Magnetism

Today class was fun, I think . haha just kidding.  Well, first thing we did were the corrections for our last test.  Afterwards we went over the two worksheets we got yesterday which were the magnetism sheet and the study guide, "24.1 magnets: permanent and temporary".  Once we were done those we were given 2 more sheets which were the magnetic fields, the earth's magnetic field and a booklet, 2.3 Ferromagnetism and the Domain Theory of Magnetism.  In the booklet, we did questions 1-4 together.  If you want them, they should be here somewhere on the front page.

If you do not have any of these sheets yet, you should get them as soon as possible. (=

P.S. Do not forget to ask Ms. Kozoriz for your exam review sheets.  This will help you a lot when it comes to your exam!

Gravitational Fields

The day begins with the looking over of the Chapter 5 worksheet. Students were requested to answer one of the 12 questions on the white board.

Chapter 5 Review
1. 0.29 m/s^2
2. 5 kg
3. 22 x 10^
4. 145 N
5. -0.53 m/s^2

*note: During class I was preoccupied with trying to create an account for this blogger and did not notice the answers following question 5 were written on the back end of the classroom. I do not trust my own answers to post it here.

After answering and correcting the Chapter 5 Review, we were given the Electrical Field/Lines booklet and Chapter 21 Study Guide.

That is all.
Next scribe will be chosen in class tomorrow.

Gravitational Fields

Today in class we went over the Falling and Air Resistance sheets that we were given yesterday.

Here are the answers to the Bronco skydives sheet:

Circle the correct answers.

1) Most

2) a,b

3) d,e

4) still downwards

5) c,f

6) c,f

7) c

8) greater

a) a= 10 m/s²=

b) a= 6 m/s²

c) a = 0 m/s²

d) a = -2 m/s²

e) a = -10 m/s²

f) a = 0 m/s²

Here are the answers to the second sheet we were given. It's the sheet with the 7 problems.

1) Air resistance is equal to weight.

2) Air resistance to weight ratio is less for the skydiver.
Increase the surface area to make both terminal speeds equal.

3) Fnet = 25 N
Fnet = 10 N [ down ]
Fnet = 0 N

4) 100 N

5) As a skydiver falls faster and faster through the air, the net force decreases.
Acceleration decreases.
Reason: As she is falling through the air, there is an increase in air resistance.

6) She gains more speed in the first second of fall.
She gains more distance in the ninth second of fall.

7) We used the following free body diagram to answer this question.

After correcting the sheets we were given a hand out on Static Friction. We went over this hand out and were given out two review packages. If you weren't here today you should go see Ms. Kozoriz to get these sheets.

That was basically it for today's class.

May 25 2009

Today in class we went over the two sheets ms.k gave to us on friday. One of the sheets answers are below this blog. The other sheet we did on the white boards. You will have to see someone in class for the answers for that sheet. today Ms.K gave us two more worksheets, she asked that they are to be finished for tomorrow's class so we can correct both of them in class. That's all we did today. Oh i forgot question 9 and 10 on the second sheet had to be handed in today. So that's it!!!!!!

gravitational fields

hey everyone!


The Gravitational Field
A field is something that has a magnitude and a direction at every point in space. Gravity is a good example - we know there is an acceleration due to gravity of about 9.8 m/s2 down at every point in the room. Another way of saying this is that the magnitude of the Earth's gravitational field is 9.8 m/s2 down at all points in this room.
Gravitational field: g = F/m
where F is the force of gravity.

gravitational field

hey everyone 

in today's class we did a lab on gravitational field. Mrs.K handed back our labs and our assignment on Force-Vector Diagram. Mrs. K didn't  go over the assignment that she handed back. But the beginning of the class we did weight and the formula of the weight is f=mg, f=mg+ma and f=mg_ma. my advice to all of you is that if you want to be successful in this world, always to kind and generous to everyone. thank you.

Force Vectors

I'm really sorry for posting late. First of all I came late in the class. I think Mrs.K handed out WORKSHEET: NEWTON’S LAWS OF MOTION and THE PRACTICE: FORCE VECTORS ASSIGNMENT. We went over THE PRACTICE:FORCE VECTORS, it was #1-3 but we omit #2&3. If you didn’t correct THE PRACTICE: FORCE VECTORS please check the slide that Ms. Kozoriz putted up for me. I forget to say that we handed in the FORCE-VECTORS DIAGRAMS it was due today.

I don’t really know if this is our homework, but it looks like

Free-body diagram

hey

 at the beginnig of today's class Mrs.K asked us to hand in our labs for thoseof us  who didn't finished it yesterday. after that Mrs.K  handed out some work sheets on free-body diagrams. Free-body diagram is a diagram that represents an object and all the forces acting on it. and one important thing to always remember is

• draw a sketch of the object completely removed from its physical surroundings. often the force vectors are drawn from a dot at the centre of the object.
• draw vectors representing the force acting on the object.
• do not include forces exerted on the surrounding by the object.
• when finding the net force acting on a object from a free-body diagram, use the rules for the vector addition.
  

Force of gravity is a long-range force due to gravitational attraction between two objects, generally Earth and an object.

Force of thrust is when a general term for the force that move onjects such as rockets, planes, cars and people.

Force of tension is when the pull exerted by a string rope, or cable are attached to a body and pulled taut.

Force of spring is when a restoring force , that is, the push or pull a spring exert on and object.

Normal Force is the contact force exerted by a surface on an object.

Force of friction is the conact force that acts to oppose sliding motion between surfaces.

don't forget that we have homework and is due tomorrow.

FRIDAY MAY 1st ***LATE

On friday Mrs K handed out two work sheets and chapter 4 study guide and we basically did work throughout the whole class. I'll provide more info on the worksheets tomorrow because I forgot my binder in my locker. SORRY BLOG HEADS!

Vector Ideas

So today Ms. K was not here. In class, we just finished up the Minilab that we recieved on Monday and worked on it today and yesterday. That Minilab is supposed to be handed in today but the sub let us hand it in tomorrow. Also, the sub gave us hand out a book on vectors. All you need to read is the first 2 pages and do the questions on page 3 and 4. See you all tomorrow.

TUESDAY, APRIL 28

Bonjour fellow physicians!!!
Today, Ms. Kozoriz is back!
We corrected the booklet (Appendix 3.8) that was given on Thursday.
The answers are uploaded.
Finally for the last twenty minutes of class, we started with another booklet, that was handed out yesterday by Ms Hall. We went through the first few questions. Please try to finish the booklet by tomorrow when we correct the whole thing.

One Dimension Motion

last thursday ms K went over the fill in the blanks 'study guide worksheet': 3.2. If you missed the class or didnt get the answer for any of the blanks, here they are:

POSITIVE AND NEGATIVE VELOCITIES:
positive, negative, positive
right, left
magnitude or size
positive, negative

INSTANTANEOUS VELOCITY
straight
tangent
slope

VELOCITY-TIME GRAPHS
time, velocity
straight, parallel
positive
negative, vertical
displacement
position, position

RELATIVITY OF VELOCITY

positive, speed of light
the same, Eintein's

ms K also explained to us the relationships between graphs and velocity (can be found in the slideshow below)

after that, she gave us an ifo sheet, CONSTANT VELOCITY, and some practice sheets: MOTION: INTERPRETING POSITION-TIME GRAPHS and GRAPHING MOTION IN ONE DIRECTION.

April 15, 2009

Hey guys,

In today's class we read pages 12-16 and filled in the supporting and counter argument columns on the wave model of light hand-out. We then answered questions 9-12 in The Nature of Light: Part 2 booklet. The answers to these questions and the previous sheet have been uploaded to the blog. Next, we read the information on Young's experiment starting on page 17 to page 20. For the remainder of class we worked on questions 1&2 on the Young's Experiment Problems sheet given to us today. These questions are due tomorrow!

I think I might have screwed up the order in which we did things. I apologize! I have a terrible memory. However, I am positive that this was all we did. Please correct me if I'm wrong.

**Our test on this unit will be on Monday or Tuesday of next week.

april 9, 2009

Today in physics we corrected our test from last unit and all the answers should be or are on the blog.  Afterward, we were given a worksheet, which was a chart for evaluating the models of light.  If you don't have the sheet yet, you should get it right away from Mrs. Kozoriz.  So on the sheet we learned the meanings of:

rectilinear propagation: travel in straight lines

reflection: just look into a mirror

refraction: the bending of a particle entering a new medium

dispersion: light is refracted to form colours of the spectrum

diffraction: the bending of a wave around a barrier or through an opening

partial reflection/refraction

And speed of light .. again.

For each of these phenomenon we came up with supporting arguments and counter-arguments.  All of this information should be on the blogger as well.

Lastly, we were given the Part 2 Wave and Particle Models of Light Problems booklet.  We were assigned to do questions 1, 3 and 4.  They shouldn't be that difficult .. i think.  And that's pretty much it!  :D

Scribe for Monday is Jenn

Nature of Light Part 2

Today in class we read pages 2 - 7 on our new booklet, called "Nature of Light: Part 2 The Wave and Particle Models of Light" Ms. K gave us a worksheet to work on, about the four theories of Light or something like that. Answers are below, this rather short post of mine. 

The next scribe? I don't know, whoever didn't do it yet I guess. 

hah! i finally did a blog! =P

OK! so, i finally remembered to do the blog, which is pretty amazing if you ask me =O
anywho, today we went over some questions. i dont know what sheet they were from cause i kinda wasnt paying attention because i was sooooo tired and cranky. But after those questions i paid attention to the graphs we worked on and the fact that we have a test tomorrow, Whooppy!
So for the test you gotta know the whole booklet on nature of light, or something like that. and understand how to find the slope of the graph and the formula used to express it.
I really dont know what else to write, im completely brain dead today due to the lack of sleep.
and i think Anna should scribe for tomorrow...i DO get to pick the next scribe right?

Nature of Light

March 25 , 2009

Today in class we started off by finishing our lab worksheets we did on Monday and catching up on any work that we didn't complete. If you missed any classes, please see Ms.K and ask for any work that you missed.

If you were caught up with all the work Ms.K provided us with 3 worksheets. They included a Crossword Puzzle, Graphing Data Study Guide and a Graphing question sheet. Answer these questions by reading in the textbook.

Remember, spring break is coming up soon so dont get to lazy! You should review these worksheets or complete any incompleted work! And ask questions if need. Have an awesome spring breakkkk!
Renee to scribe for Thursday

Nature of Light

Monday, March 23/2009

Hey guys!

We started today's class by going over Exercise 1 and Exercise 2 of the Grade 11 Physics: Nature of Light: Part 1 sheet, handed out last friday. Then we briefly looked at pages 8-10 in our Nature of Light booklets before doing a "super-fun" lab; as stated by Ms. K.

We were instructed to determine the diameter and circumference of 5-8 different lids, and then graph the data onto graph paper. We then used our results to answer the required questions. This lab should be completed and ready to hand in tomorrow! (Don't forget to label both axis and give your graph a title.)

There will most likely be a test on this unit after spring break, so make sure that you ask someone for help if don't understand something. How about Friday for the test?????

*Outstanding Concept maps are to be handed in IMMEDIATELY, if Ms.K will still accept them.

Next scribe is: whoever hasn't done it yet.I think Jon wanted to do it.
