Due to a medical emergency I must cancel lecture for today, Tuesday! Big disaster.I will set up a special circular-motion study-reading homework assignment for bonus points, to replace some lecture work. Look for that this afternoon.
See you for more some good gravitational acceleration concepts on Thursday, normal time. That will be wrap up of chapter 4 and digging deep in chapter 5, universal gravitation.
Hopefully the doctor will not have to amputate at the neck. :)
However, be aware: it will not always be so rapid!
Bonus points:
Exam1's highest score was 49/50 and lowest was 26/50, so nobody aced it, yet nobody flunked it either! This tells me the exam was challenging yet fair.
There are a few students who were absent or who have a score pending for some other reason. For those students, the My Grades page reads either "pending" or "no score reported." We will try to sort that out when I get back to campus next Tuesday.
If you go into Webcourses and check the Lecture Files, then you will see a little blurb page of Exercise 11, p. 73, the baseball exercise we worked out in lecture yesterday. I added some extra detail and a nice color diagram with velocity vectors accurately drawn. Have a look and see if it makes sense to you.
Go get after the eight exercises in HW 6. It is now available inside Webcourses.Prepare for exam 1. Office hours tomorrow morning 8:00-9:45 AM and 2:45-4:15 PM, in Starbucks, UCF bookstore.
Also, I posted the lecture 6 CPS scores, designated L6. Also, the Gaby Guide PDF is available in the Napoleon Dynamite section.
There is a page in The Lecture Files with the four questions I asked in lecture on Tuesday, Jan. 22.
Our next homework assignment is now ready. HW 4 also has a brain burner that requires some nifty moves with the drop distance formula.
Look for the new file area on the home page, with the Napoleon Dynamite icon. This is where the Gaby Guides will be after each lecture.The Gaby Guide is just the streamlined "study guide" that I get CPS to produce in PDF for Gaby's work. It shows each question, each of Gaby's answers, and the correct answer. Works pretty well. It is a good study guide when reviewing CPS questions in case you did not jot down each question in lecture. Also, they are quite nice when preparing for a midterm exam!
Look in your My Grades page. The scores for today's CPS session are now UP inside Webcourses. Every lecture we will have two sets of data like this, e.g.,| L5 correct | 7 |
|---|---|
| L5 answered | 8 |
We will have varying numbers of questions in CPS, usually a handful, sometimes more than that. At the end of the semester, if I have asked 120 CPS questions and you have answered 102 of them, that is 85% answered. Therefore you will get all 20 points in the CPS part of your semester grade, as explained in the syllabus. If, however, you only answered 81 out of 120, that would be 67.5% answered, and you would get proportionally fewer points on your semester grade; in this case, the number of points, n, is 15.88, which I would round up to 16 points for simplicity.
The "number correct" score for each session, starting with L5, will tally up this way for you at the end of the semester.
