Review Day

So today we went over that review sheet Ms.K gave.

Answers:
1)0.25m
2)7.83m/s
3)a)6.4s
b)203.65m
4)a)0.8s
b)0.82m
c)5.68m


Later in the class, she handed out a Transparency Worksheet.

THE TRAJECTORY OF A PROJECTILE
Answers:
1)Trajectory
2)Projectile
3)Vx = Horizontal Velocity; Vy = Vertical Velocity
4) Stays Constant
5)Increases due to gravity
6)None
7)Gravity is acting on the droplet. The droplet is acting on the earth, meaning the Earth is acting on the droplet.
8)None; Law 1 - An object in motion stays in motion
9)Gravity does not affect the horizontal velocity, and it affects only the vertical velocity.
10) Yes because mercury has a greater mass.

Our test is tomorrow, so good luck everyone and study hard!

Oh yeah, and before I forget, the next scribe will be Christine.

Today in class we were asked to finish all three of our labs ( coin lab, projectile motion lab, and our catapult lab) and also do a work sheet with questions relating to the catapult experiment, this is due tomorrow.

Francis will scribe next.

Wednesday, October 15, 08

On this day all we did in class was work on the catapult experiment which was due, and it took the whole class to get everything done. People who finished early worked on the projectile motion experiment and such.

Thats all


Kamil will be scribing next...

Good evening ladies and gentlemen...
Today's class was kind fun and mostly enjoyable by everyone.
It was a good thing that everybody was busy working on assignment.
First we corrected the projectile motion 1, then miss K. hand out analysis of the path of projectile lab which we all worked on the rest of the class.
Thanks every one and have good night.


Next to scribe is Mr. YONAS.
