For those of you who missed the amazing, awesome oppurtunity to see the cancer/radiation therapy treatment center,

 

SUCKS FOR YOU, YOU NEED TO PRIORITIZE   that's really too bad :( 

 

It was fun :D

 

Luckily, Mina we took some photos..............

 

enjoy.

Welcome to the SJAM 4U Physics wiki!

 

April 29, 2011

Last day for me. Today we built ferrofluids using a combination of iron filings and oil. Some of you were ambitious enough to try other solutions, such as water or soap. As promised, I will share a few other recipes for ferrofluids that you can make at home. This one looks good but involves some nasty chemicals and fumes so be careful. This one looks good and cheap, but requires that you destroy some old VHS tapes. Don't break the one of your parents' wedding. Finally, this Popular Science article explains a few options for making ferrofluids, including using some crazy French nail polish.

 

April 27, 2011

Today we did a shortish lesson on electromagnetic induction and watched Mr. Brichta make smoke come out of a couple of coils. Then Mr. Zehr got in there and blew them up. The unit test is tomorrow, so study hard. 

 

April 26, 2011

Today we watched the last bit of the TRIUMF videos. I have added links to the videos on the Fields Unit page so that you can watch them at your convenience and try out the problems at home (note that they are on Youtube). Some of you have been asking me to post scanned solutions to the worksheets. While I have worked through the problems, I think it would be a bad idea for me to post solution without you having a chance to try them. Try the problems first and talk to me if you can't get anywhere. Also, I have added the final worksheet to the Fields Unit page.

 

April 21, 2011

Today we built cheap-o motors. Some motors were cheaper than others. We also learned that the left-hand rule also applies to the motor force, so long as we remember that it is electrons that are responsible for current. I did a small PowerPoint and I handed out a worksheet to help you consolidate ideas from the second half of the electric fields unit. I've also added the worksheets to the Fields Unit page. 

 

April 20, 2011

Today we continued the discussion of the LHR and the RHR and formalized where the magnetic force equation came from. We talked about Tesla and solved a problem together. Here is the PowerPoint from today.

 

April 19, 2011

Today we did some work using the left-hand rule (LHR) as it applies to different situations. We investigated the operation of a cathode ray tube (CRT) as an example of how magnetic fields can exert a force on moving charges. Remember to read section 8.2 to review some of the things I talked about in class.

 

April 18, 2011

I talked about the speaker activity and began the introduction to Natural Magnetism and Electromagnetism. Here is the presentation I gave today in PowerPoint format.

 

April 16, 2011

You guys did some great work yesterday! The speaker project was a resounding (emphasis on sounding) success. If you have a moment, think about the operation of the speaker that you built. You had a coil interacting with a magnet to move a Styrofoam plate. How does that work? Also, for you future engineers, how might you improve the design of the speaker? Keep in mind the cost of the speaker you built was less than $2.

 

April 13, 2011

Here are the answers to the questions from the Electric Fields Worksheet. The answers to the textbook problems are in the textbook.

 

1.       An object charged by contact must be touched by the source of the charge. An object charged by induction is not touched by the source object.

2.       1.6 x 10-9 N.

3.       0.085 N [away from the 1.3 x 10-6 C charge].

4.       Typo: q1 must be 15 x 10-6 C. In this configuration, the negative charge is 0.775 m from the smaller positive charge.

5.       4.4 x 10-8 C. We do not have enough information to know if this is positive or negative.

6.       2.7 x 1011 electrons on each sphere.

7.       The electron and proton will experience forces equal in magnitude but opposite in direction. Although the forces will be identical in magnitude, the electron will have a greater acceleration since it has 1/1000th the mass of a proton.

8.       3.2 x 10-15 N along the positive x-axis.

9.       7.2 x 105 N/C [down].

10.     2.7 x 105 N/C [N 23 degrees E]. (Fixed this April 13)

 

April 11, 2011

I've created wiki pages for all of you to write your wikis in. The easiest way to get there is to find your group near the bottom of the wiki assignment page and start writing! Remember, they are due on April 21 at noon! You've got ten days to come up with something magical.

 

April 6, 2011

Your homework for this evening is to read section 7.5 on the notes page, or read the relevant section in your textbook. It will be the topic of tomorrow's in-class lab, which is due at the end of class! There is also a conceptual question on Mr. Vrolyk's blog that you should answer. Finally, you should be ready to provide me with your wiki topic tomorrow. 

 

April 5, 2011

I have added a page that includes all of my notes in PDF format. Due to time constraints, I do not cover everything in the notes in class. Feel free to download these to assist with studying and concept reinforcement. In particular, all of the problems that I do in class are in the notes--as well as a few extra that might be good on a test. Yep, that was a hint. 

 

March 30, 2011

Link for group wikis, including rubric and Mr. Brichta's ideas for projects.

 


 

I am new at wiki's so bear with me - and my hope is that you students will take over this thing.

If someone wants to post the class documents here - and possibly you could start sharing your answers with each other (my worksheets don't have answers on them).

For the homework question do we assume equal mass?

David Vrolyk said

at 9:55 am on Feb 15, 2011

Shane! I am 6 foot 5 inches of solid muscle!
Do you think my wife has the same mass as me!

The fact that you asked the question shows that you are thinking and get the concept - well done.

Nancy Xiao said

So it was assumed that friction existed?

"An example of the 'fictitious' [centrifugal] force is seen in a ball that steadily drops at a constant rate parallel to the axis of rotation. From a stationary frame of reference it moves in a straight line, but from the rotating frame it moves in a spiral. Because the projected horizontal motion in the rotating frame is a circular motion, the ball's motion requires an inward centripetal force, provided in this case by a fictitious force that produces the apparent spiral motion."
-Wikipedia
And Mr.Vrolyk said that centrifugal forces didnt exist :O

I was away for the last two days of the lab, and just got back today. Would anyone be able to send me their data for the lab? I'm missing a few values.

Stanley said

Mr.B do you have all the answers to the hmk questions?

J.-P. Brichta said

at 9:40 am on Apr 12, 2011

Well, if I don't I can work them out. :)

Natila said

at 3:10 pm on Apr 13, 2011

could you please put up full solutions? thanks

Natila said

at 4:19 pm on Apr 13, 2011

Could ANYONE post the solutions as they finish this? like FULL solutions! Please!

ShaneWilton said

When we make a word problem for the wiki assignment, does it have to be something that other people in the class are expected to be able to solve? I'm looking at the equations relating to superconductivity, and from what I've seen, it's all partial differential equations. Is it fine if I make the word problem deal with regular conductors using Ohm's Law or something?

J.-P. Brichta said

at 3:54 pm on Apr 18, 2011

Yes, that's fine Shane. I don't know how you can make a question about superconductors without knowing about Maxwell's equations.

Amelia said

The date is wrong.-Shan=

J.-P. Brichta said

Muhammad Khalid said

at 5:14 pm on Apr 19, 2011

and lets say somebody (not me) wanted to add a video, how would said person add this video?

Muhammad Khalid said

at 6:19 pm on Apr 19, 2011

never mind i have solved this problem as well, thanks for all the replies.

Natila said

at 9:33 pm on Apr 19, 2011

this is nura, lol, even though it says natila. just wanted to point out, i diidnt fugure out the wiki account yet :(

J.-P. Brichta said

at 7:28 am on Apr 20, 2011

Nura, see Mr. Vrolyk ASAP. I can't help you get access, unfortunately.

Natila said

Hey Mr. B!
Is the test on wednesday or thursday?

Ryan Tomas said

at 10:38 pm on Apr 25, 2011

He said Thursday.

clairehiggs said

at 9:18 pm on Apr 26, 2011

Thanks!

ShaneWilton said

at 6:39 pm on Apr 25, 2011

I'm pretty sure he said Thursday.

J.-P. Brichta said

at 10:20 am on Apr 26, 2011

He definitely said Thursday.

Here's the program I mentioned: http://universesandbox.com/

There's a commercial version and a free version, but they are nearly identical.

Arne Huang said

– Percent difference

Arne Huang said

We cant use the conservation of momentum and kinetic energy to verify conservation of momentum and kinetic energy right?

WOW WHAT AWESOME PHOTOS. I WONDER WHO DID THAT HOW NICE OF THEM.
