around quiz shown to me, if you didnt finish in class on monday; that problem [6(35)] was a good test of your status as a problem solver of inclined plane or force triangle problems; you want to be able to do a problem of this type in 15 minutes or less |

C/D:class
does lab A7 part a & learns about static friction F: only gets to learn static friction all classes do 6(11) in class |
|
|
|
(always done before class) |
& example 5(9) (bottom of p.128 - 130) you will actually use these two tomorrow, but I dont want tomorrow's reading to be too heavy |
6(1 up through the top of p. 141): know the magnitude (formula) and direction of the kinetic friction force; you will be quizzed on it |

homework (by 5 pm) |
post your group's poster presentation for lab A6: includes 1) ordered pairs & the value of the independent variable that remained constant; 2) graph with linear fit; 3) 5-column matching table; 4) conclusion 5) equal-sharing statement (that partner shared in the work) + signatures the above stuff (except for #5) should also be in your individual lab notebook card stock for the posters available in/near the black boxes |
|
& 5(25) be careful on 25: which way do you define + and break up forces (look at example 5-9!!) |
|
6(1), 6(27) is one of these an inequality? (hopefully at least one of these youll do before you leave!) |

homework (by 5 pm) |
remember to refer to the 7-step procedure in your notes (both for the Fnet problem and also for the requisite dvat problem) question 5(13); this question has 2 parts: 1) why is the horse's logic faulty? (why isnt the net force on the cart = 0) 2) assuming that the horse/cart actually do accelerate, what force actually DOES accelerate the cart forward? what force accelerates the horse forward? |
|
& question 5(8); once again. explicity mention which of Newton's laws you are using in your explanations |
|
