Friday March 7th Post
Hey guys it's Albert. On Friday I believe we did a lab on the conservation of momentum, one object colliding with another. We rolled a sphere down a little ramp colliding with another sphere at the end of the ramp, set up at an angle either to the left or to the right. I'm pretty sure we'll be going over the Impulse and Momentum and Chapter 9 Study Guide sheets so have those ready for Monday. Other than that, there's no homework. Hope you guys had a good weekend, I sure did! Next scribe is Kevin
1 - Thursday, March 6, Scribe
Today's class there was a brief over view of momentum. The overhead will be uploaded later.http://phyr1203dmci.blogspot.com/2008/03/elastic-inelastic-collisions.html
This was what Ms. K. went over on the smart board.
There was a few worksheets which needs to be worked on:
Chapter 9: Study Guide
Chapter 7: Momentum
9: Study Guide
Impulse and Momentum
The next scribe is...
BERTMAN!

Scribe Post For Monday March 3, 2008
Hey everyone it's Robert here and I'm picking up some slack for Monday's scribe post.
On Monday we came into class with a nice start to the week. We got to watch a movie on momentum. We were instructed by Mrs. K to take down 5 points that we learned during the movie. These are the ones that i took down just in case someone missed out:
- the higher the mass of an object moving at the same speed, the more momentum
- momentum=m*v
- a = F/m a=chg in v/t
F t = chg in (m*v)
F t = delta m*v
impulse = delta momentum
- doubling the time of the force, doubles the momentum
- you can change the momentum of an object with an impulse (big force, small time) or (smaller force, longer time)
- short time to stop object means larger force
- Big time to stop object means smaller force
Well that is it for this scribe and I'll see you guys back in class tomorrow. The scribe for today with choose tomorrow's scribe.

My very late.....blog post
This post it is going to be for Tuesday March 4th. On Tuesday we went over the first part of the chapter 9 study guide. Ms. K said that we will be going over the Conservation of Momentum another day so have it done anyway. We were also assigned questions 50 -51 on pages 308-309 in the duck book, answers to the questions are located in the back if you would like to check.
My next post won't be late lol

Scribe
Hi guys sorry I'm late .
On Thursday we were doing the lab about friction.
On Friday we did the test about Dynamics. And don't forget to read Chapter 9 in the Green Book.
That's all.
Next scribe is NaTaSha
