test on gravitational and electric field

wassap ya'll, emman's in da house.
today, we did test on gravitational and electric field unit, and that's it. that was easy.
and, i'm out, peace. Nd exams's in two weeks, ya'll better study hard, or else...

Gravitational & Electric Fields Review

Tuesday January 8 & Wednesday January 9

Hello fellow classmates,

Sorry for being late but here is Tuesday's blog.

On Tuesday all we did in class was correct questions on the smart board from the Gravitational Fields worksheet. We finished all the questions up to 9.

That was about it for Tuesday's class, since it was so short I will post Wednesday's as well.

On Wednesday we corrected the Chapter 5 Review on the board, so there is not upload for the answers. Questions 11 and 12 were for bonus marks if you handed them in. After that we received some new sheets, including a review for the Gravitational Fields unit. If you were not there remember to get the sheets. Remember the test is on Tuesday. We also started the Electric Fields unit.

That's all for Wednesday and Tuesday. Study hard!

Gravitational Fields Worksheet

Thursday, Dec.20

On Thursday the 20th it was an easy going class, we haven't done as much as we usually do.
Ms. K just corrected our homework and that was it for the day. so am here to hook you up with the answers in case u missed them.

Sheet # 1 Falling and Air Resistance
1- (most) a) a= 10m/s²
2- (a,b) b) a= 6m/s²
3- (d,e) c) a= 0m/s²
4- (still downward) d) -2m/s²
5- (c,f) e) a= -10 m/s²
6- (c,f) f) a= 0 m/s²

Sheet # 2 Gravitational fields of force relative to earth

1. Jupiter, 26.10 N/kg
2. Pluto, 0.31 N/kg
3. 3.72 m/s², 3.72 N/kg
4.Venus or Uranus
5. Neptune
6. Mercury
7. m=55 Kg 550N
8. 92N
9. F_g=3321N
10. 26.10 m/s²

sheet # 3 Falling and Air Resistance

1. Air Resistance = Weight
2. Air Resistance/weight is less
3. 0 N
4. Air Resistance= 100N[up]
5. F_net increases, acceleration increases
6. Gains more speed in 1st second of fall gains more distance in 9th second
7. F_net is different for both tennis ball and sand tennis ball, has greater F_net air resistance has more effect on lighter tennis ball, so its acceleration is less

On Friday's class we did a lab on friction, the equipment that we used for the lab are:

• 5 bricks
• a dynamics cart
• string
• brown wrapping paper
• wax paper
• sand paper
• plastic wrap
• 2 spring scales
• masking tape

Basically we measured the force of friction through many procedures in the lab.

Reminders!

1. Finish the questions on the last page
2. Create a graph for table 9-6 (Data and Observations)

Finally the next scribe will be.... Awot!

Nobody scribed this day so I guess I'll scribe it.

We were handed worksheets to work on during Ms. K's absence.

Wow. That was pretty easy.

Oh by the way, Ms. K informed me that we have a test Friday. Bummer.

Hello fellow bloggers this is AznFlame today and i'll scribe for today since nobody has scribed since my last post. Well today in class we did a lab to determine the gravitationalfeild strength within the class. We will probably hand in the lab tomorrow.

The next scribe will be Lee.
