An outline of topics to be addressed each day is presented below. This list is not complete; additional items are covered for most classes. If students are absent, they should consult these pages and check with the instructor concerning material missed.
¢ Last Month
¢ If you do an exercise before it is assigned (date placed in Assigned) then it is at your own risk. Many times I change the assignment up until
it is actually assigned.
¢ Schedule: Check periodically, I do not provide daily, by page, etc, reading assignments - check the schedule and stay up with reading IAW
the schedule and my presentations
¢ Chapter 3: Kinematics in Two-Dimensions - Vectors
¢ Lab 3
¢ This is an AP course: See my philosophy and policies (perhaps read it again)
¢ If you cannot hear, then raise your hand (or move closer to the front, or both) and I will address it
In 12 years, this is the first time anyone has had such a problem.
¢ You may want to consider bringing the text to class each day - I will not state when you should. If I give time to work on assignments, you may
find the text useful.
¢ Chapter 3: Kinematics in Two-Dimensions - Vectors Utilization in one of my Computer Science courses
¢ First lab tomorrow, review exercise Friday.
¢ Exam Prep: report here, we may go to another room in groups
Ø Picture and outline of first lab.
Ø Lab requirements and procedures
Ø Each student provided a copy of the lab exercise
Ø Break into groups of 3 students each to perform the lab - each student keep a copy of the observations
Ø Need to turn in only 1 lab sheet per group
Ø If all copies of the data from the lab are lost then each member receives the appropriate grade
Ø Lab 1-1
Ø Movie: Galileo's Battle for the Heavens (final section only - relates to lab tomorrow)
¢ If I finish early, you can work on lab assignments, study for the Review Exercise, or read the material in preparation for the lab tomorrow
Thursday (Double Period)
¢ Lab - meet in room 212
¢ Review Exercise next class
¢ Addition to Student Quotations page
¢ Organize into 6 teams of 3 each and turn in 1 report per team in accordance with the stated instructions
¢ I will accompany 1 teams at a time to the lab downstairs - remainder can prepare for lab, work on exercises, or study for review exercise.
¢ Some plotting examples
Ø Equation for straight line: y = mx + b where m is the slope of the line (delta y over delta x) and b is the y intercept
Ø Plot of x = t2 (t along the horizontal axis) is a parabola
Ø Plot of x = z (z along horizontal axis) where z = t2 is a straight line
Ø Plot of x = (1/2)at2 where x is measured along vertical axis and t2 is measured along horizontal axis (t2 along axis, not t)
] Is a straight line if a is constant
] If a is constant, then the slope is (1/2)a
¢ Change to lab instructions: Plot the data using the graphics program
¢ Review Exercise on material in chapters 1 and 2
Procedure to be followed for students that do not bring a writing instrument to future review exercises
Read cover material
Do not turn page until told to do so and you have read the cover material
If a student is absent, that student will receive a different review exercise
¢ Exercise and Lab assignments are now on separate pages. They will be referred to as Exercises and Labs.
] Follow the numbering scheme when submitting assignments
] Labs

] Fill in the blanks: 2
] Calculations (or show logic): 3
] Extra Credit: 1/2
] Cutoff (stopped grades there): 80
¢ Review Exercise Comments
] For all future Review Exercises and Exercises where appropriate, show the following at the beginning of the problem. I will have a place on the exercise
specifically for the components listed below
A diagram or sketch of the problem clearly indicating the positive direction
The equation or equations that you are using - place a box around them
The variables you know and what their values are
The variable you are solving for
] If you have a reasonable idea about the answer, then that is better than leaving it blank
] Do not guess and place frivolous answers - I may deduct points
] Follow instructions and be careful if you make any assumptions
¢ Exercise 1 graded and returned Exercise Solution 3 points each
Note: If you have a question about grading, check the solution and then see me about it next class period
This approach is to prevent wasting time with "knee jerk" reactions
¢ Exercise 2 was due 9-2: Division policy is 4 points per day late. Note the end date - not accepted after that date
¢ Chapter 3: Two-Dimensional Kinematics
¢ Take a picture of team 6 by the setup downstairs

] Name, Date, Lab number (my designation, not yours)
] Points are being deducted
¢ Lab 2: Many students - as previously observed by other faculty - cannot read graphs
] Follow instructions - I did not state you had to copy and submitit the graphs - just the answers!
] I stated you must show work. If you do not, the answer is counted as wrong regardless
] Everyone missed problem 7: travel to B and then to C...
] Grades ranged from 60 (3 received) to 95 (2 students received)
Friday (Double Period)
¢ General Commentary to avoid future problems
] This has has been a good class
] Approach to follow if you ever have a question about a topic or the way a paper was graded, or need extra help before or after class, etc.
] Knee jerk reactions discussion and how I avoid them - that was covered previously and, apparently, not understood by at least 1 student
] Showing a lack of respect for anyone will not be tolerated
] Talking or otherwise not paying attention in class. A Show Time Exercise will always be available - starting today
¢ I will explain the next exercise in any appropriate detail needed next class
¢ This class, work on the lab exercise only - downstairs or preparing report
¢ Target Practice: Trajectories: Follow Instructions
] Part of the class will be in the classroom working on the written portion of the lab
] Part of the class will be downstairs working on the lab assignment
¢ Do not rearrange current placement of desks - it is done to ensure that everyone can see and hear.
¢ Assignment given earlier returned for 5 teams (they submitted solutions on 9-16 and 9-17) grade was assigned - 100 - good work
Team that did not submit (team 4) has until 3:30 today
¢ Check status of assignments and submissions frequently - my notebook is always on the desk at the front.
¢ Target Practice: Trajectories:
Note: In order to make up some time I have eliminated the second part of the lab. Use the trajectory equations for the first part
] There are some interesting manipulations involved, however, and I will summarize them in class and point out how they differ from the relatively simple
problem solved in your text: example 3-8 on page 360
¢ Exercise 4: Note the suggestions and hints provided for each problem
¢ Exercise 3 solution and discussion
¢ Some additional example problems illustrating material in chapter 4: on the board only - not on my site
] Box on an incline with friction
] Walking on a rope
] Pellet gun

] Box on an incline with friction
] Walking on a rope
] Pellet gun: acceleration to attain given velocity
] Fish on a line that breaks
] 2 pulleys and 2 objects

] 2 Additional Problems with Solutions Sample Problems with Solutions
¢ 10-12 not in class
¢ Double class lab day: Tuesday of next week: note the format for all lab reports
¢ Donuts exercise (donut alternatives in the future)
¢ Exercise 1-3
Note: The solutions have been posted for a number of days - if you have questions about why you missed a problem - in accordance with my policy (encouraging you to review the solution first) then see me next class.
] Name, date, exercise (or lab) number at top of first page - points will be deducted in future
] Read the problem - do no make assumptions that violate what is given (if stated that vectors are positive, then they are positive)
] Instructions are to give reasons for logic problems - some did not
] Vectors have components, whether they are vectors, a, b, c, etc. or the resultant of the vectors a, b, and c (found, by combining the components of
vectors a, b, and c) (see page 49 of the text) components are along the x and y axes in 2-D
] If a question is yes or no, then begin by stating yes or no, followed by rationale
] Place answers to questions in sequence - to do otherwise is just trying to make it harder for the instructor ot find it - or easier to make an error...
2 students had answer pages out of order
] Very lenient on last 2 problems - looking for correct approach
] 15 questions, counted 3 each, 65 was lowest grade possible unless points deducted for not providing rationale for logic questions as instructed earlier
] On cover of all assignments I place the number missed times points per problem to give points lost and then subtract that from 100.
Your grade is the number circled
] Grades ranged from 62 to 100
¢ Exercise 1-4
] 12 problems - counted 3 each
] Grades ranged from 90 to 100
¢ Check my notebook frequently - grades and assignments submitted are always there
] Fill in the blanks and definitions
] True False
] Problems and Analysis
] Extra Credit
¢ Topics from Chapter 5
] Centrigufal force on clothes in a dryer
] Acceleration of a car around a sharp versus a less sharp (larger radius) curve at same velocity
] Forces on a child on a merry go round
] Why water in a spinning bucket does not fall out
] Why airplanes bank in turning
