MONDAY : JANUARY 10 , 2011

Today, we started off the class with Ms. Kozoriz handing out our test corrections and some work assignments that we gave in awhile ago.

We also got our EXAM REVIEW BOOKLET too, so those who were not in class today, make sure you get them soon to start studying!

Next, the Electric Circuit booklet that we were supposed to make as a "self-review" for our exams were due today and asked to be handed in. If you were not able to complete and hand it in today's class, please finish and hand it in as soon as possible for tomorrow's morning.

We went over the corrected Compound Circuits 4) d. question that we were supposed to hand in on Friday's class.

After that, Ms. Kozoriz let us watch this video on Electric Currents and we were supposed to jot down 5-6 points and hand them in by the end of the class. This video was like a review, and for those who didn't finish/start on their Electric Circuit booklet, it could've had some important key points to help you with it.

After the video, Ms. Kozoriz gave us a new worksheet to work on called Combination Circuits.

Again, if you were not in class today, please make you sure you will get the hand-out from her!

Then we had the rest of the class time to work on our Electric Circuit booklet, the Combination Circuits worksheet and review for our TEST on Thursday, January 13.

REMEMBER TO STUDY FOR YOUR TEST ON

THURSDAY, JANUARY 13,

ON ELECTRIC CURRENTS!

REMINDER THAT OUR EXAM IS EXACTLY 3 WEEKS FROM TOMORROW!

Thanks for reading, hope this helped! Have a great night (:

Magnetic Fields, B

HEY GUYS !

For today in class, first up, Ms. Kozoriz start the class off with a short video clip on Milikan's Oil Drop Experiment.

Then we went over the first 4 questions of the worksheet handed out yesterday, called MOVING CHARGES WORKSHEET. [Please see Amy's previous post for the scans if needed!]

The answers are:

After going over the 4 questions of the worksheet, we watched some few more video clips on magnetic fields, magnetism, magnets and 3 videos for each of the right hand rules.

We then received a worksheet called The Path of a Charged Particle in a Magnetic Field. We were given some time to work on it class, and went over it together after.

Last but not least, we were asked to do questions 8-11 on the Moving Charges Worksheet for tomorrow and we will be going over those questions in class !

Thanks for reading and have a good night ! (:

THURSDAY, NOVEMBER 04, 2010

Today in Physics class, we started off by getting back our Conservation of Energy lab and went through it quickly. Then we were given out 3 worksheets, and reminded to hand in our Power Lab if we have not done so [WHICH IS OVERDUE!] and the lab that we did on Wednesday, regarding the spring and weights [please see previous post to regard about the lab].

The three worksheets provided was the Chapter 11 Transparency 11-1, Chapter 11 Transparency 11-2, and Work and Energy: Springs. We were to complete them so that we could go over them on Friday.

Ms. Kozoriz then gave us the rest of the period to work on our labs and the worksheets.

Have an awesome day (:

FRIDAY, SEPTEMBER 10, 2010

For the start of the class, we went over one of the worksheets that was given out the yesterday that didn't have the answers.

[Please see Amy's post for the original sheet].

We worked it out and put all the answers on the white boards.

I've recorded down the answer for those who missed the class or missed an answer and would like to check it over:

We then received another worksheet, but this time instead of working it at home, we worked it together as a class with Mrs. Kozoriz on the SmartBoard.

The sheet that was given out:

Answers to the following worksheet:

Here, we use one of the formulas of finding velocity.

D.B. stands for Donovan Bailey and M.J. stands for Michael Johnson.

Mrs. Kozoriz also asked us how come Michael Johnson ran the 200-m faster than the 400-m. Well, because he had to do both runs! Total of 600-m and of course he would be tired and slow down !

Here, we used the same formula as we used for question one, but we rearranged it so that we could find the distance instead of the velocity.

To change the units of km/h to m/s, we have to divide the number in units of km/h with 3.6 .

** We have to make sure to change the units or else our answer will be wrong ! **

Here we also have to find the distance, but this time we use a different formula to find the distance. This formula uses both the velocity instead of one to find the distance.

Here, we now have acceleration given to us to help us find the final velocity.

Here, we use another formula to find the length of time.

It's also the same formula that we used to find the answer to the previous question, but again, we rearranged it to help find the time instead of the velocity.

What's different here, is that we have a negative acceleration.

Although it's negative, we don't do anything different, so don't let the negative sign throw you off!

For this question, it consists of 2 steps.

First we find the distance using a different formula.

Make sure you use a formula that doesn't use the final velocity to find the distance because we have to find that also.

Here, we assume that the final velocity equals to zero because it slows down to a stop.

Since the time was not given to us in the question, we have to use this formula to help us find the distance instead.

Although question 8 has four parts, we only went over how to do the first one, because once you know how to do the first one, the rest are worked out the same and should be easy to solve.

The worksheet [Gr.12 Physics Acceleration Assignment] that was given out on Wednesday, September 8th had answers given except for question 5. a) & b).

Amy had posted the worksheet and the answers but she didn't have the answers for number 5 because it was given in today's class.

So I'm just reposting the worksheet with the answers for those who might not have seen on Amy's previous post followed by the answers for question 5:

HOMEWORK :

Since we stopped after question 8) a. in class with Mrs. Kozoriz, we're left of to finishing the rest of question 8 to question 11.

She also gave us another handout to work on which is due on Monday, September 20! :

That's all that we did today !

Hope you enjoyed this post. Good luck and see you on Monday ! (:
