AP Ferry Boat Lab

Make it a brief formal lab due Thursday for Section 1. Include all the trig with brief discussion of why what you did worked. Procedure can be pretty minimal. Focus on the idea of adding boat wrt to water + water wrt shore to get boat wrt shore and how you used components and trig.

Honors Free Fall Lab

The velocity vs time graph should be a straight line and so it is its own tangent. I wanted you all to realize this and to think about the fact that your velocity graph had a constant slope and what this means about the acceleration. The velocity graph should cross the vertical axis a bit above zero since the weight was already in motion at what you used as your zeroth data ( length = 0) point. In other words you started using data a few intervals into the free fall; you did not start using data from the very beginning of the fall, so the velocity at your zeroth length point was already greater than zero. Hope this helps and next time do the lab sooner, while it is all fresh.

AP Retest

I just finished writing the test. Some of the questions are very different from the original, not harder, but different. Be sure you know the definitions of a and of vavg and how to use them to find delta t and to find delta x. Also be sure you know how to use the displacement = vf^2 -vi^2/2a to find vf or to find a.

Honors Free Fall Lab

Question 7 should read compare with actual position i.e column C not column B as printed

AP Retest

If you received less than a B- on the first quiz you can take a retest on Wednesday outside your class hours or outside class hours on Thursday before end of day. You must have a 90+% on homework and, if you had a see me on your last quiz, you must discuss it with me before you take the quiz. You must sign up in the appointment book so I know who and how many I am dealing with. You must also bring your old quiz in.

The retest grade will be your grade and no matter how well you do, it cannot exceed a B- i.e if you do earn a B- say 80/100 that's what you get. If you earn 97/100 you still get a B- ( but you can be pretty happy with yourself)

Home Access Center and Grades

Because I use individualized weightings to reflect your own wonderful individual wierdness, oops , I mean charming characters, and because Eschool cannot accomodate this, I keep my grade book off line on a spreadsheet. This means that posting grades on Eschool (HAC) is double work for me. Even so I will try to post grades in 3 categories [tests and quizzes; labs; and homework] every 2 weeks or so. Honors and Topics project grades will be posted occassionally. Only the grades in categories are significant. HAC calculates the overall grade in a way that may resemble your overall grade for some of you, but don't count on it.

I am often hesitant to post grades because a retest that will change the currently grim picture is coming up soon, or I just know that lab resubmission is coming in tomorrow, but the flip side is that if I keep putting it off, your folks don't see where you are not keeping up. Therefore I will post the grades as they are and let you explain it to Mom and Dad. [To parents: let me know by email when you have a concern. I usually get back within 24 hours.]

Now here is the bonus: 10 points of extra credit if you print this out and bring it in with your parent's or guardian's signature.

Honors Retake

All who received less than a B- on the first quiz can take a retake on Wednesday, before or after class. Requirements are:

you must bring in your first quiz,
you must have seen me before you take the test if your test says to see me
your homework record must be up to date

Areas you are expected to be familiar with which were posted before the original quiz still apply. Of course, questions and emphasis will be different from the original quiz.

Good Luck

Labs

Unless labs are fill in the blank types copied from manuals assume they are formal reports unless told otherwise.

AP problem with two forces pulling log

Fnorth total = FN1 +FN2 = 1000 cos 45 deg + 1000 cos 120 deg = 707 -500 = 207 N north

Feast total = FE1 +FE2 = 1000 cos 45 deg + 1000 cos 30 deg = 707 + 866= 1573 N east

boy must provide 207 N south to make F north = 0

AP Vector lab

Many of you did not include a purpose as requested in class, but not posted until 9/18 on this blog. I will forgive the -6 points this time but: Next time listen in class, anything announced in class is required even if not posted. I will also forgive the -3 points for those of you guilty of not stapling the purpose since you probably turned the purposes in on Monday.

A large number of you did not label your sketches with the force or which vector was A+B. Many of you failed to draw arrow heads indicating direction.

Many of you failed to follow simple directions. You were to draw a sketch showing A +B or B +A (same result of course) and then label the result A+B and measure its magnitude using ruler and the scale you developed. Then, on a separate sheet you were to draw A+B+C.

This time you lost ten points for not doing two separate sketches. Next time you leave out a task or fail to follow important directions your loss will be greater.

(Honors read this too) AP Vector Lab

Several of you in your labs added vectors as if they are simple numbers.

First of all you were to supposed to read your ansers from your sketches , measuring the resultants with a ruler and then converting to Newtons of force using your scales ( such as 5 cm = 1 N or whatever you chose). Thus, you should have been addign numbers at all but pictoral vectors.

Second: a 2 dimensional vector is not a number. It is a pair of numbers i.e. the x component and the y component or the East component and the North component. Sums of vectors are found by adding all the x compoenents to get the resulting x component and then the y components to get the resulting y component. The result or resultant is a new vector also comprising two numbers: its x component and its y component.

Magnitude has no sign. It has the value = square root of (x component ^2 + y component^2). It can be found from the length of the vector x scale factor For example the magnitude of the force = 7 cm measured x .2 N /cm = 1.4 N

All Honors and AP Labs

1) All parts must be stapled together. I am finding bits and pieces instead of complete reports. This is even worse when you don't put your name on the pieces. Put you name on all graphs, data sheets, etc. ( staples do fail to hold pages together sometimes) and then staple them in the right order. You are no longer in kindergarten where you teacher does everything for you.

2) You will often find instructions about your labs and lab reports here on this blog. If you do not follow these instructions you will lose points. It is unreasonable for you to expect me to allow students to fix their labs after submitting them without the items or work asked for.

For example some vector labs came in without the sketches of the vector addition.

All Students Extra Credit Assignments

IF you do extra credit assignments you MUST write Extra credit and the number of the problem or its name or some other way to identify it at the top of the page. Then also identify the problem as extra credit where you wrote the problemWe do not have time to hunt through 100 papers to see who did the extra credit.

AP and Honors Cardinal Sin

DO NOT EVER TELL ME that delta t = delta x/ a This will lose you full credit for whatever problem you use it in.... and that's just the beginning!!! x and v are not the same thing!!!!

AP and Honors Area under curve

The area under a curve does not have the dimensions of normal area. A graph is a representation of data, not a picture of acreage. The units of area under a curve are the units of the vertical axis x the units of the horizontal axis. For example, areas under a v vs t curve have units of meters ( or cm if you use cm) /sec x sec = m ( or cm)

units of an acceleration vs t (a vs t) curve are m/s^2 x s = m/s Thus the area under the a vs t curve equals change in velocity.

Areas under force vs position curves have units of Newtons ( units of force) x meters or Joules. Note that area under force vs position has units of work (Joules) since work = force x displacement. ( honors should understand this, AP will soon).

Honors lab

The lab we did Friday ( we'll do it Tuesday for Section 1) should have a formal write up - see the course guide. To do the lab, you will need to remember all the things we said about grahs of position and velocity, and slopes, and area under the velocity vs time curve. Use graph paper, show your calculations of slopes and areas in the discussion section. It is due Wednesday for Section 2.

Honors Unit 2 WS 1

For question 6 use 3 seconds as delta t. Also answer the following . During this time, what was the car's average velocity? How far did it travel and in what direction ( i.e. what was its displacement) while it was braking?

Honors Labs

Got lots of good labs from Section 1.

For section 2, most labs are being returned asking for the descriptive paragraphs mentioned on the blog. Since it most of you didn't see the blog in time, there will be no penalty to your grade for not having submitted the descriptions the first time around as long as I get them by Wednesday.

Please do graphing on graph paper and be neat. Our next lab will require neatly and accurately drawn graphs to be successful.

AP Lab

Make sure you include your calculations of time of flight an vi and then new time of flight and predicted delta x. Write equations first then with numbers plugged in.

data are delta x delta y and theta. Discuss accuracy of prediction and conclude whether or not your equations are valid. Make sure you discuss spread in values, it makes agood excuse for being off by a few cms. Also being off by 5% is more of a confirmation than an invalidation of your equations.

Honors Physics

Please note the following link for the the report on the European Fusion Power Plant report. Download the summary and full report. It has lots of good stuff we will use on our projects.

Notes on AP Labs Honors read these too

Labs were pretty good , many excellent but here comes the "but"

1) Please include calculations in body of report or, if you must, NEATLY done on easily identifiable separate sheets.

2) When drawing tangents to find slopes extend tangent line to edges of graph to get most precise results . A 1 mm error is 10% of 1 cm, but only 1 % of 10 cm.

3) In this lab you were asked to compare your measured acceleration with g x hanging mass/ mass of cart. It should have said g x hanging mass/total mass, where total mass = mass of car plus hanging mass .... after all they are both being accelerated by the the force on the hanging mass. Many of you ignored this question simply because it was not one of the numbered questions and appeared early in the lab.

4) Everyone dutifully said that the slope of the velocity vs time is a, but almost no one used this slope to answer the question referred to in 3 above.

AP Practice Problems

Note for Practice Problem 1 magnitudes are A:70, B:80, and C:100 and no Brian, I don't know what the units are!


Angles are
A: 0 deg from y axis

B: 50 deg clockwise from -x axis

C: 70 deg clockwise from - y axis

AP Shooting for A+ Lab

As part of your lab, calculate the variation in your intial results for either horizontal distance or vi as a percentage of the average. See if your percent error on your prediction with theta not = 0 ( i.e. today's result) lies within this percentage.

Calculator

I am in possesion of one more calculator than I was yesterday. While its nice, it would probably be happier with its proper owner.

Honors Unit 2

We'll be doing some conventional physics for a little while. Here's the schedule and worksheets you'll need for a while. I hope the text comes in soon and I'll revise this. Just download the schedule, both Math reviews and Unit 2 1-D worksheets 1 and 2 for now. I may change Sheet F-1. If I do I'll let you know before the schedule date. Read both math reviews. The one for Math Physics is pretty basic but should be helpful. You must do questions 2,9,12,13 and 14, of the Math Hnrs worksheet but try the rest. No extra credit this time.

Homework

Homework is assessed to see if you made the effort. It doesn't get graded as a quiz. Exceptional work may receive extra credit. Underdone assignments will receive less than full credit. It is to be turned in on day due.

It is also used as a tool to see where extra attention is needed.

If you need help on an item flag it at the top of your homework and identify what the problem is, not just the number of the example.e.g. how do you find vf in #39 is much better than just #39.

Honors Lab

For the lab we did Friday and Monday, which is due tomorrow ( section 2 ) and Wednesday (section 1), we are not preparing formal reports yet. What I have asked you to do is prepare 4 graphs: a position ( or cumulative length) vs time graph and a velocity vs. time graph for both the constant velocity run and the acceleration run. While you are at it, prepare a brief description of the graphs discussing each one's "shape" such as straight and diagonal upward, straight and flat, or curved upward or downward. Add a few words as to why you think it had that shape. We will use these labs and graphs soon in classwork and in lab reports to learn more about motion.

Make sure your stuff is stapled together and has you name and period or section on each page.

Honors Assignment

Here is a summary of the main systems of the plant. Since we haven't gotten our texts yet I won't hold you to naming the area of physics associated with each plant system

1) Plasma;2) neutral beam heating and other heating systems; 3) first wall and blanket; 4) magnets; 5) cooling and conversion of heat to mechanical energy including steam turbine; and 6) converting turbine mechanical energy to electric energy i.e. the electric generator.

General Lab Information

Use full pages for graphs even if you are using a spreadsheet or other program. This is especially important if you are finding slopes or areas under curves. Use graph paper if doing by hand and label axes and supply values for each axis.

Use best fit lines. Do not connect the data points with straight lines. Best fit lines do not have to go through every point and are not necessarily straight lines, for example position graphs for motions with acceleration should be parabola (but don't fake it if your data doesn't justify it.)

If you use a spreadsheet most spread sheet programs have a slope or trend line feature. Pick the one that makes the most sense ( say linear for velocity or 2nd power for position when a = constant)

Calculations such as those for slopes or area must be shown in your reports.

Conclusions should relate back to your purpose ( or your purpose should connect with your conclusion). Conclusions should be pretty objective such as "gee acceleration did = force/mass" rather than "boy I learned a lot."Make sure you answer all the questions, even if the answer is my data didn't give a clear answer.

Use lower case v for velocity. Upper Case V is volume or Volts

Centimeters vs Meters

If you persist in telling me that (50 cm-10cm)/ .4 sec = 100 meters/sec I will lend you a nickel and require $5 in return. Last week is the last time you could do this without loss of lots of points!!!

Honors Expectations

I would ( if I were an optimist) expect you to know or be able to:
briefly describe kinetic and potential energy
know something about what makes things go in a circle
why a fusion reactor is so desirable
definitions of fusion and fission
some typical fusion reactions
the reaction most likely to be used in fusion reactors
how to explain why the reactor plasma temperature has to be high
why fusion reactions yield particles with high kinetic energies ( sneak something about E = mc squared in there)
why you can't let plasma hit wall - 3 reasons or more
what requirements are for first walls ( including low potential for becoming highly radioactive)
how you confine the plasma including some discussion on how magnetic fields affect moving charged particles ( you probably even should throw in an equation)
how you get work out of a gas ( another equation would be nice here)
provide a brief discussion about how you use a magnetic field to generate electric power or energy

Honors Motion Lab

Save your silver tapes and put your names on them. Plot position curves, in other words column B vs time.

AP Vector Lab

Reminder, for the vector lab I should receive the lab packet and two sketches showing the two vector additions, plus a written or typed purpose statement.

Honors Notes on Steam Cycles

This should help with your homework, but give the thermo notes from the previous post a once over so we can make rapid progress about cycles tomorrow.

http://h1.ripway.com/DrCherdack/Notes%20on%20Steam%20Cycles.doc

Don't worry about the incomplete sentence concerning adding heat. Its a little complicated and I'll give you revised notes later

AP Mastering Physics

The deadline has been changed for assignment #2 to Monday AM

If you missed the deadline for assignment 1 turn in hard copy.

Honors Extra Credit

We discussed how the magnetic field can make a single particle orbit around in circles, but we didn't get to cover the interaction between plasma as whole and the magnetic field. This interaction with the plasma is what the extra credit was about. We'll go over this in the next day or two and then you can have another crack at the extra credit.

Honors Physics

It looks like we are running about 1 day behind schedule. Therefore I am changing your assignment for tonight to reading the following.

http://h1.ripway.com/DrCherdack/Heat%20and%20Energy%20Conversionr2.doc

All other assignments for this unit will be due one day later than the schedule shows as will be the quiz.

Honors Physics

I am afraid you may be feeling a little neglected at this point. I will be providing a list of sample questions indicating the sort of thing I expect you to know when we get to our quiz next week. Look for that post in the very near future.

Again, at this time we are looking at the overall nature of what we need to learn to design a fusion power plant and how we can put individual bits of knowledge together to answer the kinds of questions which must be answered to design something. We will explore each of the areas we are discussing much more slowly and in much greater depth, but with the understanding of why we are exploring it and how it relates to other topics. I am hoping that with each new exposure you will find an area you find exciting or at least interesting to take on as your specialty.

I do not expect any of you to be able to reproduce any of the calculations we have made to date, but I do want you to get used to the process of using quantities and relationships to develop new information without being told exactly what to do. This a long term goal and if we achieve it, it will make you more valuable to yourself, your community, and your employers.

Topics in Physics Thermo Question

In our 7th period class today Alex asked how can a Carnot cycle be the most efficient, if going from point C back to the adiabatic line from point A via an isobaric process requires less work into the gas than going from C back to the adiabatic line using an isothermal process. For convenience lets call the point where we reach the adiabatic from A as point D. We can reach this point D from point C with an isothermal process or an isobaric process.

The explanation is subtle. The efficiency for a cycle must be considered in conjunction with the temperature limits it operates within. In other words, when comparing types of cycles, one must compare them with the same heat input temperatures and same heat rejection temperatures. In order to compress isobarically from C to D one must be reducing the temperature. Therefore Alex's suggested cycle either would require a lower heat rejection temperature (the low temperature point would be at D only rather than the whole line from C to D as in teh isothermal case ) than the Carnot cycle, which would allow it to get cooler going from C to D and thus have better efficiency, but only because the heat rejection temperature is lower, or it would have to have a point C at a higher temperature than the point C for the Carnot cycle, so that the temperature at the isobaric D would match the temperature of the isothermal point D) which would give it a lower efficiency.

More AP Stuff

1) Quiz, You must know the definitions of displacement, velocity ( average), and acceleration in symbol ( equation) form. You will be given the three equations relating delta x to velocity, time , and acceleration. You should be able to manipulate theses equations and definitions to find the required quantity, such as delta time in a free fall situation.

2) You should have received an email with your ID for the Mastering Physics Online Course, this is your personal ID number for me to track your work. The course ID is MPCHERDACKAP1. The Course Title is AP1. Register for the online course using this information plus the packet you received with the text. Let me know if you did not receive the ID email. if more digits are needed for the ID just place zeroes in front of the number I gave you

3) Several of you did not receive the email because I do not have an address for you. These include Cal, Kevin S., Sean, Katelyn S., Corey

AP Lab Cart mass

The cart mass is close to 500 g. or .500 kg. Use this number to figure out what the acceleration should have been based on a =F/M where F = the force on the weight pulling the cart = Mhanging mass x 9.8 N/kg and M is the combined mass of the hanging weight and the cart.

Note that in the equations for delta x and for vfinal substitute delta t for t. In many books and on materials for the AP t is used in pace of delta t. This is okay if t initial =0 but it is not correct in general.

AP LAb and Assignment

1) Lab: Section 1 is due tomorrow. Since we didn't get to the lab in Section2 we will do it Wednesday and it will be due Friday.

2) All AP sections solve the following ( you should recognize some of it from class) An object starts with a velocity of 10 m/s, and accelerates uniformly ( a is constant); it covers 90 m in the first 3 seconds; find the velocity at 3 seconds, find the distance covered in six seconds ( total time is six seconds not six additional seconds); find v at six seconds; find a. It may pay not to do these in the order asked.

AP Lab

The lab report is to be formal and is due Tuesday.

AP Lab

1) Note your first graph should be a plot of position not change of position ( x not delta x). You should plot the distance from the point to the origin not to the previous point. Note that your point from which you measure , i.e. your origin, is the zeroeth point in my nomenclature

2) Time coordinate. When plotting your graphs, do not use the number of the time interval as the horizontal coordinate. use the actual time in seconds. Thus, if you chose every third point, your time interval is .05 seconds and your time scale should be labeled .05, .10, .15, .20, etc.

3) Graphing the velocity. Note that by taking the distance at time n and subtracting the distance at time n-1 from it and then dividing this difference by the time interval ( say .05 seconds) you find v. However, the v you found is not the v at time n. It is the v 1/2 way between time n-1 and time n.
Keep this in mind when you plot your v graph. So if you are looking at 5th and 6th points and your interval is .05 sec the velocity found from v= (x at .3 sec - x at .25 sec)/.05 should be plotted with .275 sec as its horizontal coordinate i.e. halfway between .25 and .30 sec.

4) Do not call the vertical axis the y axis or the horizontal axis the x axis.

5) In naming a graph use Vertical axis name vs horizontal axis name ( the vertical come first).

Chapt 1 problems

Here is some help for some Chapter 1 problems. Note solutions are not always exact but you should be able to get correct answer using the methods I present.

Problem 22 from Chap 1.

77 m + 813.8 m = 890 m or something between 889.5 and 890.5 m

Sum of two possible minimum values is 76.5 + 813.75 = 890.25

Sum of two maximum values is 77.5 + 813.85 = 891.35 so all possible values lie within 889.5 and 890.5. If we had said our answer was 77+ 813.8 = 890.8m that would have meant something between 890.75 and 890.85 which would not have included all possible values.

Problem 36 from Chapt 1 [coasts seems to mean maintains speed although most of us slow down when we coast]. In any case velocities for the zeroeth through 8th second are 0, 5,10,15,20, 25,25,25,25 m/s. Distances for the same times are: 0,2.5,10,22.5,40,62.5,87.5,112.5,137.5 m. Note you can find distance during acceleration simply by taking velocity at that time and dividing by 2 to get average during interval from start to that time then multiply by the time. This is the same as delta x = (a delta t) /2 x delta t or

delta x = a/2 delta t ^2. For last 3 seconds just add 25 m to position at previous second.

Problem 37 from Chapt 1. For easy arithmetic assume g = 10 m/s^2.

Can do this lots of ways easiest is use (vf^2-vi^2)/2a = delta x and rewrite for vf

vf = sqrt(vi^2+2a delta x)= sqrt ( 0+2x(-) 10x(-)30) = sqrt 600 = 24.4 m/s call it 24 [ note both a and delta x are negative]

for picture:

v is zero at start

at one second velocity is 10 m/s down after 1 second at 5 m down from start

at two seconds v is 20m/s down at 20 m down

watermelon reaches bottom in about 30m/((0+24.4)/2) =2.44 sec call it 2.4

40. delta t = (sqrt ( vi^2+2adelta x) –vi)/a = .37 s [note the sqrt term is just vf which comes to 6.3 m/s here, and that a is negative and delta x is positive]
just to check v avg =(10+6.3)/2 = 8.15 m/s vavg x delta t = 8.3 x .37 = 3.0 m


picture shows a =10 m/s^2 down and v = 10 at 0sec, 9 at .1 sec, 8 at .2 sec, 7 at .3 sec and 6.3 at 3.7 sec at impact.

AP Equation for delta t

In addition to your assignment, I am asking you to develop an expression for delta t if given vi, a, and delta x, starting from the two equations

delta x =( vf^2-vi^2)/2a and delta t = (vf-vi)/a.

Its ugly, but easier than using the quadratic equation to find delta t from
delta x = vi delta t + a/2 delta t^2.

Good luck and don't work too hard on it. Bring in what you've done and we'll go over it in class.

1) Many miscreants ( look it up if you have to) in section 1 ( period 2) managed to leave without entering their book numbers on the sheet. If you haven't entered your book number you must do so tomorrow. Without a book number I will not be able to check in your book when you return it. Your folks will be justifiably annoyed when shelling out the 180 or so bucks.

2) Those of you who have not yet turned in your old book from the summer do so ASAP so we can get this cleared up.

3) Still waiting for email addresses from about 1/3 of you.

4) Talk about miscreants, after our long talk about files and colors and in and out, most of section2 (period 4) left without depositing their summer assignments, fix this tomorrow!

Links to the course guides for Honors and AP Physics are to be found below. Please print the appropriate one of these out and read it carefully. Ask your parents/guardians to do the same.

You must bring the signature page in, signed of course. This is serious because you cannot participate in labs unless you sign the form and turn it in. Do it by class Wednesday and get 10 extra credit points.

If its not in by Friday -10 points.

The proverbial carrot and stick.

Have a good weekend and holiday.
