Vector Assignment 1-9

Acceleration & Instantaneous velocity

Yesterday, we worked on the following formulas: d=v.t( which is only used for constant velocity) and d=((v1+v2)/2)t which is used when changing velocity, we also worked on instantaneous velocity.
Today, we did the corrections to the vector assignment (which is posted on the blog), and worked on the problems given to us from the physics textbook yesterday. Don't forget about the test on Friday.
Janet can scribe for Thursday.

11 / 26 /07

We didn't really do anything big today, so if you weren't here you have nothing to worry about.
We talked about the difference between constant velocity and changing velocity (acceleration). Make sure you know the difference. We went over Ch.4.1 Study Guide (acceleration).
All we did basically was work on the two acceleration worksheets that we got today. Also the booklet appendix 3.8 was due and don't forget to study for the test on Thursday.

Thursday's Scribe

Thursday's Class .. November 22/07


all we basically did was cover the very last page of the sample problem booklet. Then ms.kozoriz let us (well who ever wanted to use it) the smart board. Which had to do with the motion sensor. She handed us the assignment that is due on MONDAY NOVEMBER 26/07. The assignment is Appendix 3.8: Motion: Interpreting Position-Time Graphs. And had also handed us notes to look over which was Constant Velocity. Thats what we'll be learning next.

Well have a niiice long weekend =)
Monday's scribe is MIKE!

Friday the 16th

On Friday November the 16th, we only had one assignment that took us the whole class to finish, Pirate Treasure Hunt was the assignment. that's pretty much what we did.

Wednesday class...

For today's class, Ms. K gave us the answers in our worksheet-chapter 3: study guide (the back part). Here are the answers:
3.2
Positive and Negative Velocities
  1. postive
  2. negative
  3. positive
  4. right
  5. left
  6. magnitude
  7. positive negative

Instantaneous Velocity

  1. straight
  2. tangent
  3. slope

Velocity-Time Graphs

  1. time
  2. velocity
  3. horizontal
  4. parallel
  5. positive
  6. negative
  7. vertical
  8. displacement
  9. position
  10. position

Then, she gave us another worksheet, mostly, it has a position-time graph. This took most of our time answering it then we went over the answers but I don't think we went over on the very last part. Here's what I've got:

Sample problem


(a) A (b) 750m (c) C (d)
(i) 750m
(ii) 250m
(iii) -750m
(iv) 0

(e) velocity for section A: 5m/s B: 2.5m/s C: 0 D: -3.75m/s

(f) 1500m


Practice (A)

1.   a) .5m/s   b) 0.83m/s    c) 0.6m/s

2 a) 4m b) 3m c) 1m/s

3. a) 160km[N] b) 80km/h[N] c) 0.5h

4 a) 50km/h b) $-1.25/week
c) -.625kg/week d) 50N/m
e) 80kg/m^3 f) -1.5°C/s


That's it for today's class...sorry it's late. Next scribe: Mike???

November 20's Scribe - By Tony Nguyen

Today's class was pretty simple. All we did was correct the Study Guide 4.2 in class. I think Mrs. Kozoriz uploaded some slides about the corrections so go check it out, it'll save me some time typing out answers.

Anyways, Mrs. Kozoriz gave us some answers in our Vectors assignment which is due on November 21, 2007 in class to be handed in.

This is all we did for class basically. :D Thanks for your time classmates.
Scribe for tomorrow is Melissa

Grade 11 Kinematics

boo.. so I AM THE BLOGGER FOR TODAY =( but anyways..

Today in class we reviewed what we learned in grade 10 science about position, distance, time, displacement, speed, and velocity.
Remember that distance, time speed are all scalar quantities.
Position, displacement and velocity are all vector quantities.

We also went over the assignment given to us last class - "KINEMATICS-FRAME OF REFERENCE"
So here are the answers for those who were not in class today...
Problem A
1. +9km
2. -5km
3. +6km
4. +4km
5. -16km
6. +1km
7. 14km [W]
8. 21km[E]

Problem B
1. 9km
2. 5km
3. 6km
4. 20km
5. 16km
6. 11km
7. 14km
8. 21km

We also started another worksheet (CHAPTER 3 - Study Guide) which we never got to finish during class so i believe we will go over it next class.

so that is all! and next scribe will be .. YONAS..
kaaay.. BAHHH! (:
