<p>This thread can be used for both mechanics and E&M. I think we should get some questions going sooner rather than later, since these are very difficult exams. Who's here to study with me?</p>
<p>Pacman</p>
<p>I’m here with you, do you mind me asking where you are in your AP Physics C class?</p>
<p>We are currently on Ohm’s Laws and Joule’s Law. I think we are in a good spot. How about you?</p>
<p>I’m Mech only, but studying of any kind would be good…I’ve only done non-calc based E&M, though, but the any mech studying would be cool!</p>
<p>i’m here as well! i’m only doing mechanics; are you guys doing e&m as well?</p>
<p>Well my book doesn’t really have units and chapters and stuff, it likes to skip around so far we have done basic circuits i.e. ohm and kirchoff’s laws, Hookes law, Torque, and some other stuff I don’t remember, but when we start a topic we don’t necessarily go in depth on it and finish that topic right then in there like most textbooks with Units and chapters. We just did a section today on angular momentum.</p>
<p>I’m self studying mech only, but i would to study here too. I’ve just finish rotational dynamics.</p>
<p>Yes E&M is so hard :(. I’m only at Gauss’s Law but I feel that if I don’t keep up with this then I’ll forever fall behind…</p>
<p>Anyone want to get a Q&A session going so we can all work through various problems in lieu of may?</p>
<p>A ball rolls along a horizontal frictionless surface without slipping toward an incline. The ball moves up the incline a certain distance before reversing direction and moving back down the incline. In which of the following situations does the ball move the greatest distance up the incline before turning around?</p>
<p>A)the incline is frictionless
B)there is sufficient static friction between the ball and the incline to prevent the ball from slipping.
C)there is insufficient static friction to prevent slipping, but there is some kinetic friction.
D) the amount of friction is irrelevant
E)the situation described in this problem is impossible: a ball cannot roll along a horizontal frictionless surface without slipping.</p>
<p>Hey this is a good thread, we should keep it going.</p>
<p>I compiled all of the released exam questions and scoring guidelines currently on the CollegeBoard Website (From 1999-2009) and put them into a single .zip file for easy access. I figured this would be easier than having to sit through downloading each individual file to see the exam questions. It contains both the Mechanics and Electricity & Magnetism questions. </p>

<p>Well have you guys thought of an answer? Come on we need to keep this thread going!</p>
<p>I’m self-studying Mechanics.</p>
<p>Thanks for the doc! It’s going to help.</p>
<p>steel the answer to your question is b unless I’m mistaken, a ball cannot roll without static friction but kinetic friction hampers the motion…</p>
<p>We’re doing circuits and stuff now, I did mechanics first semester and we did Gauss’s law and stuff in February.</p>
<p>you’re correct drought, yes i know many are studying e+m, but i just thought to post some questions since ap exams are approaching.</p>
<p>bump 10char</p>
<p>i attended general physics course at a local college just to take the physics C test, but i cant find a school to take it at =( im scared that the deadline is soon and i wont be able to find anything <em>sigh</em></p>
<p>A 500 g object is moving a horizontal frictionless surface. Its displacement from the origin is given by the equation: x(t) = (3.50m)sin[(pi/2)t + 5pi/4].</p>
<p>a)what kind of motion is this?</p>
<p>b)what is the amplitude of this motion?</p>
<p>c)what is the period of this motion?</p>
<p>d)what is the frequency of this motion?</p>
<p>e)what is the linear velocity of this motion?</p>
<p>f)what is the linear acceleration of this motion?</p>
<p>g)what is the maximun kinetic energy of this system?</p>
<p>h)What is the maximum potential energy of this system? </p>
<p>i)What is the total mechanical energy of this system?</p>
<p>bumping up. How are you guys doing? I’ve finish mech and now I’m just prepping for the exam.</p>
<p>^ you’re not taking E&M?</p>
