Tuesday Scribe

In Today's Class, we went over the Acceleration sheets on the boards. The answers for those sheets were:

Acceleration
1. a = 6.25 m/s²
2. a = 9.76 m/s²
3. Vf = 35.5 m/s
4. t = 4.4 s
5. Vo = 107 m/s

Accelerated Motion 1

1. a) Vf = 15 m/s
b) d = 19m
2. a) Vf = 200m/s
b) d = 913m
3. a) a = 1.5 m/s
b) d = 116 m
4. d = 250 m
5. 5.6 m/s²

After correcting our answers, we read pages 19 - 22 in the Physics: Concepts and something... textbook and worked on questions 35 & 28 on page 33 -34.

The next scribe is Melissa.

11/25/07

Today, in class, we went over the sheet that was handed out on Thursday. The sheet dealt with distance-time, average velocity, and average acceleration graphs. We are now to work on the sheet labeled 4.1 guide and another sheet. To remind everyone, the 6 page sheet(Appendix 3.8) handed out on Wednesday is due. Also, the test on Kinematics is on Friday.


The next scribe will be Anh-Thi.

Motion Graphs

MOTION GRAPHS
November 22, 2007 (Thursday)

We played with Ms. Kozoriz's graphs on her SmartBoard with her sensor. We learned how position-time graphs and velocity-time graphs worked, and how to read and obtain data from them. We forced our classmates to move away and closer to the sensor while the sensor records the data on graphs on the SmartBoard. Fun class.

Vectors

Well thank you so much Eddie for choosing me for scribe, since you tried to be mean and it backfired because we had a substitute,haha. But enough of fun and games our substitute was Mr.Kidd, who went over Study guide 4 (section 4.2:Components of Vectors), so I will supply you with the answers for anyone who didn't get them,
1) b. 90°
2) b. origin
3) c. quadrant 3
4) b. B
5) d. sinΘ=B(у)/B
6) c. cosΘ=D(x)/D
7) c. C
8) b. FsinΘ
9) c. FcosΘ
10) c. E
11) c. R(x)= (-1.4 km) + 4.0 km + 1.5 km = 4.1 km
12) c. R(y)= (-3.8 km) + 6.9 km + (-1.3 km) = 1.8 km
13) a. R<>
14) c. Y=-R
Mr. Kidd was also nice enough to help us with our vectors assignment and went over all the questions and showed us how to do them! But I'm pretty sure that we'll go over them again with Ms. K when she returns. So I'll leave that for the next scribe which will be nounith1.

Vectors

Today in physics we received our Nature Of Light 2 test back so we can correct it. We also got a hand out sheet called 4 Study guide Properties of Vector. We corrected it about 20 minutes after anyways so you should have it but here it is for those who don't.

1. 6km E
2. 6km N
3. 6km NW
4. 4km S
5. 3km W
6. 5m SE
7. 40m SW
8. 6km E
9. 4m SE
10. 500m W

11. B 12. D

13. B F H
14. B F G I
15. B F

16. TRUE
17. FALSE
18. FALSE
19. TRUE
20. FALSE

Appendix 3.6 is due for those who didn't already hand it in.
Lauressa can scribe for tomorrow!

Today,in physic class, Ms K. let us read 4 pages of the whole booklet about Kinematics, she corrected the Kinematics-Frame of reference,and handed out the study guide to us . That's all we studied today.
Mary Ann will scribe tomorrow.
