HW before break

The following is due before break:

Egg Drop Interactive (make sure your name is on it and your partner turned it in)

Impulse Practice

Egg Drop Pre-drop analysis

Egg Drop Craft

If you got less than 75% (less than 51/68) on the test, AND you showed me your completed study guide before the test, you can do test corrections.  For incorrect multiple choice write a sentence explaining the correct answer.  For other problems solve correctly.  You can turn in test corrections after break.

In class work, Wednesday December 17

Good morning Galileos and Einsteins,

I am out sick today. Here is what you should work on in class:

Check your HW from last night (momentum practice) and put it in your Drive folder.

Find the "Egg drop interactive" document in the Momentum folder.  Work with a partner to complete in class.  Anything not finished can be done for homework.

Momentum HW

For tonight- Momentum practice in the Momentum folder.  Egg drop due next week.

HW after test

-Check Aspen for missing work.  Make sure "Friction Practice," "More friction problems" and "3rd law practice" are also in your folder.

-Read on The Physics Classroom, Physics Tutorial, Momentum and its Conservation, Lesson 1 parts a, b and c.  Take notes on the definition and units of momentum, as well as what can increase or decrease momentum.

Newton's Laws Test

The HW tonight is the Newton's Laws study guide.  Remember, you must come in on Thursday with a completed (that is, every problem attempted) study guide in order to qualify for any test make-up opportunities.  Also the bar for retakes/corrections will now by 75%.

Review your notes and worksheets.  Like the last test, there will be a lab practical component.  Review your labs as well!

Hw- 3rd Law Practice

HW tonight is 3rd Law Practice.  Test on Friday/Monday.  We will start the study guide next.  Remember, NEW RULE: you must show me a completed study guide this week in order to qualify for test corrections/make-up.

More friction HW

HW for the weekend: "More Friction Problems."  The second problem is challenging, but you should try and work through it.  You may need the kinematics equations- search for a PDF of the MCAS Physics Formula sheet and save it to Notability.

Friction HW- Wed night

HW is in the Newton folder, called Friction Practice.  One of the formulas didn't copy over.  The missing formula is friction force = coefficient of friction x normal force.


Reminder that progress reports are coming out soon.  Please make sure you work is turned into your folder (see list below).

Friction lab

HW: finish the friction lab (graph and calculations).  Please PRINT this lab to hand in for class on Wednesday.  I will be in the computer lab on the 2nd floor Wednesday morning at 7:15 if you need help printing the lab.

The following things should be in your Google Drive folder:

-calculating weight HW (w=mg problems)

-Free Body Diagrams (truck, pig etc)

-All Felix FBD

-Scooter data sheet with graph completed

-Video (on Educreations, you or your partner)

-Comic 

Newton Comic Strip

HW: finish the skateboard graph if needed, then turn into your folder.

Also, do the "Newton Comic Strip" found in the shared folder.  This will be due WEDNESDAY MORNING.  We don't have class that day, but you should turn the assignment into your folder by that time.

Almost forgot- test corrections are due next week at well.  Turn them in during class next week or come find me on Wednesday.

HW- Tuesday night Nov 18th

HW tonight is to do the Felix Free Body Diagrams.  You will need to calculate acceleration for several of these.

There are two files in the folder called Felix FBD.  One has pictures, one doesn't.  In either case you must draw a FBD.  However, you can choose which file to complete the HW on.

Weekend HW

Galileos and Einsteins, finish the FBD homework that we started in class.  Newtons will do this Monday night for Tuesday.

See below about the test corrections.

HW, Video, and Test Corrections

HW: Calculating Weight Practice

Video: You will get 5 minutes at the start of the next class to record your audio for your video.  You should have all the slides with pictures and text ready to go.

Test Corrections- If you earned below 80%, you may do test corrections up to a max of 80%.  All answers should be recorded on a separate piece of paper and turned back in with your test.

For incorrect multiple choice questions, choose the correct answer and write a sentence explaining WHY that answer is correct.

For all open-response problems please redo the problem.

HW after test

Reading in The Physics Classroom: Newton's Laws, Lesson 1 parts a, b and c and d.   You should pay attention to

1. How Galileo and Newton's ideas changed our understanding of why things move or don't move
2. The definition of inertia
3. How you could predict if an object will change its motion or not. 
4. The difference between balanced and unbalanced forces.

Test this Friday

You should FOR SURE have a calculator.  If you borrow a calculator from me it will cost you 5% of the test grade!!


Before the next class (either Wed or Thur) you should work on the Kinematics Study Guide.  We will go over it in class- whatever we have time for (not the whole thing).  I will post an answer key Wednesday after school.  I will be available for extra help every morning at 7am and Wednesday and Thursday after school.

Projectile Motion Practice Problems

HW for the weekend (Galileos and Einsteins) or Monday night (Newtons):  Horizontal Projectile Motion Problems.  This is your first assignment of Q2!  Don't forget, test coming up on Friday the 7th.

Projectile (aka 2-dimensional) motion

HW is reading in The Physics Classroom.  Read over the following four sections.  The third and fourth section review what we did in class today.  Due Friday for Galileos/Einsteins, Monday for Newtons.

Go to The Physics Classroom, Tutorial, Vectors-Motion and Forces in Two Dimensions, and read lessons 2a-2d.  Again, this should look familiar based on what we did in class.

This is just a screen shot- it isn't a link.

Free Fall, Up and Down Problems

HW tonight (Tuesday for Galileos/Einsteins, Wednesday for Newtons) is called "Fay Wray problems."  There's actually only one about Fay Wray, but its a more imaginative title than "More Free Fall problems."  Here's a photo reference:

There she is- teeny tiny in King Kong's hand.  Anyway, free fall.

These problems are CHALLENGING.  That doesn't mean you can't do them- you can.  Make a list.  For several of the problems you need to use one equation to find the time, then plug the time into a second equation.  Do stay neat and organized as you solve the problems.

Monday Night

No new HW tonight...instead I would like you to go through Aspen and check to see if you are missing anything (NTI = Not Turned In = 0).  Turn any missing work into your folder.  Remember, the quarter closes Friday- no late HW accepted after then!

Your dog can't eat your iPad homework...so guess that means you have no excuses, right?  RIGHT?!?!?

Graphing Quiz, Take 2

If you got less than 80% (less than 18.5/23) on the quiz you can do a retake up to 80%.  This will be in class on Monday.  To review:

1.  Look over the chart of notes we did in Notability called "More graphing hints."  Look at your quiz with these notes to make corrections.

2.  Open a clean copy of "Graph Sketching HW" into Notability and complete it again.  Check your work using the KEY.

3.  Open a clean copy of "Describe the Graph" into Notability and complete it (this was not originally assigned but there as a resource).  Check your work using the KEY.

Free Fall: How far has it fallen?

Galileos and Einsteins: Monday night HW is "Free Fall Displacement and Velocity Problems."  Newtons you will do this Tuesday night.  Due Wed for everyone.

Free fall practice problems

HW over the weekend for all sections:  "Velocity and g problems" found in the folder.

Have a good weekend!

HW after the quiz

Reading and notes in the Physics Classroom:

Introduction to Free Fall:  What does "free fall" mean?  Does this motion show constant velocity or acceleration?

Acceleration due to Gravity:  What is the symbol and value for acceleration due to gravity on earth?  What is the initial velocity for a dropped object?  What is it's final velocity after 1s? after 2s? after 5s?

Make a new folder in Notability called Free Fall for any notes that you take.

Weekend HW

Happy long weekend!  Your HW is to do "Graph Sketching HW," located in the folder.  Use the graphing hints we discussed in class.

Looking ahead, you will have a quiz coming up on the following topics:

1. Reading d vs t, v vs t and a vs t graphs
2. Sketching d vs t, v vs t and a vs t graphs
3. Solving problems using a = vf-vi/t

That quiz will be on Wednesday for Galileos and Einsteins, Thursday for Newtons.

The Physics Classroom reading and notes

The sections are on different HW assignments because of the missed day last week.  Please check your assignment carefully.

Galileos and Einsteins: your HW is to finish the Cars on a Ramp lab, including the two graphs and questions.  That is due Wednesday.  What is described below will be your HW for Wednesday night (due Thursday).

Wednesday night: Galileos and Einsteins are doing the reading below.  Newtons should review the information and make sure they are familiar with the terms listed below.

HW is to read two sections in the Physics Classroom.  Go to Physics Tutorial, 1-D Kinematics, and read sections 1d and 1e (both in Lesson 1, they are 1d Speed and Velocity and 1e Acceleration).  During the reading, pay attention to the following:

• the difference between calculating speed and calculating velocity
• the definition of average velocity
• the difference between average velocity and instantaneous velocity (it describe average speed and instantaneous speed but its basically the same thing)
• the definition of acceleration
• the equation to calculate acceleration
• the units for acceleration

Go to this post to see how to make a PDF from the webpages.

Cars on a Ramp

If you did Cars on a Ramp today (Galileos and Einsteins Monday, due Wednesday, Newtons TBD), your HW is to finish the lab packet including the two graphs and the questions.

Displacement vs time and velocity vs time graphs

Thursday will be Day 3.  Friday will be Day 5.  

If today you did the Graph Matching (Galileos and Einsteins Wednesday, Newtons Thursday Galileos and Einsteins Thursday, Newtons Friday) your HW is to do the "Reading Motion Graphs HW."  Use the chart of notes we took in class today.  When you are finished turn this into your Drive folder.  Due Monday for everyone.

Motion.

HW after the test

Your HW for tonight is in the shared folder, in a new sub-folder called "Graphs and x acceleration" (which refers to horizontal, or x acceleration).  When you import this into Notability, make a new folder called "Graphs and x acceleration."  Organizing is awesome!!

Homework, Practice and Test Review Wrap-Up

Here's the deal:

Check that work is turned in to your Drive folder (the one with your name and section).  No missing work will be accepted after the test!

Make sure you know how to do sine and cosine on your calculator.

Complete "Resolving Vectors Practice."  Turn it into your shared folder.  I'll give you points for this.

Complete "Assessment 1 Study Guide." The answer key will be shared in the folder on Friday evening.   The answer key is now in the shared folder. I accidentally missed a few pages of the key when I scanned it in.  They are there now in a separate document (KEY missing pages).  

You don't get points for this (so you don't need to turn it in), but this is your chance to check your progress.  If you are confused after checking the answer key, first try working with a classmate.  Next, ask me in class on Monday (or come find me for extra help).

Extra help Thursday X and Thursday, Friday and Monday after school.

Test Tuesday.

Drawing triangles HW

If you did the work with angles today (Newtons on Monday, Galileos and Einsteins on Tuesday) your HW is drawing and labeling triangles, found in the Linear Motion folder.

Remember, draw the vector counter-clockwise from due East (also called positive x).  Label the hypotenuse, the opposite and the adjacent sides.  Indicate as well which is the x-component and which is the y.

There are also practice slope and vector-adding problems.  Newtons- I just added these this morning.  Please go check the file in the folder and complete the additional problems.

Homework

Next HW assignment...

If you did the distance to the front door calculation today (Newtons on Friday, Galileos and Einsteins on Monday) your HW tonight is "Calculating Slope Practice Problems."  Why are we going back to this?  Because its always good to go back and practice old skills, especially after not doing them for a few days.  That's how you remember them!

So.  The sheet is in the shared folder; complete and turn into your named folder for HW.  Newtons due Monday; Galileos and Einsteins due Tuesday.

Vector Addition

If you used vectors to find the diagonal of the classroom today, your HW is vector addition (found in shard folder). Import into Notability, complete and stick back in the folder with your name on it.

Link to the Phet site for practicing vectors (only works on laptops or desktops, not on iPads):

Phet Vector Addition

Newtons, due Friday; Galileos and Einsteins due on Monday.

More graphing practice

Homework is Graphing Practice HW, in the shared folder.  You may want to make the graph on graph paper, rather than Notability.  Take a sheet from the classroom or print out the graph paper from the document.

Newtons, this is assigned Tuesday night, due Wednesday.

Galileos and Einsteins, this is assigned Wednesday night, due Thursday.

Reading the "Textbook"

Newtons- this is your HW for the weekend; Galileos and Einsteins will do this Monday night.

Your assignment is to read from the textbook about scalar and vector quantities.  The book is the online source "The Physics Classroom" (link in upper right of this blog).  I strongly recommend converting each page into a PDF and importing it into Notability.  This will help in two ways: the pages will be available in your files even when you aren't on wifi; and you can underline, highlight and otherwise mark-up the pages in Notability.  You will get much more out of the reading if you take notes on it.

Follow this link to see a video on using PrintFriendly.com to make a PDF and bring it into Notability.  You'll need to do this once for each of the two pages you are reading for HW tonight.  Those pages are within Physics Tutorial, 1-D Kinematics, lessons 1b and 1c (you can read 1a as well if you like).

AFTER reading those, go to Physics Interactives from the menu on the left, click on Visit 1D Kinematics Interactives, and do all three Vector Walk activities (bottom of the page).

Graphs of Motion

Graphs are a visual way to present information.  It isn't easy to make graph, but it is easy to read them.  If you made a graph today in class you are pretty much done with that part.  However, lots of graph-reading to come.

Look at the two pictures below.  Which one lets you instantly see if tomorrow will be warmer or cooler than today?

The information in both pictures is the same, but the graph shows you the temperature trend.

See?  Graphs are useful.

Over the next several lessons we will be reading graphs that tell us about an object's motion.  If you did the bowling ball today, your HW tonight is "Speed Segment Graph HW" in the Linear Motion shared folder.  Your task is to look at each segment of the graph (A, B, C, D and E) and to find the speed during that time, as well as the distance traveled.  (There are also a few conversion practice problems thrown in).

How do you find the speed?  Use slope. The formula is there.  You'll see that when you find the change in y over the change in x and you include units, you'll end up with a unit of speed.  Use the information on the y-axis to find the distance traveled.  When you have an answer stop and ask yourself if it make sense.

Turn this into the Drive folder with your name when done.  Newtons, due Friday; Galileos and Einsteins due Monday.

Speed

I feel the need....the need for speed

If you did the marble lab today, HW is Speed Practice problems, found in the Linear Motion folder.  You should show all your work and give answers with units.

Turn in the work to your folder when complete.  Due Thursday for Newtons, Friday for Galileos and Einsteins.

Completing your HW electronically

Here's how to do it:

1.  Find the HW "More Unit Conversion Practice" in the shared folder (within General Info).

2.  The copy in there is view-only, so you will need to either make a copy for yourself that you can save in your own Drive (for example, in the folder you shared with me) or in Notability.  I suggest using Notability since you can write on it just like paper.

3. Click on the three dots in the upper right.  Next choose "Share & Export," then "Send a copy."  For format choose PDF and hit OK.  Next, choose "Open In Notability."

4.  Create a new note in Notability.  From here you can use the pencil tool to write on the sheet.

5.  Once you are done with your HW, while you are still in the note, click on the share box ("sharrow") in the upper left.  Choose Google Drive, then find your folder that you shared with me in destination.  Click on the blue link at the top that says "Export to Turner Henry Physics (or whatever your folder is called :)), then "send to google now."

All done in five easy steps!!  If the steps seem overwhelming, trust me that you will get used to it and it will seem super easy soon.  Still confused? Here, look at this calming landscape:

Ok.

You can also print and turn it in on paper if you want.  Paper is always ok.

And...don't forget to check the list in the first post to be sure you have completed all your housekeeping tasks.  Thank you!

Welcome!

Things are going to be a little crazy to start off, especially with getting everyone's iPads set up.

Just do your best and get done what you can.  No worries if you are having iPad problems- we'll deal with it in class.
