This is Lindsay scribing for Thursday's class.
We first watched a video on electric fields. Here are the answers from the handout:
1. charge, potential, field
2. determine height above sea levels
3. field lines
4. hard
5. no
6. down
7. elevation; downward slope
8. E=-v/R
9. direction
10. 1/R2
11. inverse
12. no
13. constant height above sea lel
14. yes; electric fieldis perpindicular to the surface
15. 10 000
16. ionizes the air, electrons accelerate
17. ability to do work when electrons flow; volts
18. Ep=qV
19. charge in chemical form
20. charge, energy electrical field, foce, volt/potential difference
We got another work sheet. Here are the answers:
1. loss PE = gain KE
2. force; distance; W=Fd; increases; equal
3. potential; voltage
4. 1V
5. 12J
6. 5000 V
7. 5000V
8. 5000V
9. .005J
10. charge
We did a lab and hand that in ASAP
We also got more handouts and a worksheet for long weeked homework!
next scribe is...caroline

Scribe Post
This is Lindsay, the scribe person for today.
In class, we watched a video that showed us examples of circular motion.
One example would be the Merry-go-Round. It has a fictitious Coriolis force. I think that's what the video told us, I'm not quite sure, sorry.
Another example was the roller coaster. The liquid in the container (the accelerometer)changed levels when it went around the loop.
The last example we saw was the carnival rotor ride. There was an outward inertial force. The people in the ride were in a state of equilibrium because of the artificial gravity. They were being pushed against the wall, away from the centre.
After the video we corrected the questions 13-17 on pages 152 and 153.
Ms. K showed us a free body diagram on the smartboard. The coin was traveling in a circular path and it experienced a gravitational force, normal force, and force of friction.
We're done with circular motion! (well not until the test...but you know what I mean)
Lastly, we received handouts about Work and Energy!
Do your homework and I hope you guys handed in your labs.
I choose you, bale-0ut! for the next scribe.
