Newton's Laws of Motion!

Whoops sorry guys I didn't know I was scribe last week... My apologies!
*ahem . . .

Today we dug right into the textbook first thing to finish Chapter 5 Study Guide. I'm not going to write down all the answers because I'm sure you can get them from your fellow peers, and if I did write them down it'd look ..quite abstract ...

Anyway, one thing you must remember however; If there is no net force on an object, then the object remains at rest, or moves with constant velocity in a straight line.

After we went over the answers to the front side of that study sheet, we received three worksheets based individually on Newton's Laws of Motion; Inertia, Force and Acceleration, and Action and Reaction. We went over the first two worksheets (3-1, and 4-1), and 5-1 was assigned for homework.

Tomorrow we will be doing a lab based on Newton's 2nd Law. We were also told that we would expect a test on Tuesday (Dec. 11th).

Ending my blog post I will choose the next scribe whiiich iiiiss .... (I'm really tempted to choose Justus just to see how mad he'll get this time.. hahaha) but I'll chooooose Jessica!

JANET OUTT! :)

Scribe post for Friday, Oct. 19th

Hey guys! Sorry it took me a while to scribe, but it's the weekend so no worries.
Well, we started our new unit in class on friday, Significant Figures. We got a few worksheets on the rules, information and practice questions.

Some tricky ones (I found were tricky at least..) was..
1) 3.007 km
that zero is significant because it is between two significant figures (3 and 7)
* rule: zeros between two other significant digits are always significant
2) 819 000.0 g
this measurement has seven significant figures
* rule: all final zeros after the decimal point are significant
3) 60 000 x 10³ g
this measurement has only 1 sig fig.
* rule: zeros used only for spacing the decimal point are not significant

We also did some practice on sig. figs with mathematical calculations. Takes some extra thinking but we'll get used to it ... Oh and we also did some unit conversions.
That should pretty much cover the class... Test tomorrow! (Monday) Study hardy! Good luck everyone :)

Oh yeah scribe ... (WOW they'll have an easy scribe, just say we had a test?) Is ... um.. hanz?

"Chapter 14?! Wow you guys are fast!"

Title quoted from Mr. Substitute teacher that we had today. I must say he's one of the best substitutes I've had in a long time. Very interesting indeed.

Anyway... HELLO! I'm Jadanet, I couldn't scribe yesterday because I had work afterschool, and wouldn't be able to access a computer until after 10. So here I am today! It's late right now too.. but that's okay because it's the weekend :D

So today what we did in class was a CHAPTER 14 Study Guide booklet. Okay... really it was 3 pages, not a booklet persay.. :) It consisted of a brief summary about all the waves and things related to it that we've been covering for the past week. In the format of "fill in the blanks", we used textbooks to aid us. That took a majority of the class period and at the end of it we went over the answers.

Here are the answers if you couldn't catch them:
1) TYPES OF WAVES
- mechanical, material, electromagnetic, no, particles, matter, 3, perpendicular, motion, parallel, motion, surface, parallel, perpendicular, single, continuous, vibrating, harmonic.

2) THE MEASURES OF A WAVE: FREQUENCY, WAVELENGTH AND VELOCITY
- shortest, motion, cycles, second, hertz, hz, hz, f= 1/T, T, f, wavelength, lamda(λ), high, low, v=λ·f

3) AMPLITUDE OF A WAVE
- maximum, equilibrium, energy.

4) WAVES AT BOUNDARIES BETWEEN MEDIA
- amplitude, frequency, property, equal, equal, incident, transmitted, energy, reflected, most, little, inverted, erect, frequency, amplitude, speed.

5) SUPERPOSITION OF WAVES
- independently, displacement, sum, displacement, superposition, same, greater, shape, size, opposite, zero, destructive interference.

6) STANDING WAVES
- undisturbed, destructive, displacement, constructive, standing, stationary, standing still.

And that's all we did and covered! I'm guessing we'll be going over reflection, refraction, diffraction and interference of waves on Monday. So study hardy for the test on Tuesday!

Scribe on Monday will be "Hi I'm Justus"! :)
