Physics?

Test Preparation SAT Subject Test Preparation

<p>No calculators on the physics subject test. The problems are designed to avoid difficult math. For example, instead of being asked for the gravitational force between two 1 kg spheres that are .5 m apart, you'll be asked what happens to the force if one mass is tripled and the distance is doubled</p>

<p>Since books cost money and many don't have a decent list of formulas, I've compiled a list of formulas for this test:</p>

<p>(pdf format)</p>

<p>I haven't quite finished it, but hopefully it could be helpful to some of you...</p>

22

<p>Ive had a quick look at it, really nice and helpful =)</p>

23

<p>hey i got the sparknotes physics review. anyone ever use it? good practice tests/review? my book store didn't have barrons or PR so i was between the AP Physics B book and sparknotes lol</p>

24

<p>No calculator usage....
Does that mean we have to know all the sinus stuff by heart?
PR book just asked me for sin(30) :-/
Will I have to learn all the sinus numbers (lol!) or will they be given on the test / questions like this wont even occure?</p>

25

<p>sin (30) = .5 .. i would know only the sin / cos of the special angles (30,45,60,90 etc..) if u don't remember them just draw your reference triangle or whatever, x, xroot3, 2x</p>

26

<p>i think pr is a little harder cuz i did the practice test in the collegeboard book and got a 790 but I was in the 720-750 range in pr</p>

27

<p>be aware that the test in the college board book is always a lot easier than the realy one I only took honors physics and was just starting calc, I got a 800 on the collegeboard test, i was getting about 750 in Pr and got a 730 on the may sat 2 test</p>

28

<p>Uuugh...
I really hope you were just unlucky... >.<</p>

29

<p>most people don't take physics since it is one of the easier tests.. the percentiles are very low compared to say bio or us history so the latter tests look "better"... </p>

<p>the physics test should be an easy 800 without studying if you can get a 5 on the ap exam.. for bio and us history, a 5 on the ap exam doesn't necessarily mean an 800 so there's the difference..</p>

30

<p>^ You think taking US History and getting an 800 looks better than the same grade on physics? Wow.</p>

<p>US History is the most commonly taken AP class on the face of the Earth. Why? Because you could train a monkey to do decently well in that class and on the AP/SAT II, standardized multiple choice tests in history require nothing more than academic regurgitation. It's pathetic really. This is coming from someone who walked through to an 800 on the World History SAT II and a 5 on the AP World (APUSH results are pending).</p>

<p>The percentiles look better because armies of retards who also take APUSH sign-up for the SAT II. Colleges know this, and you fool nobody with a higher percentile. Half the kids taking the SAT II US History haven't even taken physics by the beginning of senior year. In physics, you're percentiles are against pretty bright kids who know what they're doing. </p>

<p>PS- I know many kids who have gotten 5's on the physics AP who didn't get 800's on the SAT II.</p>

31

<p>5 on AP? >.<
Our German educational system is really useless for SATs -<em>-
We do only one subject each semester :-/ So Im missing all of modern physics, thermo dynamics, optic (well, had the basics maybe 4 years ago? lol), electric (also only basics, some years ago).
Luckily, Ive got this nice Princeton Review book since yesterday.
Im now on page 299 and have written around 50 cards to remember formulars... -</em>-
Ugh, this really hot weekend has really been fully dedicated to the Subject Test physics.</p>

<p>No Idea when Im gonna study for math 2 (taking physics and math this june)</p>

<p>Ah and Ive done a practice test, I would score a 720-740 right now (kinda funny, cuz I still havent read about modern physics and the stuff about light, just skipped it). This kinda gave me hope =)</p>

32

<p>can someone direct me to a real SAT 2 physics exam adminstered by college board?</p>

33

<p>buy the collegeboard book for SAT subject tests or use PR or kaplan.. they are pretty accurate.</p>

34

<p>Just curious: </p>

<p>How do colleges view it if you take it twice and score significantly higher the second time?</p>

35

<p>they will completely disregard the first try so yea don't worry about it.. but they might think you are a freak if you got like 750 and then you retake it to get 800...</p>

36

<p>You guys may as well get some practice while you're "studying" here on CC...</p>

<p>A machine gun can fire 50-gram bullets at 1000 m/sec. The machine gunner can exert a force of 200 N on the gun while firing. How many bullets can be fired in 10 seconds?</p>

<p>a) 20
b) 40
c) 50
d) 100
e) 200</p>

37

<p>yea i'll go with b:
F=m<em>a=m</em>v/t
t= m<em>v/F
t=0,05</em>1000 / 200 = 1/4s
So 4 shots per second and 40shots in 10 seconds.</p>

<p>Didnt anyone else get totally confused with question number 66 in the first PR practice test? >.<</p>

38

<p>do we need to know the exact amu of protons, neutrons and electrons?O_O
or is the rough range enough? (knowing that its somewhere around 1.7*10^-27 for protons and neutrons)</p>

39

<p>dude this test is so general.. don't even worry about it</p>

40

<p>k thanks...
Why do PR and all the other books mention all these (useless) numbers :(</p>
