Hola physics lovers,

Today we had a substitute, Mr. B. We went over the homework in the textbook and worked on a worksheet called Transparency Worksheet and went over it in class.

We got two worksheets called Acceleration and Information in Kinematics Graphs which are due tomorrow, SO DO YOUR HOMEWORK!

and yeah..
test on Friday May 2, yeeeee! :)

Adios amigos, see you all tomorrow!

April 29, 2008 (:

waadaaaaps (: hi guys! oh boy, i miss this site . yeaaah okay anyways, today we didn't really do much..

Oh Canada
Announcements

and then..
Ms. K handed back our lab which was " Motion on an inclined plane " because most of us did the graphing part wrong. So, she gave us time to fix our mistakes. Then later on we corrected the Acceleration and Accelerated motion sheet which was handed out yesterday. So anyways each of us had to do atleast one question on the board AND IT WAS FUN (: yeah.

AND THEN.. oh we have homework/practice questions
on the green textbook page 82 numbers 1, 2, 5, 8, 10, 11, & 16 .
YOU GUYS BETTER DO YOUR HOMEWORK!
.. because i forgot my textbook in my locker = (yeah, sorry Ms. K)

okie doinks, i think that was all for today.
and reminder : test on Friday

au revoir (:

Graphs

Good evening mortals! No one scribed, so Jasmin's gonna do it! Too bad suckas! XD Well... we started off the class by going over "Chapter 4: Study Guide" She then handed out a sheet that said "Constant Velocity" on the side (it's horizontal). She explained what was happening with each graph and how to find different variables. Once she explained that she gave us a booklet that says "Constant Velocity" on the top. That booklet basically explains what she explained. She gave us another sheet called "Acceleration" which consisted of problems dealing with the formulas and we'll be looking over it tomorrow morning.

Today we had a substitute teacher. I was tempted to skip but my conscience (Jasmin) did not allow me to. He had told us to finish up our lab assignments given to us yesterday. When that was completed he handed out two sheets for us to do:

Chapter 4 Study Guide
Chapter 5 Study Guide

Good class. Gotta have more without Kozoris in it. All jokes all jokes =D, thanks for your tissue.

"Motion on an Inclined Plane" Lab

Good evening peeps! Jasmin's in the house! Raise the roof! We started off today's class by correcting the "Sample problem" worksheet. Once we completed that, Ms. K gave us a lab to do called "Investigation 2.1: Motion on an Inclined Plane". It required four bricks, a cart, a ramp, a timer, and ticker tape. The hand out describes what is needed to be done with the information collected. We had the rest of the class to work on it and she's going to give us time tomorrow to work on it. The booklet called "Appendix 3.8 : Motion Interpreting Position-Time Graphs" was due today, but if you didn't complete it, shame on you! Tisk, tisk... Just kidding! =D She's allowing you to hand it in tomorrow. =)

Once again, the next scribe is... Joseph because he was suppose to scribe today, but instead I did it because I'm awesome! =D

Today's class

Today, we received a sheet called "position vs time". We had to figure out which overlay represents a linear relationship and a parabolic relationship. We also had to compare the change in velocity between the two overlays.

Then, we received a new sheet ( sample problem) that we worked on in class. In this sheet, we have to find the velocity , distance and displacement of each question.

Reminder: The appendix 3.8 : motion interpreting position-time graphs booklet is due tomorrow!! It's the 3 pages booklet that we received yesterday!! AND LAST ANNOUNCEMENT, I think we're doing a lab tomorrow!! So don't skip !! =)

hehehehehe =D

Tuesday's class =)

Yesterday, we finished and went over the sheet "chapter 3 study guide".
After that, we received a new sheet called "Appendix 3.8 Motion: Interpreting Position-Time Graphs.

And that's about all that we did yesterday, I think. Well, that's all i can remember !
hehehehe

Good Evening good evening

Exciting day today.

Ms. K brought us new toys to play with today. It was a gadget that could tell how far, and how fast you were going from a point. We were given different line graphs that we were to copy using the technology given to us. There was a position time graph that we had to copy, and a velocity time graph we had to copy.

After we were done she gave us a sheet called "Chapter 3 Study Guide".

That's it for the day. Good class good class.

HELLO FELLOW FRIENDS :)

On Thursday we had our Unit Test: Nature of Light II

Today we got our tests back and started on our new unit called: Kinematics

We covered on these topics Position and Distance, Vectors and Scalars, Time, Position and Displacement, Average Speed and Average Velocity. Which are all found in the booklet that we got yesterday.

Today we got two worksheets, one in class: KINEMATICS-FRAME OF REFERENCE
and one to hand-in on Monday: Appendix 3.6 Describing Motion in Various Ways

*NOTE: Appendix 3.6 Describing Motion in Various Ways is DUE MONDAY !

Have a wonderful fun-filled weekend everyone :D

Physics 30S April 15, 2008

Today in class we learned how the properties of light interact with photocells and the Photoelectric effect. We learned how different light frequencies and different threshold frequencies, and the type of cathode metal affects the current of the photocell. We also went over how both the Wave theory and Corpuscular theory could be used and when they can be used when studying the properties of light.

April 14 2008

Good evening good evening

Today we started off quite quickly. We worked on a pink sheet called Chart for Evaluating the Models of Light where we would prove or disprove different theories.

We read many topics in our booklet as well including:

4.2 Early Attempts to Produce and Interference Pattern in Light
4.3 Young's Experiment
4.4 Young's Experiment: Interference at Three Angles
4.5 Young's Experiment and Deriving a Useful Equation

Once our reading was completed we continued to do an experiment. We took a ring stand with a clamp and clamped a meter stick right in the middle. Below the meter stick we placed a lamp, and we covered it with different colored films, then we took 2 slides that had a little slit that you could look through. We distanced ourselves 2 meters away from the meter stick and looked through the slit, and we found out how many nodal lines there were in 10 centimeters

And that's about it!
The next scribe shall be: Dana!

Wave Theory of Light

Good evening humans! Jasmin's up in here and I am once again the scribe. On Friday we started the class off by reading the section 'Wave Theory of Light' in the pink booklet. We read all the sections in that section. We noticed that a lot of things in that section are similar to the 'Waves' unit. Such things like reflection, refraction, and diffraction. She then gave us a pink sheet entitled 'Chart for Evaluating the Models of Light'. We did a similar sheet for 'Newton's Particle Theory' and our task was to do the same for the 'Wave Theory of Light'. That's what went down during Friday's class.

Next scribe is.... Joseph again because he told me to pick him! =D

april 10 2008 george

The first thing we did in class was correct the sheet she gave us named appendix 2.4: Chart for Evaluating the Models of Light and then whe went on to the Nature of Light part 2 booklet and read from page 8 to page 11, we read 2.0 Determining the Speed of Light until 2.4 Measuring the Speed of Light:Michelson. After reading, she gave us a sheet called BLM 2.10 Contribution to the Determination of the Speed of LIght for homework. and thats it :D

Wednesday April 9 2008

Today was a remarkable day (weather-wise). We read 1.6 Newton's Corpuscular Theory and Dispersion, and 1.7 Difficulties with Newton's Corpuscular Theory.

1.6 Newton's Corpuscular Theory

Dispersion - When white light passes through a prism, the light is refracted by different amounts, and the colors of the spectrum result

1.7 Difficulties with Newton's Corpuscular Theory
When light refracts, some of the light is reflected. newton had difficulty explaining the phenomenon of partial refraction, and partial reflection.

We were then given a sheet of different phenomena's, and were to explain supporting arguments, and counter arguments of the phenomena.

A surprise bus ridership was announced, thus cutting our class time by like 30 seconds. Bus ridership went quick.

That was basically it for that class so I guess the next scribe shall be:

Daureen wohoo!

Nature of Light: Newton's Theories

Good evening peoples! It's Jasmin up in the HIZZ HOUSE!!!

In class we read the following from the pink booklet:

1.3 Newton's Corpuscular Theory and Rectilinear
1.4 Newton's Corpuscular Theory and Reflection
1.5 Newton's Corpuscular Theory and Refraction

So we basically talking about Newton's corpuscular theories (obviously). After reading all that, Mrs. K gave us a hand out entitled "Newton's Particle Model for the Refraction of Light" which required us to do a lab. Our task was to measure the angle of incidence and angle of refraction for three angles to the right of the normal (the 90˚ mark on the wood) and three angles to the left. We would then have to record it and then solve for the index of refraction (your answers should all be the same if you did it correctly).

It was kinda funny how everyone was confused at the beginning and everyone kept looking at each other to figure out what we were suppose to do. XD Anywhoots... Next scribe is Joseph.

Enjoy! =D

Newton's Corpuscular Theory of Light

April 7, 2008
Today in class we got our nature of light tests back and looked over it for mistakes on the smart board.
Afterwards we got new booklets which i nature of light part 2: the wave and particle models.
on page 2 of the booklet we read section 1.2:the nature of light: Early greece to 20th century.
then we were assigned to read section 1.3: Newtons corpuscular theory and rectilinear propagation.
