MERRY CHRISTMAS!!!!!! ((:
and
advanced
HAPPY 2009!!!!!!
haah i know it's totally un-physics related but still yenno. yea. xD

Physics in the real world, sort of.
Here's something I found interesting, very physics related.
Watch the video.

YOSH!...this is Cloud Strife filling in for today...since no one has been scribing for the last couple days...Anyways, I'm only going to inform the class about what happened today...Here we go!...
At the first part of class, we read page six of our booklet "Grade 11 Physics: Gravitational Forces."...what it basically said is that if two objects with different masses are dropped at the same time, they will also land at the same time. This is because their acceleration is caused by the same gravitational force, if I'm not mistaken. Oh, and feathers fall more slowly because of air resistance...if you still don't understand, I suggest that you read the page on Acceleration Due to Gravity for yourself.
To test this theory out for ourselves, we also did an experiment for the rest of class. In this experiment, we had a rubber stopper attached to a string. The string gets shorter and shorter throughout the experiment and we need to find out whether the change in string length affects the gravitational force or acceleration on the object. This lab is due tomorrow, so you should answer the 6 questions on the back ASAP.
That was basically all we did today in Physics class...so I guess I'll be on my way. Hmm...the next scribe...will be...Johnl I CHOOSE YOU!...
Cloud Strife...out
SUBLIMINAL MESSAGES!!!...I wonder if anyone even noticed that this was here...for those of you who have found this, you must be really observant, somewhat of a genius...or just really, really, bored with nothing else to do...then again...you might've just came across it by coincidence...either way, good job...

The Cart Went BOOM~
Title inspired by that 'incident' that happened today. Don't worry PJ, we know it was Matthew's fault. Haha just kidding...
So, I forgot that I had to scribe yesterday, and I almost forgot about scribing today too! Sorry about that! I'll try to remember everything we did.

Believe it or not, I'm having trouble remembering. OH! Right, we did a lab!
So the purpose of this lab was to get a better understanding of Newton's Second Law.
Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object depends upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of he object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
Now, I'm having trouble explaining the lab. It basically involved a cart, 3 different weights (100g, 50g, and 200g), string, washers, and this timing device (forgot what its called). Put that together and you have our lab!
After that we had to record our information and create a graph. We had class time today to complete it, but if you didn't finish Ms. Kozoriz said it can be handed in tomorrow.
I'm sorry this post was late and I apologize that it wasn't in full detail! It's just... hard for me to explain. D:

-CRAP I FEEL ASLEEP
Anyways...
Summary of the day:
So last Monday, we watched a video about Newton's First Law of Motion. We had to list 8 important points from the video.
More on Newton's First Law of Motions here: http://en.wikipedia.org/wiki/Newton%27s_laws_of_motion (IT'S ALSO IN ONE OF THE WORKSHEETS THAT MS. KOZORIZ HANDED IN)
Vocabulary:
- inertia: the property of a body that any change to its uniform straight ; equivalent to its mass.
- net force: the combination of all the forces that act on an object.
Handouts:
Chapter 5 Study Guide
Grade 11 Dynamics: Newton's Law of Motion and The Four Fundamental Forces
Kinematics Word Search
TOTAL OF 4 HAND OUTS
Well... That's it...
Next scribe is arielle!
