Jan 19 - TEST - Dynamics (Chapter 4)
Dec 18 - TEST - Chapter 3.1 to 3.3 - Projectiles in 2-D
Assignment: Read - Chapter 8.1 to 8.3. Mark summary notes. Pay specific attention to highlighting the ways in which rotational motion is analogous to linear motion. Do 9th Edition Page 233/234 "Focus on Concepts" #1 to 7 (from the handout)
Dec 8 - QUIZ - Projectiles in 2-D (refer to worksheets; Chapter 3.1 to 3.3)
NOTE TO ALMOST 100% OF YOU re: the "Graphing Free Fall" activity. All graphs must have descriptive titles describing the specific situation they depict. Read the assignment sheet carefully. The situation does not describe 4 generic projectiles. A ball is thrown off a roof. That's a specific projectile (a ball, rather than another type of object; and thrown off a roof, rather some other random location). So, the title of the graph should be: "Position vs Time Graph for a Ball Thrown Off a Roof" (not, " ... 4 projectiles". You know exactly what type of projectile, so, you must state the specifics rather than leaving it vaguely stated as a generic projectile)
NOV 30 - in class - Optional ReTest of Chapter 2 Test - Can be done in Sections (only re-test the question(s) you struggled with on the first test).
* in general, the most weakly done question on the test was Section A (graphing) question #4 - analysis of v vs t graph. Specifically, many people struggled with determining displacement by calculating the area under the velocity vs time graph, and determining the equation of the line in the form y = mx + b.
- Note: "area under the curve/graph" refers to the area between the line/curve and the x axis. So, when the line is above the x axis, calculate the area "under", but when the line is below the x axis, the area is "above" the line - between the axis and the line. e.g. as the term is used in math (calculus): http://www.mathwords.com/a/area_under_a_curve.htm
* the second most weakly done question was Part B #1, determining average speed and velocity when the 2 parts of the trip take different amounts of time
- it is important to note that in this case (the two parts of the trip taking different amounts of time), "average speed/velocity" is NOT (v1 + v2)/2.
- Rather, average speed = (total distance)/(total time)
- And, average velocity = (total displacement)/(total time)
The retest sections/options will be:
Part A - Graphing:
- questions 1 and 2 (interpreting graph sketches)
- question 3 (position vs time graph and instantaneous velocity)
- question 4 (position vs time graph)
- question 5 (velocity vs time graph)
Part B - Kinematics in 1-D
- question 1 (movement with multiple sections at different constant speeds: non-constant acceleration throughout the trip)
- question 2 (horizontal constant acceleration)
- question 3 (vertical constant acceleration/free fall/dropped)
- question 4 (free fall, initial velocity not equal to zero)
FRIDAY NOV 24: LAST DAY TO SUBMIT ASSIGNMENTS TO BE INCLUDED IN THE FIRST REPORT CARD MARK
- the Nov 28 re-test will be included in the first report card mark
- the FORMAL LAB (pendulum lab) will be included in the SECOND report card mark (there won't be time for your revisions, and for me to mark them, before the first report card deadline). You must submit your final version of the Formal Lab by December break (Dec 22 at the absolute latest). MsB will mark the final labs over Xmas break.
NOTE: When submitting corrections for your marked Pendulum Lab, you MUST include the previous draft of your lab (marked) and the marks sheet -
Refer the following 2 files for some suggestions (Sources of error, conclusion, and discussion sections)
Optional Retest: Nov 28 - Graphical Method (Chapters 1 and 3.4)
Optional Retest: Nov 21 - Goal Day - Analytical Method (Chapters 1 and 3.4)
- 9am to 10:30am (with the physics 12 block 5 class)
Nov 17 - TEST - Kinematics in 1-D (Chapter 2 style and level of questions)
- NOTE: This test includes interpreting d vs t, v vs t, and a vs t graphs
HAND IN (if you haven't already):
- Force Lab
- Sally the Spider
- Chapter 2 assignment
Do (hand in on Wed Nov 1) - Textbook Page 49 # 1 to 3, 5, 7, 8, 81, 82 (note: #81/82 include 2 parts - concept and problem)
TUES NOV 7 - TEST - Analytical (mathematical) Methods of working with vectors in 2-D
NOTE: Please read the "Pendulum Lab Revision Advice Marks Sheet document posted below! I have started assessing the drafts and have already noticed a number of common errors. ALL students should read the advice and check your labs to see if you need to make changes to those sections. I will return the labs on Monday for you to revise. I did not have time over the weekend to read in detail the long written sections (Theory, Procedures, Sources of Error, Conclusion, Discussion) - But, almost everyone has to do corrections in the other sections, which may then lead you to want to change or further develop the long written sections. So, start with the corrections to Title, Purpose, Data Tables, Graphs, and Calculations and Data Analysis, then try to refine the rest, and resubmit for further assessment. SUBMIT YOUR REVISIONS BY OCT 26 AT THE LATEST.
Tues Oct 24 - TEST - Graphical (scale diagrams) Methods of working with vectors in 2-D -- Calculators are NOT permitted for this test. You may use ruler/protractor/geometry set.
BOTH TESTS relate to Chapter 1, 3.4, and the sections on chapter 4 that involve static equilibrium (net force = zero, therefore acceleration = zero)
For Oct 16 - do as much of the following as possible:
Page 20 - Questions #8 to 10, 12 to 19: Problems 12, 14, 16, 21, 22, 30
Vectors in 2-D activity (height of the classroom ceiling) - For concepts/reference, refer to the following sections in the textbook: Chapter 1.5, 2.1, and 2.2 (scalars vs vectors, distance vs displacement, speed vs velocity)
Thurs Oct 12 - Optional Re-Quiz - Graphing (same format as the Sept 25 quiz) [in class]
Tues Oct 10 - Formal Lab Report Due (Pendulum Lab)
** Complete the lab write-up as completely and effectively as you can (refer to "Writing Formal Lab Reports" handout for guidance). Since this is your first formal lab, if the teacher notices deficiencies when assessing the lab, you will be given additional time to revise your work (in other words, do your best to submit a complete/final report, but functionally we can treat it like a draft -- the teacher will provide feedback and you can make revisions and resubmit at a later date).
Mon Sept 25 - QUIZ - Graphing skills:
- in the quiz you will be given data sets and blank pieces of graph paper (you may bring store bought graph paper if you wish)
- you must apply the rules and skills outlined in the "Graphing Guidelines" handout.
- you will:
- set up the graph with an appropriate title and axis (scales, labels, etc)
- plot points using + shape
- draw either a smooth curve or a straight "line of best fit" (using a rule), depending on the trend of the data
- if it's a straight line, develop the equation of the line in the form y = mx + b
- answer some analysis/interpretation questions about the graphs
NOTE (in response to an e-mailed question someone asked me): When drawing your graphs, in the context of this course, you must ALWAYS start both axis at zero, and NEVER include an axis break. There are important patterns and trends that you will miss if you omit part of the axis. If a different case arises in a different lab, I'll tell you. In general, assume that all graphs should include zero on the axis, and should not have axis breaks.
The physics of Hurricanes doesn't really apply to the AP curriculum until next year, in AP-2, but, these items hint at concepts you'll learn in the Fluid Dynamics unit:
- Water sucked away from the shoreline in areas the storm has already passed:
- And, the reason the roofs of houses may blow off in extremely strong wind is basically the same as the reason airplanes fly (Bernoulli's Principle): http://www.nsta.org/publications/news/story.aspx?id=49598
Perhaps of interest ... There are simple, and complex, pendula ..
Simple is the sort in the on-line simulation you saw in class.
Complex could be this sort of thing: https://www.youtube.com/watch?v=J85gpcjvqzs
