A Practice Final

 

For the optics part to seem less difficult, do the Optics Practice Test posting before this.

Optics Practice Test

 

(Read the book in Chapter 14 and 15 to learn how to assign + and - signs to the values represented by the symbols p, q, and f in the formulas.) I'll do a dedicated summary of this on Friday, June 2, but don't wait for me. It is gettable from reading.

 

The key to this is followed by an example of how a solution to one of the questions could look. An algebraic example.

Magic Mountain Field Trip is Wed., May 31, 2017. That is a B day. Cost and Permission slip details coming soon. (The buses have been ordered as of 1:45 PM on May 9.)

Ray Tracing Worksheet that's due Tues. 5/16

 

This handout was provided in class on 5/10. Absent people are expected to download it here and stay caught up.

 

Technique was shown in class 5/10, much time was given for students to practice it and ask questions, and the ray diagramming technique is well layed out in Chapter 14.

A part of the key to the HW that is due Tuesday, May 16.

 

This helps people check their own understanding. (Given this type of support, I see no reason why someone would think it worth his/her time to copy the homework mindlessly from another student. Time could be better spent actually seeing what the book tells you and individually applying it - and I did it in class as well.)

DC Part 1 Notes - These mirror something we did in class.

 

Monday's Quiz (on 4/24) gets simple if you process the methods of DC Part 1 Notes, DC Part 2 Notes, DC Part 3 Notes, and DC Part 4 Notes.

 

Part 1 is quick. Takes about 10 minutes, Part 2 is quick, takes about 10 minutes, Part 3 is quick and almost unnecessary, takes 5 minutes. Part 4 is where all the effort lies.

DC Part 2 Notes

 

DC Part 3 Notes

 

DC Part 4 Notes

 

Circuit Simulator Experiment - will be due Friday April 14. You can start early, now, before the class of April 12.

 

The assignment exists on Pages 3 through 7. It's designed to be self-explanatory.

Millikan Oil Homework - Original Document (certain people were consistently absent)

 

This particular HW assignment is past due. April 10 is not really the due date. It's just the next time class meets. The due date was in March.

Resistance Simulation Assignment - Jokingly called "Resistance is Futile" in class.

This is due upon arrival on April 10. Most students did most of it during class. Many people have been frequently absent recently. Because the document is posted here and is easily doable, it's due for everyone upon arrival on April 10, regardless of absence, as was stated in class on March 30. Again, most people did this during class on March 30, the Thursday before vacation.

In class, I told everyone that using this key helps tremendously for people who got stuck. It makes it simple AND it makes you think about the important discovery and about the importance of units of measure.

Help with Calculating Electric Force

 

On the PhET assignment, this is called F-First Calc.

 

PhET packet due Monday. But finish it in class on Thursday 3/16, because you have time.

PhET Assignment on Charges and Fields - Support Document - Lesson 2

 

This is a 6-page discussion. It's for those who want deeper meaning behind that Charges and Fields assignment I'm making you do. The Charges and Fields Assignment instructions tell you what to do, but they don't say why in all places. This document talks about why. It's called "Lesson 2" in Electrostatics.

Re-posting of the All-Multiple Choice Practice Test on Waves. I re-numbered the key. Test is Friday, March 10.

A Practice Test for Waves. The Waves Test is Friday, March 10

Be Aware of the Study Guide - Posted Here. Helpful for the test of Friday, March 10

Be aware of the Wave Vocabulary Words - Posted Here. Helpful for the wave test of Friday, March 10

Beats Excel File - You have to use this to do the Bears, Beats, Battlestar Galactica worksheet

Due upon arrival on Tuesday 2/28.

 

Completion of what's assigned on this file. This file was already handed out in class. You'll also need the chart with your names on it and two assigned frequencies labeled W1 and W2.

 

These instructions were titled Bears, Beats, Battlestar Galactica on the page.

 

You'll need to use the Beats Excel File which is also posted.

This posting needs to be followed carefully by anyone who was told they needed to re-do the HW that was due and checked on 2/22/17. If your paper was handed back to you with no grade on it, then that means the conclusion is invalid and it needs to be handed in again on Friday the 24th, hopefully corrected. If your returned paper had the green Berlin stamp on it, that means its score was 100%.

 

The posted document contains information on the data collected by students in Period 2 and in Period 3. Anyone who was absent requires the posted document, because an absent person only has recorded the frequency from one station, and all four are needed.

On Friday, students will follow through on the Standing Wave results. This chart can help. It's from what students reported to me, data-wise, but student names have been removed. If there are rows that lack information, it's because the student didn't report data as it actually happened, and I wasn't able to record information in a way that matched my labels for things like L, f, Tension, N (number of half-waves.)

 

However, the rows that are complete are totally useful for anyone who chooses to open the file and look carefully at its contents. On the far right in the file, I compiled all unique ordered pairs of Wave Speed and Tension that resulted from student clearly reported data. And I graphed it. It's good. In class on February 17, students will complete work in class that follows this.

To help with Chapter 8 Quiz, which is Friday 2/3. This posted document is the notes for the solution to the 2nd Practice quiz that I handed out for this chapter. I handed out the second practice quiz in class on 2/1. (I had handed out the first practice quiz back on 1/25. The answers for the tensions in the first practice quiz were 950 N and 650 N.)

Final Exam Review Information - List of topics, book sections, and practice problems. A key is at the end.

More Review Problems for the Energy Test - This has answers at the end. It contains two problems for practice that were already handed out in class, and then it contains 4 more beyond that.

Chapter 5 Test is Thursday Jan. 12. This posting is to add practice for that test. This posting is not a graded assignment by itself.

Loop Worksheet - This is practice for Chapter 5. The test is Thursday. The Loop Worksheet isn't a graded assignment. The test is graded.

Loop Worksheet Answers

HW due Wed. This document posted, as announced and shown in class.

Fill it in and check your understanding as you go. I'm checking both effort and comprehension on the 14th.

 

You can also read about Potential Energy in Chapter 5.

Air Track Result for friction on the tape due Monday 12/12. As usual, lab assignment write-ups must show data first, and then every calculated result is defended with work shown. Students were guided by the paper titled "Air Track Assignment from Chapter 5 Viewpoint" so most people call that worksheet the assignment.  That is true, but it is a lab assignment, and #9 is the conclusion. All labwork has a statement called "Conclusion" and all labwork is handed in with Title, Date, and Data Section as the first thing stated, regardless of what the worksheet says. Once these things are established, then the numbered tasks of the worksheet are an effective way to organize the solution. Conclusion is the last thing stated. Everyone is supposed to know this, but I still get some nonsensical assignments that are hard to read.

 

The last paragraph on "Air Track Assignment from Chapter 5 Viewpoint" says something about having a packet (with Pages 3 and 4) to compare your final answer to. This will be out of context and confusing, so you can ignore that final paragraph. However, I want to replace it with something that is purely optional but something that can help you check your final answer on this assignment. That something will be a different posting on Edlio and I'll call it "A Way to Check Your Air Track Friction Answer".

 

Finally, there is something nice posted here. It's an example of a solution of this particular assignment. It mirrors the example I did on the board and strongly encouraged students to engage with on Thursday, December 8. (I said "follow the logic and calculate it while you're here; rather than photographing the board to look at later." That's what I mean by "engage with".)

Helper Page for Checking Assignment Due Monday 12/12 (full assignment discussed elsewhere.)

I posted that I'd make you something called "A Way to Check Your Air Track Friction Answer." This is that posting.

This closely mimics something that I gave you awhile back called "Physics Test Excerpt". I had given you that as a thing to use for practice before the Chapter 4 Test.

 

(In case you're wondering, my mentioning of a "packet" with pages 3 and 4 on it, the paragraph I said to ignore in the other posting, basically was related to you already having used "Physics Test Excerpt". You don't need to know any more than that. I just basically wanted you to know that I was trying to provide you with something helpful so you can check your final answer. This new posting will now serve that purpose in a succinct way.)

Newton test grade will be determined by taking your Scantron number correct, adding 23 to it if you followed directions during test-taking (not writing on test, name on test, etc.,) and then dividing that sum by 50. Example: missing 7 on the Scantron yields a Scantron score of 20. Adding 23 to that yields 43. 43 divided by 50 is 0.86. That is considered86%. The assignment in the gradebook will be a 25-point assignment. The example grade would be recorded as 86% of 25.

 

If someone did not follow directions during test-taking, then 21 points is added to the Scantron score instead of 23.

A Chapter 4 Test happens on Wed. Nov. 30. This posting is the 2nd of 3 review documents for such a test. This is a concept review, and has various exercises, and the last page is answers for checking one's progress.

A Chapter 4 Test happens on Wed. Nov. 30. This posting is the 3rd of 3 review documents for such a test. This is an excerpt containing samples of some questions I've put on tests in the past.

Your HW, "Energy and Power" worksheet should be quick work, because I said I'd post something here to help today, Sunday.

Here it is!

 

It's the final answer to the last question that's the most interesting.

Original Assignment:" Energy and Power" This is the original assignment sheet. There were a few absences when I assigned this. No reason not to stay caught up and do it anyway. Anyone who reads the assignment sheet can see they can do the activity anywhere they can find a stair case or a hill to climb. And then look at my other posting which shows an example of exactly how to do the math. If someone comes to me and says "I wasn't here, so..." about this assginment, I'll briefly tell them," please look online." Everyone is covered.

A Practice Test for Chapter 4. Do it all before looking at answers at the end.

Real test is Wed. Nov. 30.

Exp. 6 is due Friday (along with 7). People should know that the solution method of Experiment 6 is almost identical to Tutorial 2, which was handed out weeks ago. Here is an additional copy of Tutorial 2. Experiment 6's assignment was to solve for the friction and solve for the normal acting on M in the given pulley scenario.

Excellent! Many good g calculations for other planets by many people during class. I'll post the key to that sometime on Tuesday. Otherwise, before Wed. Nov. 9, just identify and be ready to look at any things in class that you might need to catch up on. For example, a lot of people are still incomplete on Mystery Mass.

Gravity Weight and Mass Worksheet is due Monday Nov. 7 upon arrival. Stuck? No problem! HELP IS HERE. The Word document in this posting is that help. It's 2 pages, very useful, very thorough; it's like having your own private tutor helping you. Use it! It's the main thing I promised I'd post when I made the assignment in class. All of this is by design: the last lesson, the Interactive Physics Activity, the "Gravity  Weight  Mass" worksheet, me assigning it, me telling you I'd post stuff online to help you, this Word document - this was all thought out ahead of time to give students many paths to success. So use everything I'm making for you.

I'm going to post two more things that are less important but still useful: 1) I'll try to post a chart of radii and masses for the planets of our solar system, and 2) I will post a summary of the lesson notes from the class of Thursday Nov. 3.

This post here is just the class notes from November 3 - should be very helpful for anyone. This accompanies the assignment that's due Nov. 7. Look at the other Nov. 7 postings to be completely sure of what I said is due Nov. 7. (And I said it in class, and I said in class that I'd post on Edlio twice to help with the HW, and those two postings (and more now) are on Edlio, all dated Nov. 7, so there should be no confusion at all about what's due November 7.)

This is a blank copy of The Gravity, Weight, and Mass assignment sheet that is due on Monday Nov. 7. (Some students lose their worksheets so I'm posting it again here. Most of you will not need this, because you got it in class and didn't lose it. Make sure you read the other November 7 postings - all of them.)

Planetary Data Chart - Here it is posted. This isn't necessary for doing the HW, but it's extremely useful, as the other helpful stuff explains. Pay attention to every other posting on here that's dated for November 7. Those other postings are crystal clear about the homework, which was also talked about verbally in class.

Read and learn this solution to the quiz that happened on Friday 10/28 if you were unable to do it in class on Friday 10/28. Writing in bold in the posted document is the solution part. The rest is the quiz text that was given to all students on the 28th.

Tutorial 5: This is very useful to go with the Mystery Mass. There are a couple of ways to lay out the algebra of that scenario, even though they have identical physics. So this Tutorial 5 order of steps looks a little different from the original Mystery Mass worksheet. Getting to the same answer through both is good for you. Or you're allowed to prefer one over the other. Either way, this document helps you assure you are getting a good lab answer for that Mystery Mass Experiment 5 which is due Oct. 26 and which you should work ahead on.

More Help on Mystery Mass Here! I call this brand new document "Tutorial 5 - Version 2". Why did I write it? Because many people are denoting their heavy mass in class with the symbol M2, which is fine, but Tutorial 5 (original document) denotes the heavy mass with the symbol (M+m), which is also fine. Both methods work, but because of the naming discrepancy, I thought some students would appreciate seeing the algebra laid out with symbols specifically in keeping with the M2 labeling.

 

Another nice thing that I added to Version 2 is a third page with a section I called "Algebra Appendix". This is just some assistance purely with the simplest way to do the final algebra steps in the problem.

 

Another thing that I put into Version 2 are the actual Free-Body Diagrams I would use in such a problem. These are diagrams that all students should have already made 4 days ago. Version 1 talks about those diagrams, assuming that all students would do them. Nothing wrong with the Version 1 approach either. Either way, you have lots of help here.

 

The quiz of Friday October 28 is all about using Newton's 2nd Law in relation to Free-body Diagrams. That's what the following practice documents are all about: "Tutorial 1", "Tutorial 2", "Tutorial 5 (Versions 1 and 2)", and "Dueling Forces". This is heavy support, and there will be no surprises on that quiz.

Tutorial 1, Chapter 4: In class, I wrote on the board to work through this by Monday 10/24.

There is also a quiz on the same topic on Friday of the same week.

The Tutorial 1 document is self-correcting so when you try and do it on your own and read what it says for consistency, you learn the topic. On the other hand, when people think they have to have someone do it for them, like a tutor, it can be distracting. Do it on your own, and I'm open for questions. There is no way to be wrong. My document already is the tutor (that's why it's called Tutorial), so money and more time need not be spent elsewhere on this.

Advanced Chapter 2 Practice: This one is harder than the test, but is extremely good after you have done the other fundamental practice that I've been mentioning. If you feel like you have to catch up before Tuesday 10/4, then you should work on the other study/practice things I've posted before Tuesday. Saving this Advanced one until after Tuesday will not hurt you. But once you feel strong with the normal Study Guide stuff... Ever wonder whether a launched toy rocket should take the same time going up that it takes coming down? How about it's speed upon hitting the ground in relation to its launch speed? Well...

(And if you have a favorite rocket kit of your own, feel free to ask me about bringing it in for class time. Even stomp rockets are good.)

I post things in "Assignments" for convenience. It doesn't automatically mean they are collected. All students are supposed to know we have a test coming and that these documents are to help them with the practice problems for the test. Practicing for the test before Tuesday is required for success on the test that is Thursday, and I'm not collecting anything on Tuesday. All of these postings that say "Due October 4" should be very valuable for the practicing students and are to be used before Tuesday even though nothing is being collected on Tuesday. It's free problem help from me outside of class, and it's in thorough written form.

Solution Document (PBS) for the "1D Kinematics Review" paper that was given to students on 9/30 in order to practice for the test on 10/6. Setup was discussed thoroughly, and students were given the answer to go home and prove. Every student should be doing that to solve the problem on one's own. In addition, after doing that, those students may also have this extremely thorough breakdown (posted here) of the algebra and how the math steps of the solution should look. But there is SO much more to this than the math. And that SO much more is also reviewed in this attached document. Every listening student should know to absorb this BEFORE Tuesday in order to be ready for a test that is Thursday. The reason for that was explained in class. Also, some people in the past have said, "I wish Mr. Warren would show the whole use of the formula, and not just talk about the setup." That is a false characterization of my work, because I always end up putting the whole use of the formula in my documents like the one posted here. People who listen in class and access the documents on time see that I talk about the setup of the problem thoroughly AND I write out the formula for the solution thoroughly (and quite often I do the formula part in person as well as on paper.) I give many modes of access to all the material. If anyone disagrees that the formula part is written out, they can bring this printed paper and show me what they mean, and I'll fill in what they say is missing. This is not a contest or an argument. Student communicates why they disagree, and I will give them what they want. But it's only possible if they communicate.

Answer Key for Study Guide Book Problems - I said I'd post these ALL, because the book only gives you the odds. Here they are. You can train with the book problems and see if you are proving the answers on the key BEFORE looking at the key. The good problems to use are on the Study Guide. The Study Guide book problems are a very good representation of the algebraic part of the test.

Right here is posted another example of problem-solving set-up so that you can have a simple time preparing yourself for the quiz of Monday 9/26. Two examples were done in class and a stapled packet was handed out with another example, and it was stated that you will be graded on the set-up notation that you write and not the final answers. The stapled packet is more challenging than what is posted right here. What was done in class and that which is posted right here should be more than enough example to prepare yourself with confidence for the Problem Set-up Quiz I have in mind for Monday, 9/26. Once again, the equations to use that you do NOT memorize are on Page 58 of your book in the blue box. For what I've done so far, focus on 9/26 is only on the top two of the four equations. These two were clearly stressed in class in the example I did. Any testing or quizzing will assume that the student has those equations to look at while doing the test or quiz. A student who has the equations available still needs to practice their use. There are five symbols to interpret: t, vi, vf, a, and delta-x. The physical interpretations of these five symbols is the main idea. It is neither easy nor difficult. It requires awareness. Work to know precisely what each symbol means physically, and use the practice I provide to get better at this skill. The units are a big part of this. Very similar to what I post here, you can find four more textbook problems to use for practicing on your own. These problems are the 4 problems at the bottom of Page 55 of the book. Use the equations on Page 58 to set up the problems of Page 55. The answers to the problems of Page 55 that you're working toward are: 1) 9.9 m/s and 30 m, 2) 19 m/s and 60 m, 3) -7.5 m/s and 19 m, 4) 2.5 s and 31.25 m. Measure your ability to get good at setting up the problems to PROVE these answers. Do not memorize any formulas.

First Write-up on Free-fall - Helpful Attachment

Note about Free-fall Experiment 1 Write-up due: Being uncertain or incorrect about any numbered item on the paper assignment sheet is not a problem. You were told in class to always focus in a write-up on answering the main objective. If you do that, the numbered tasks on an assignment sheet become like a set of hints. If you don't "get" one of the hints, but still answer the main objective, all is well. It was stressed heavily and repeatedly that the main objective of this experiment comes from the slope of the velocity versus time graph. People who arrive to class with that figured out will do well.
