Today we...

had a substitute teacher! Somehow Ms. K just disappeared without a trace. We never even got a review for our test tomorrow, but c'est la vie. haha I think that's correct, don't mind my horrible french.

So what did we do? Not much. I think we all worked on some homework for a certain amount of time during the class.

We were to go over questions from the green book. They were on page 237 and we had to do questions, 1, 3, 6, 9, 10, 12, 14, 21, and 23. I think some of us did it, but we had no answer key to check off of and thus who's to say that we were right?

That was pretty much all that happened during our uneventful class. We have a test tomorrow so I think people should read up on centripetal force and learn how to use the formulas given in the previous post. Hopefully we'll all do well on the test. Good luck everyone!

Thursday April 17

Hello fellow physics people. No one scribed for the class on thursday so I'm taking the time to do it now. Actually it's quite a blur it was afterall, such a long time ago.

So I think we went over a few sheets like the momentum and energy one with Bronco Brown. Then we went oer the study guide about Energy and Work. Then somewhere in there I think we went over questions from the green book. They were on page 213 and we had to do questions 1, 3, 5, 8, 10, 12, 17, 22, and 23.

Some equations to remember are:

Ek = (1/2)mv^2
Ep = mgh
W = fdcos(theta)
Fs = kx

That's all I think. Like I said, it's a blur.

wednesday, april 16

since no one really finished their labs, we worked on it today. It took longer than expected so that was all we basically got to do.

tuesday april 15

Okay so today in class we went over the back page of the chapter 11 study guide. After, we read the last page of the booklet with all the notes. The last thing we did was a lab (Hooke's Law) which is due tomorrow.

for monday, april 14 / 08

Today (i mean yesterday) we went over the first side of the chapter 11 study guide . If you need the answers to the blank spaces, I am pretty sure anyone from class can happily help you with filling them in. We were then assigned to finish the back side of the sheet. We were also supposed to complete Energy and Work worksheet and the Momentum and Energy Worksheet. And that is about it !

Monday, April 7

On the first day back from spring break we did a lab on circular motion. We had to attach washers to the end of the string and record the amount of time it took for 30 revolutions/swings. The radius was constant at 0.8 meters and allowed us to calculate velocity. Theeenn we graphed force vs. speed and force vs. speed². There were some questions to answer in the lab and that was basically Monday's class.

Next to scribe is DUONG!
