Homework Statement I was doing d and had a question because I believe my response is perfectly acceptable but yet it does not reflect the scoring guidelines at all. By the way I believe this is free response #2 on the 2006 Form B AP Physics B test...

Homework Statement Hi, I am confused with what exactly I need to know and what I do not need to know for this class. Our textbook were using at my school is, Physics for Scientists & Engineers with Modern Physics Third Edition Douglas C. Giancoli this book covers a lot of...

ok there is a picture that goes along with it, i will try and draw it in as best i can. We've got a 12 volt battery. a 4 ohm resistor is in series with this big thing I am going to describe next. A two ohm and 1 ohm resistor that are in series are in parallel with a 5 ohm and 1 ohm resistor...

Building a car in AP Physics, Need Suggestions! Homework Statement Hello, I am in need of suggestions on a project that was recently assigned to my AP Physics class. The challenge was to make a "Tank" (any vehicle) that will go down a ramp, shoot a projectile over a 1.5ft wall, and go back up...

Has anyone here taken the College Board AP Physics exam? I'm currently taking AP Physics online and hate it (more because it's online than the difficulty of the content, though, I think). I'd like the college credit, but it can hurt if I do poorly, too, and I'm not sure how well I'll be...

Hi i have the 2004 ap physics c multiple choice exam but I do not have the answers for the mechanics section. I would be willing to trade a lot of exams just for the answers to the mechanics section. thank you

As you all have seen, I am completely lost, but within the last two hours of being a member, I now know how to add and subtract vectors. Anyway! I made the image, because there is a diagram, and I have some clue as in what to do. My head is still spinning from the 40 vector addition/subtraction...

I'm currently a senior in HS, and I've gotten a 5 on the Physics B AP exam and hope to get a 5 on the Physics C AP exam (mech and electro). I asked my teacher what I should do (I'm going to University of Texas at Austin; ME major) about the credits. Some posters here at this forum have...

Homework Statement First, this is not an assignment, per se, it is for my own help, and If someone could help me work it through that would be much appreciated. An object of mass 1 Kg is launched at an angle of 42° from the horizontal at 180 m/s. A force of drag acts on it that is dependant...

Where can I find some old (2000 - 2008 ) AP Physics C Mechanics exams, preferably with solutions? I'm looking for both multiple choice and free response. Any help would be much appreciated, Robert

Alright so I just wrote an AP physics test and one of the true or false questions was: A horse pulls a cart and the cart pulls back on the horse with the same force. Does the cart move? (the cart starts at rest) I said false because in order for an object to move it needs a net force but...

In a heat engine is the net work negative or positive? Also, What about a refrigerator?

Homework Statement A block of mass m hangs on the end of a cord and is connected to a block of mass M by a pulley arrangement. (m hangs freely, M is attached to the string, and is on a table top. (So m is attached to a string which goes therough a pulley changing the strings direction 90...

we are only doing mechanics the whole year, and my teacher sucks. He doesn't teach us, I have the book University Physics 9th Edition. The book is literally horrible. we started class a week ago and I'm trying so hard with no results. We are on vectors which I find very complicated. How can I...

Hi everybody, I had 2 HW questions that I didn't get for my physics class, and I would really appreciated if you could explain them to me. They're pretty simple, I think, but the way they're worded makes it difficult to picture. 1) Two trains, each having a speed of 30 km/hr, are headed...

Currently I am enrolled in a regular physics class because their was only one AP Physics B class period and it affected my Latin II course. So I took Physics at a votech where I am also taking an engineering class. My question to all you physics pros is do you think I could self study and...

I just discovered that this year I am going to be teaching AP Physics C (the one with calculus) - just the mechanics curriculum. And the school does NOT have any textbooks for the students yet. So I was just asked to make a textbook recommendation. In the past I have taught AP Physics B...

Hi! I believe that I have asked a question to this similar before but I was unable to find it. I am going into my senior year of high school and I have the choice to take AP Physics B or C. I am currently signed up to take AP C, but I have been wondering lately if that's the best choice since...

Hello all, I'm a high school student in transition from junior year to senior year. And I was wondering if anyone thinks that it would be a good idead to take AP Physics as opposed to AP Psychology? When I go to college I plan to major in a science, but I'm not sure which course will make...

I hope I posted this in the right place... Anyways, I have just about finished my junior year of high school, and I have been looking forward to taking another physics course in my senior year. Because the sequence of science textbooks continues with this...

Sorry I didn't know where else to post this. But I thought that test was way harder than any of the practice tests I've taken. The free response, at least.

Hey does anyone understand how to do the 1995 Free Response AP Physics Mechanics question?? Specifically, the question about Potential Energy? I understand that F=-dU/dr but that is about it!

Hai guys iam kinda new here, this is actually my first post. So after i chose to independently self-study the whole of AP Physics C, i ended up compiling a list of books i needed. They are: Main: -Halliday, David, Robert Resnick, and Jearl Walke. 2008. Fundamentals of Physics, 8th ed...

Hey everyone hows it going? I am not sure if this is the right place to be posting this question, but hopefully it is. My names Shawn and I am a senior in high school. I currently have AP calculus and gen physics, and I plan on taking the AP calculus test (ab) and hopefully the physics AP test...

What's a good study guide for scoring a high mark on the exam? Is "Cracking the AP Physics B Exam, 2009 Edition (College Test Prep)" by Princeton Review good? It seems popular.

I am not exactly sure if this topic if relevant to this thread, so sorry in advance if it is not. I am currently in the 9th Grade, my AP Physics class is doing a individual project and I have absolutely no ideas. I am thinking about a Gauss Cannon or something. Maybe a levitating device such as...

A 2-kilogram block initially hangs at rest at the end of two 1-meter strings of negligible mass as shown on the diagram above (I'll explain this later). A 0.003-kilogram bullet, moving horizontally with a speed of 1000 meters per second, strikes the block and becomese embedded in it. After the...

AP Physics and college major... Hi, I need to know something about college... Assume I score 5s on both the AP Physics B and C test, and in college I want to major in Physics and go on to grad school for some area in Physics. I plan to take Honors Physics BTW. Is it recommended that I use...

Is it even possible? I have a Princeton AP Physics book that is supposed to prepare you for the test, but is that enough? It's almost impossible for me to take this class, but I feel I could do well on the test. Would Barron's or Princeton cover everything I need to know for the test?

Hello, I've lurked anonymously for quite a bit on these forums, and until now had no reason to register and ask a question. Background: high school senior with (otherwise) high GPA(3.9) and fairly good ACT score (31) seeking advice and consulting from experienced PF member. Now that...

Okay so I'm taking AP Physics B at my high school this year (i'm a senior) and I really enjoy it and I do well on all of the tests so far (I do usually get 1 or 2 problems wrong tho...my average is between 80 and 90 percent on tests). I really like Physics and all of the theories and stuff but...

Okay so I really, really liked Physics pre-ap last year. We had a great teacher, and I understood everything. Fast forward a year later, and that teacher left, and the new AP teacher is okay. He's a great guy, but I can't really grasp the way he teaches. Last year I was in AP Chem, and hated...

I got a take home test for AP Physics B and I've completed it. I just wanted to check with some people to see if they agree with some of the questions I had some difficulty with. I'll list the questions & how I thought they are solved. Any and all feedback is greatly appreciated- thanks for...
