October 24. post, very late October 25 scribe as well

Okie dokes on the 24th of October we had a test on Projectile motion and that was hmm, not so good for me, but then it felt easy, however I did a lot of mistakes sad to say. That's all that happened on that day.

Okay, as for October the 25th,Ms. K handed back the tests, and geebus it makes me want to have a re-test, but I don't know if we're allowed to. After that we just did a study guide on Periodic motion, and we did the first part called Circular motion. We then were told to do some questions in the green book questions 9 to 11 and then we were supposed to do this worksheet that was on the table for homework, to practice some of the equations given to us. We were doing the worksheets on Centripetal Motion. That's it, that's all, have a good night everybody, sorry this was up late, I came from basketball conditioning and a bunch of other stuff, the next scribe will be Tim_MATH_y !! sorry dooodes, ahah.

Kasia's Scribe II

Hey there blogger buddies! So anywho I just got back from a concert so I'm sorry if this isn't the worlds best scribe post (don't expect much).
So today in class we handed in our finished calculations of our catapult project to Mrs. K. We then went over the questions that she had assigned from the duck book on the board, but as no one appeared to have done them or was paying much attention she assigned questions 29 a, b, and c as well as question 31 on page 115 to us for hand in at the end of class. 29 was fairly easy but 31 gave the whole class trouble so I'm guessing she will have some sort of explanation for us tomorrow. And BTW our TEST is TOMORROW, or today, depends on how you look at it. SO well I guess that is pretty much it. So goodnight and good luck!
And the next scribe is.................Oliver.

late scribe post

Hey sorry guys that I was so late to post my scribe I completely forgot. Well today we didn't do to much anyways just launched all of our catapults. Although many were like sling-shots that worked really well so good job everyone on the really neat looking catapults etc. Besides launching them we then worked on the questions to go with it to hand in and that was our class today. The next scribe is.... KASIA!!

Physics

Today in Physics class we went to the worksheet review chapter 7 and projectile motion II.we checked and answered the questions.and after that we did the question's 3 and 4 from chapter 7 and the 4 and 5 from projectile motion II, and also we discuss the Tossed ball. well i guess thats all folks.

Next Scribe: nee-cole

Thursday Scribe

Today in physics class we finished up the lab for The Analysis Of The Path Of A Projectile, to later hand it in. We were also given a ch.7 review and do ques #1 to 4. We also got a 2nd work sheet titled "Tossed Ball" with a diagram of a ball being tossed where we had to fill in the boxes, writing in the values of velocity components ascending, and your calculated resultant velocities descending.
REMINDER:- catapults due monday for the lanuch.
- Test on Wednesday oct.24th
Hall of fame-you're the scribe for Friday

Wednesday Scribe

We did a lab on Analysis of the path of a projectile. Test on October 24th. Next scribe = Victor. Awesome scribe by Van. Muhahahaha.

Projectile

Today in class we went over the Chapter 7 Study Guide Section 7.1: Projectile Motion, in which the answers can be found at the green book p. 123.

Ms. K gave us 3 worksheets:

1.) Time Elapsed graph

2.) The Trajectory of a Projectile Worksheet
3.) Projectile Motion I Problems ( 1-5 )

We finished Time Elapsed graph and The Trajectory of a Projectile Worksheet, through the answers given to us by Ms. K. The 1-5 problems (Projectile Motion I Problems Worksheet) can be solve using the formulas that Kristin posted on the blogs before me (^_^), and it will be corrected tomorrow.

Take note: Ms. K told us that the “catapult project” should be in 45 degree angle in order to make the range longer...

The next scribe will be Victor...

Today in Physics...

We went over the Momentum/Football worksheet, the Conservation of Momentum worksheet, and corrected questions 51 and 52 from pages 308 and 309 in the duck book(not the green text book).

We then started learning about projectile motion...

We studied an example involving a projectile falling off a cliff. The path that the projectile travels is called the trajectory. The horizontal distance the projectile travels is the range. The X(horizontal) component is moving at a constant velocity, while the Y(vertical) component changes it's velocity due to gravity. We use these equations:

Velocity of the X component : v=d/t
Velocity of the Y component: a=v/t or v₂=v₁=at or d=v₁t+1/2at² or d=(v₂-v₁/2)t or v₂²=v₁²+2ad

.....but, in this case the acceleration is due to gravity, so you can replace the "a" with a "g", and we all know that g=9.8 m/s²

Then we worked on a short lab involving the pushing of coins off a table with a ruler. Those labs were due today.

We also got a study guide that we will have time to work on tomorrow in class.

The Scribe for Tuesday's class is.......victor!
