Ms. K was back and we continued the presentations. Thanks to Jordan's laptop for the presentation. There are still few people who didn't present yet so i guess some of our time on wed will be spend for presentations again. There's only two presentations for today so for the rest of our class time, we went over the solutions for Gravitational fields worksheet.

Monday's class, Ms. K was away and Mr Harrison was the sub for her. At first, we just went over the answers for the universal law of gravitation sheet and here's the answer:
- FG= 7.41 x 10^-12N
- a. m= 72.7kg
b. FG= 712.3N
c. Fw= 159.9 lb - a. double
b. 1/4 F
c. 4F
d. 16F - Gmoon= 1.62 m/s^2
the rest of our class time was spent to answer problems from the green book p.172 # 6, 7, 11, 13, 18 or the review chapter8 but don't do #s 4 & 7
i noticed that when no one was called to do the scribing, no one is really doing it. So I choose xxcoolguyxx to do the scribe for wed's class=)
