*******Official AP Physics B/C Discussion/Prep Thread*******

<p>My instructor told me that there was a special focus on electrostatics.</p>

<p>fignewton,</p>

<p>this is because of the wave nature duality of the electron. Apparently, when things are really small, they exhibit a characteristic similar to light. Thus, a charged particle like an electron is able to move through without losing energy. And there is something about heisenberg’s principle in there too.At least thats what my chemistry teacher said when she was teaching us the quantum chemistry</p>

<p>Also, according to the de Broglie guy, everything that has matter also exhibits wave-like properties. The reason it’s not apparent is because of his formula</p>

<p>lambda = h/p (where lambda = wavelength, h = planck’s constant, and p = momentum)</p>

<p>Planck’s constant is very small (*10^-31 I think), and since p = mv (mass * velocity), our wavelength is negligibly small. Light particles [no pun intended :)], on the other hand, are small enough that they exhibit both wave-like and particle-like properties.</p>

<p>sn3, how does your teacher know
is he part of the ap committee or something</p>

<p>6.626x10^-34…God, why do I know that?</p>

<p>What is that? ^</p>

<p>Planck’s constant</p>

<p>This might be a dumb question.</p>

<p>But do we get a formula sheet for section I of the AP Physics B (Multiple Choice).</p>

<p>I know we get no calculator for Section 1,
but we get calculator and formulas for Free Response.</p>

<p>My teacher is an effing nublet; she says we get equations on both parts, so I’m confused.</p>

<p>no formula sheet in mc.
is centre
of mass included for the B exam</p>

<p>^ No.</p>

<p>out of nuclear physics, and optics, what are the chances of a frq in these?</p>

<p>Question- i havenot done many labs this year- actually the only one i did was pendulum. i am trying to get a 4. how do i proceed now that i have 36 hours left. is there any place online i can review the important labs? if i skip all lab based questions, how much loss do i suffer (approx. how much is lab based)?</p>

<p>10-15 points. There’s usually an FRQ devoted solely to making a lab.</p>

<p>I suggest that you just read it and write as much as you can think of that makes sense. They give points for almost anything that sounds reasonable. Don’t just leave that (or any) section blank.</p>

<p>does the AP physics B test cover the types of problems where, for example, somebody is spinning in a chair with their arms extended and then they pull them in and spin faster?</p>

<p>u only get a table of information for section one</p>

<p>Is Nuclear Physics/ Electromagnetic Induction big in Physics B?</p>

<p>does the AP physics B test cover the types of problems where, for example, somebody is spinning in a chair with their arms extended and then they pull them in and spin faster</p>

<p>Good question.</p>

<p>Nuclear phys is like 5% of the exam and electricity/magnetism is pretty big in the exam.</p>

<p>thanks unleashed.</p>

<p>bco- that is conservation of angular momentum and that’s the C test as far as i know.</p>

<p>Angular momentum is on B. L=mvr</p>

<p>cool, thanks. i thought i remembered it being easy. I didn’t miss a single question all year in my physics class, but that was mostly doing rote memory before every test (damn you APUSH taking up my actual study time!), and now im kinda screwed for this AP on monday</p>

<p>llpitch, according to Princeton Review, torque is included. Angular Momentum is NOT included for Physics B. This is, once again, accordingto PR and I am following it. if it is in fact included, can u please tell me what other rotational concepts are there? I have only done torque now.</p>
