<p>"you don’t need to memorize formulas…there’s a formulas sheet. with constants. 
"
WE ONLY GET FORMULA SHEET ON THE FR NOT THE MC!!! :D</p>
<p>pigs at sea…for some reason i think you’re right…!! crap, this is even worse…</p>
<p>yeah, sorry to bring down the mood more here…
but princeton review says you need to get 75% of questions right for a five…
don’t kill the messenger…i’m just the reason for the swine flu haha jk</p>
<p>princeton review says
5 75%
4 60%
3 45%
2 35%</p>
<p>(these are all greater than or equal to)</p>
<p>so if you got 50-55% right, that would be a middle 3</p>
<p>so for a 3, u need u get about 50% of the entire test? (MC + FR)?</p>
<p>You only need around 65+ for a 5</p>
<p>
</p>
<p>Sorry to break this to you, but the formula sheet is only for the FR section.</p>
<p>yes, aeroengineer is right…it’s only for the frq section…sadly…</p>
<p>Last year, I skipped about 5-10 questions on the MC and left 1 full FR blank along with partial credit on most of the others. I managed to get a 5. I think the Princeton Review may be trying to motivate you guys a little more… ;)</p>
<p>Make sure you all have a good footing in kinematics, especially projectiles and momentum. Basic circuit analysis is also a good idea. Also, there is usually a question dealing with thermo and/or atomic/nuclear.</p>
<p>redfirex67…you have just given me hope that i will not get a 1…i seriously wanted to ask my counselor if i could just not take it…but i have studied the princeton review…but now i feel like 1% more confident…</p>
<p>The key is to remember what you know. If you come across a MC question that looks like something you’ve never seen, skip it. Move on to questions you do know the answers to. There can be many easy ones near the end that most students never get to. For example, most of the questions I skipped were thermo related and the FR I believe was thermo also. So don’t fret if you are completely clueless on one topic. There are way too many topics in Physics B that it is nearly impossible to be an expert at every part.</p>
<p>(I’m hearing that soon the CB is going to split up Physics B because it covers too broad of a range of material. Maybe relating it to the Physics C layout.)</p>
<p>someone ask a physics questions and other people answer it lets have a 48 hour physics marathon!! everyone take out their redbulls lolz</p>
<ol>
<li>Which of the following quantities is not a vector?
a). Momentum
b). displacement
c). acceleration
d). work
e). impulse</li>
</ol>
<p>remember to explain</p>
<p>not a vector is something that does not have direction…is it b) displacement…
i’m kinda guessing by the wawy cuz i know it’s not d or e…</p>
<p>edit: i change my answer to d) work…cuz that’s the one w/o direction…right?</p>
<p>Displacement is a vector. (Distance is a scalar.)</p>
<p>work is not a vector</p>
<p>correct answer is D someone else ask a question</p>
<p>Newton’s second law gives the measure of
(1) acceleration (2) force (3) momentum (4) angular momentum</p>
<p>redfire he says which is not a vector. because most of them are vectors LOL.</p>
<p>Ya answer is d. work and all energy are scalars. you cant have direction for work yo.</p>
<p>jzhang, I was assisting anamai who initially said that displacement was not a vector. It is.</p>
