May 31

Today we were given our exam reviews and also started our new unit on electricity.

We preceded the unit with a lab; using a light bulb, wire and a 'big' battery, we were to find a few ways on how to light the bulb, and a few ways where we couldn't. We were to illustrate the circuit diagrams in our hand-out booklet on the back page of the lab.

Within the booklet, we were to read pages 5 to 12 and were to do worksheets 44,45 & 46.

The current, I, is measured in C/s and is represented by the unit A, amperes.

Potential Difference, V, is measured in J/C.

Power, P, is measured in J/s and is represent by the Watt, W.

I=q/t V=E/q P=IV E/t=IV

P=(q/t)(E/q)=E/t

P=(1 C/s)(1 J/C)=1 J/s

Please feel free to correct.

THURSDAY & FRIDAY

On Thursday we went over the Acceleration I & II worksheets, we were individually assigned a question from each to illustrate our answers on the board.

Well I'm not going to write down the answers because it will waste too much of my time; if you weren't there or chose to be negligent to not copy down the answers, then please get them from a classmate or try them on your own. They are not difficult. :P

On Friday, were assigned pages 95-103 to read on RELATIVE MOTION in the IRWIN PHYSICS TEXTBOOK. On page 103, concept questions were assigned 1-2.c. beneath the figure 3.38.

Of course many students signed out textbooks for the weekend. Did you borrow one? Please try return it before the test tomorrow! Oh, and good luck! Refer to Chemutai's post to assist you in deriving formula's from different types of Displacement-Time graphs!

The next person to scribe is JANNA KAMINSKY hehe
