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!

anyone have the solutions to the 1995 free response for physics C ap test? I have most of it done, but i just want to check it with the answers.

I was looking for information in regard to Acids and Bases. I'm having a awful time with conceptual questions concerning this chapter in class, and I'm getting pretty frustrated. Any practice questions / supplemental in depth tutorials would be nice. Thanks!

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...

In the laboratory, you are given a cylindrical beaker containing a fluid and you are asked to determine the density ρ of the fluid. You are to use a spring of negligible mass and unknown spring constant k attached to a stand. An irregularly shaped object of known mass m and density D(D>>ρ)...

To demonstrate standing waves, one end of a string is attached to a tuning fork with a frequency of 120 Hz. The other end of the string passes over a pulley and is connected to a suspended mass M. The value of M is such that the standing wave pattern has four "loops". The length of the string...

A spring that can be assumed ideal hangs (vertically) from a stand. a. You wish to determine the spring constant k of the spring. i. What additional equipment do you need? ii. What measurements would you make? iii. How would k be determined from these measurements? b...

Homework Statement A 2kg block and an 8kg block are both attached to an ideal spring for which k=200 N/m and both are initially at rest on a horizontal frictionless surface. In an initial experiment a 0.1kg ball of clay is thrown at the 2kg block. The clay is moving horizontally with speed v...

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...

[SOLVED]AP Question involving Ideal Gas Law - Thermal Physics - Pressure I am having some trouble with an old ap problem(PART C ONLY), see below: Homework Statement 1996 AP PHYSICS B Free Response Question: The inside of the cylindrical can has a cross sectional area of 0.005 m^3 and...

Does anyone have a link or multiple choice questions for old AP physics B or C?

Looking at an old AP multiple choice test, I found this question and answer: A satellite of mass M moves in a circular orbit of radius R at a constant speed v. Which of the following must be true? One of their "true" answers states: The net force on the satellite is equal to MR and is...

Homework Statement 1. A 2 kg block and 8kg block are both attached to an ideal spring (k= 200N/m) and both are initially at rest on a horizontal frictionless surface. In an initial experiment, a 0.1kg ball of clay is thrown at the 2 kg block. The clay is moving horizontally with speed v when...

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...

Two 10 kilogram boxes are connected by a massless string that passes over a massless frictionless pulley as shown above. The boxes remain at rest, with the one on the right hanging vertically and the one on the left 2.0 meters from the bottom of an inclined plane that makes an angle of 60° with...

I got a vial of fruit flies from my AP Biology teacher for Christmas, lol. Gotta observe them for two weeks and then we're going to study genetics by breeding them.

Yeah I know I've asked about the Physics AP tests, but how about Calclulus BC (obviously, if I got a 5)? I don't plan on doing theoretical physics in the future, just FYI.

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...

Homework Statement A 20 kg mass released from rest slides down a frictionless plane inclined at an angle of 30 deg with the horizontal and strikes a spring of spring constant K=200 Newtons/meter. Assume that the spring is ideal, that the mass of the spring is negligible, and that mechanical...

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...

5. A plane flies from base camp to Lake A, a distance of 280 km at a direction of 20.0 degrees north of east. After dropping off supplies, the plane flies to lake B, which is 190 km and 30.0 degrees west of north from Lake A. I'm not even going to write the actual question part, since...

Hi All, from this page: http://en.wikipedia.org/wiki/Saltatory_conduction If at node N1, an AP is generated and then the passive spread initiates another AP at node N2, is there 2 APs existing at the same time? In fact, the second AP is ever initiated before the first has ended. It seems...

I'm taking the AP class on calculus AB, and I want to order a book. Anyone would recommend one? I think the Princeton Review is the best one, but the Kaplan's and Barron's seems good too, so any opinion would help. Also I'm taking AP macroeconomics. I know this is not a a topic that people...

Hey guys, I am taking AP physics C in high school. So far i have found it very easy, because physics last year came very easy to me. I want to self study for the electro/magnitism portion, because in our time we can only prepare for the mechanics portion. I have the textbook Fundamentals of...

I. A model rocket is launched straight upwards with an initial speed of 50.0 m/s. It accelerates with a constant upward acceleration of 2.00 m/s2 until it's engines stop at an altitude of 150 m. I found a thread with an extremely similar question, but the only reply that showed up was a...

Don't know how AP got the scoop, but they're reporting that Obama's VP choice is Joe Biden. http://www.msnbc.msn.com/id/26010055/ A good choice. He's definitely good in the "attack dog" roll.

Homework Statement Assuming you have a bow that behaves like a spring with a spring constant of 168 N/m and you pull it to a draw of 54 cm, to the nearest joule how much work do you perform? Homework Equations The force of a constant spring is f=-k(x) where x is the displacement and k...

I'm beginning my undergrad education this fall. I took AP Calculus in my junior year of high school. My school didn't offer any math after AP Calc and so I haven't done any calc for over a year. Does anyone know any good websites where I can go to review calculus concepts before I start college?

I know that smooth and cardiac muscle cells (myofibers) are connected to each other by gap junctions. How are skeletal muscle cells connected to each other (to transmit the AP)? Thanks, any responses appreciated

I'm going to be a senior in hs this fall and am still fretting over my schedule. It's either IB Chem or AP Comp Sci A. I can't take ap chem because i don't have space for the dbl pd class but ib covers most of it and with a little self-study (i have had friends who successfully done this...

While many in GD know me fairly well, I thought I'd make an introduction here, as next year I'll be taking AP Biology as a high school sophomore and know I'll be here A LOT.

Ap Physics Questions! Please Help Me! Highlyyy Appreciateddd! I haven't done any physics work in about half a year n now i need to do sooo many questions in about a months time! ='( pleasee help me with these questions! I would HIGHLY HIGLYY appreciate it sooooooo much for anybody who would...

Hey Everyone! I'm going to be a Junior in high school next year and I am wondering what math course to take. My school has a schedule where there is only 4 classes a day; but they all run longer. So you can get through a normal math class in half a year with just as much time in the class room...

Passing the AP Physics C Tests usually gives credit at college for a similar class. However, I was wondering, if I'm majoring in Physics and did pass the AP Physics C Tests, should I skip the classes in college and move on? Or would it be better to take the classes at a college anyway in order...

i need links to previous AP physics B test, mainly 1988 because my test is going to be stuff over that. anyone that can help, it would be greatly appreciated.

For a school project, I am going to visit a local summer program for abused children and am going to bring supplies for and guide them through several simple (elementary to middle school level) experiments and presentations. The one problem is, it is supposed to inspire these kids. I made a list...

My biology teacher has assigned us a post-AP project that must involve service to the community and science in some way. My group has decided to do a "science camp" over the summer with disadvantaged elementary and middle school children. We will attend summer programs for these kids and give...

What did people think? It may have been the hardest thing I've ever seen, and I am a very prolific calc and phys student. The E&M free response was very very ridiculous, especially #2 where you had to plug in different devices at the terminal and find the current in the parallel resistor. I...

I saw a thread recently started about the AP Calc test. So, is anyone else out there taking any of the AP physics tests (i.e. B or C)?
