What form was that?</p>
<p>I took form O E&M and I LOVED it!
The MC was mediocre to easy.
And the first and last FRQs were easy. The second one was okay.</p>
<p>I’m hoping for the 5, but probably gonna get a 4.</p>
<p>Had Bio, Mech, and E&M today…
Bio went better than I thought. Prob a 4.
80% MC 60%FR</p>
<p>I had form O for Mech. MC was a little harder than '98, most definitely longer too. I had to blindly guess on 5 of them… The FR wasnt bad guys… number 2 sucked though (block sliding down going circle wall thing). #3(linear and angular momentum problem) was the first time I did a problem like that. I hope I got it all right… The person has to be accounted for in the moment of inertia, correct??
75%MC 70% FR low 5</p>
<p>Electricity and Mag… Oh boy. You can probably guess which test I had. (Form G) MC was a bit hard… did expected on that though. Missed easy Qs because I forgot a formula or two…
FR … lollolololololol I knew I let myself down! I tried to get the easy and free points on 1&2. I did all of three though (: (the B-S law). I was the only one who took it at my school and hopefully I didnt embarrass my self by doing bad.
65%MC 55% FR LOOOOW 4</p>
<p>Did anybody else have trouble with Form O E&M FRQ #2? I honestly didn’t even know how to start. How’d you guys do on that question?</p>
<p>Can someone please explain what theta sub L was referring to in Mech #2</p>
<p>Also Form G EM #2 was ridiculous…freaking capacitors</p>
<p>@hiker13910 Are you talking about Form G or O in Mechanics?</p>
<p>Form G</p>
<p>Oh, I got Form O…Heard O was considerably harder than G in terms of FRQ</p>

<p>If anyone had Form G EM, #2 was almost exactly identical to 1996 #2.</p>

<p>Hey guys
So today was the AP exam…tough stuff.</p>
<p>I took the Mechanics exam, and with my class we were ill-prepared for it. Maybe it was the speed at which we took tests and learnt the material (because at our school, technically anyone who is in Calc or has taken Pre-calc can take this class, so the pace was slow) or maybe there’s just so much to learn. If you really want to be very prepared for the exam, I recommend learning the calculus of each topic along the way. There’s some calculus questions in there, and at least one in the free-response (which is usually like a distance, velocity, acceleration problem).</p>
<p>Here are the topics you should cover in your class:
Vectors (not too much on this)
Kinematics (you should memorize the equations)
Newton’s Second Law (F = ma)
which goes along with Free Body Diagrams (you MUST know how to do these)
Conservation of Energy/Energy (you should be comfortable with this)
Linear Momentum (basically, know that momentum is in x y coordinate form, so you can find overall momentum using Pythagorean - also know how force, momentum, impulse, work, and other stuff are related, because you will get questions that relate all of these)
Gravitation (know the force of gravitation, potential energy, velocity equations, and Kepler’s Third Law equation)
Circular Motion (know that a = v^2/r and how to apply FBDs to this)
Angular Momentum (sort of the same thing with Linear Momentum, except everything is converted to angular form)
Simple Harmonic Motion (know the equations for finding omega, and the equation for a simple pendulum)</p>
<p>I hope I didn’t miss anything there. That’s a lot.</p>
<p>So, if you cover everything there, and the calculus along with it, you should be fine. Do some practice problems with review books, and look at the FR on AP Central.</p>
<p>Also, here’s my little spiel on review books, especially for this year’s Physics: Mechanics:
5 steps to a 5 (McGraw Hill) - very good, although very broad. No huge mistakes found.
5 steps to a 5: 500 questions - many mistakes with a lot of the questions. Sometimes they change a decimal in the answer, which throws the entire value off, or they forget to mention a value needed (such as the mass of a car - 1000 kg apparently), but if you know what you’re doing, it’s fine.
Princeton Review - probably the best review book for any subject out there, but for physics it didn’t cover that much.
Barrons - very hard, like people have said before. Even harder than the actual exam (which says something). The material is covered very thoroughly though.
Rea - I liked this book, although it only had one practice test for mechanics (which was the downside)
Kaplan - very good, probably the best for physics, although I’m pretty sure it missed the topic of circular motion entirely (although I’m not too sure).</p>
<p>So you can look at this list, or you can just look at all of them, and take your pick.</p>
<p>@hiker13910 and @student03
For Mechanics, it doesnt matter what form you got. They’re the same questions</p>
<p>@Lanie49 You had form O and I had form G so our number 3 was different.
@hiker13910 Theta L was referring to the angle at which the block fell (I believe)- Didn’t have a clue how to do it.</p>
<p>The entire time I thought theta L meant the angle at which it LEFT the loop, like completed the loop and continued on lol. I skipped that part (and the corresponding one about the sphere) and feel like I got every other part mostly right so I think I’m good.</p>
<p>For MCQ, they might be the same, but I’m pretty sure FRQ was different. I heard Form G had a whole question about position, velocity, accelration, etc, while Form O didnt</p>
<p>Will the different forms have different curves? I tanked an entire FRQ and half of another on Mechanics O.</p>
<p>Since no one can access the other doc…discuss here:</p>
<p><a href=“https://docs.google.com/document/d/15xN7KBdVnlz241ufZBMOqieEMGMWo9CkJAstonQRO4U/edit”>https://docs.google.com/document/d/15xN7KBdVnlz241ufZBMOqieEMGMWo9CkJAstonQRO4U/edit</a></p>
<p>Fixed so anyone can edit.</p>
<p>What do you guys honestly think the curve for a 5 will be for the Mechanics Form O? I’m thinking a 50/90 or less because the 2004 one was that low and I found this one to be harder</p>
<p>I’m thinking 52-53/90. Everyone says that their test always seems way harder than it actually is. Also in 2004 they had a guessing penalty so it was a little lower back then.</p>
