***AP Physics 1 Thread 2014-2015***

Thanks! I’m not really in it for the credit, anyway :p… If I self-studied Physics C, will I be able to take the Physics 1 exam without additional studying, though? Is there a lot of overlap?</p>

<p>

No.</p>

<p>Physics C does not cover waves and sound, for instance, which are included in Physics 1.</p>

Awhhhhhhh D:! How much more self-studying is it? I’d like to take both tests @<a href="mailto:@">@</a>…</p>

<p>We’re only on Kinematics, and I’m already lost… :(</p>

<p>@glasshours just finished kinematics and just started dynamics, and god I barely understood kinematics. Took me a while to suck up my pride and ask the teacher for afterschool help, but it helped</p>

<p>@glasshours‌ @Zeppelin7‌
What made kinematics so hard O<em>o…? I watched a few videos online, and I found them to be easy. It might be because I have some calculus background .</em>____. … Give me a sample problem?</p>

The thing about kinematics is that there are multiple types:

  1. 1-D is pretty simple and straightforward
  2. 2-D is a little more complicated and needs comfort with vectors, but some are still very simple
  3. Some questions are tricky and give you non-SI units. Annoying but not hard.
  4. Then there are a couple that are rather difficult and ask for multiple things like maximum height, maximum distance, time for the object to reach ground, time for object to reach max height. This is where a lot of mistakes can be made especially if you are deriving equations under time pressure. One of the hardest I have seen is determining whether two objects collide.</p>

<p>That being said, I would say kinematics is much easier than dynamics just fort the fact that dynamics introduces the more complex notion of net forces and is more conceptual and not as intuitive.</p>

<p>P.S. If you are going to major in the sciences or engineering in college Physics 1 and 2 will not yield any useful credit usually. That’s not to say it wouldn’t be okay to take the exams this year and then take the C version next year, but you should definitely take C next year if you are doing one and two as a junior.</p>

<p>I’m currently a 9th grader taking AP Physics 1-2 in one year. I am also currently taking algebra 3-4 right now, and I’m just worried if I should be ok not knowing calculus even though the course is Algera-based. I can self-study a little calculus if its recommended and if so could anybody reccomend some topics in calculus that would help? Thanks</p>

<p>ps: AP Physics 1-2 is the only AP I’m taking this year </p>

<p>@dlang7 The course, as you said, is algebra-based. You need to know no calculus whatsoever.</p>

Ah, mmk. I did a few practice problems, and well, they are really tricky at times. For example, as you mentioned, maximum height would be when vertical velocity = 0 etc. No wonder they call it “problem solving,” lol. Is second dimensional kinematics stuff like angular velocity, by the way?</p>

<p>Yes angular velocity is a part of 2-D kinematics and so is relative motion, but these are only parts, the main part is projectile motion.</p>

<p>@jimmyboy23‌
Ahk, sounds good. For me, angular velocity is just not your dimensional analysis really well, relative motion is just a lot of trigonometry, and projectile motion is knowing how to use your equations. Sounds accurate O_o?</p>

<p>I think I’m doing pretty well now but does anyone have any online practice questions for kinematics?</p>

<p>@galaxyexplorer‌ You could try these: <a href=“http://wps.prenhall.com/esm_giancoli_physicsppa_6/16/4350/1113788.cw/index.html”>http://wps.prenhall.com/esm_giancoli_physicsppa_6/16/4350/1113788.cw/index.html&lt;/a&gt;
I’m not sure how difficult they are in terms of the AP exam as I still really have no clue as to how hard the actual AP Physics 1 exam will be.</p>

<p>Anyways, are most of you taking just the AP Physics 1 or both the AP Physics 1 and the Physics 2? Our school doesn’t offer these classes after they split from Physics B, but I am taking a dual-enrollment with a SUNY school that covers two semesters of college physics. Should I take just the Physics 1, or take both 1 and 2?</p>

<p>I felt that the Princeton Review was great in terms of the problems they give. The problems are much harder in the book than on the test which is good because if you can solve those, then you’ll be perfectly fine for the problems on the test. but honestly the book did a bad job in thoroughly explaining the concepts. I would consider buying Barrons or 5 steps to help you understand the concepts or you can try learning them by reading your schools textbook which is what I did.</p>

<p>I don’t think Barron’s has a book out for AP Physics 1&2 yet.</p>

<p>I’m a sophomore taking this class with no background on physics, and my teacher is AWFUL. First quarter just ended and we’ve only covered one-dimensional kinematics. I was just wondering at this point in the school year how far you guys have gotten? Can someone assess how screwed I am?</p>

<p>@Freak3yman84‌ I’m a junior in this class. We’ve just finished two-dimensional projectile motion. We’re onto force and Newton’s three laws now with free body diagrams, stuff like that. </p>

<p>@PoisonIvy2 So how far behind you am I? Did your class go from 1D Kinematics to 2D Kinematics and now you’re on Newton’s laws? Or were there any units in between?</p>

<p>Thanks!</p>

<p>Yeah right from 1D with vectors positive/negative direction, displcment time, velocity time, acc. time graphs. Then free fall, and upwards launch, then x-y axis projectile motion. now onto force and newton’s laws, like F=ma and inertia, stuff like that.</p>

<p>I would try to get the syllabus for your class (if there is one) and compare it to all topics being covered on this new exam, to make sure you’re going at an alright pace. Hey, for all I know my teacher has us going really fast to have enough review time in April. idk. Just make sure to check. </p>
