Ap physics Definition and 343 Threads

Recently my AP Physics class had a test on energy. The following is one of the questions verbatim from the test. I just can't work out the problem to any of the choices, let alone the "correct" choice. The problem is: Movers want to set the ramp of their truck so that the work they do against...

hi, I'm in the AP Physics for high school, and I've been wondering about an idea about constructing a lab... i need some things i can test, because the assignment is to create a lab on your own w/e it is... (kinematics, thermo, w/e AS LONG AS it's not electrical or uses wires)... any suggestions...

My midterm is basically going to simulate a real AP exam. So I was wondering if anyone knew where I can get previous year's AP physics C Mechanics exams so I can practice. Thanks a lot.

This problem is KILLING ME! The drawing shows a baggage carousel at an airport. Your suitcase has not slid all the way down the slope and is going around at a constant speed on a circle (r = 10.8 m) as the carousel turns. The coefficient of static friction between the suitcase and the carousel...

I'm a high school sophmore. I have an A in AP Calculus AB and a B in AP Chemistry. Next year, I want to do an Independent Study on AP Physics C since my school does not offer AP Physics C. I will also take AP Calculus BC(my school offers this)next year. I have had no previous high school level...

Hi everyone, I need some advice on what to do about my AP Physics course. Last year when I was taking my CP Physics course as a junior in high school I got sick (am still battling now) and I self taught 2/3 of the material because I wasn't able to attend school regularly until the last...

I'm taking AP Physics C at school and plan on taking the AP test in May. I want to get my AP prep. book early so I can follow along with the review in the book alongside of my studies at school. What has anyone found to be the best review book? (i.e. Barron's or Princeton Review) I know that...

Does anyone know where to get good lecture notes for either AP Physics B or AP Physics C - Mech & E&M? Or a review packet of the curriculum? Thanks for your help!

Hi, I'm new to this forum and I hope I can find some help with my AP Physics class! I find the subject really interesting, I just have a hard time applying it. Also, I don't really know the people in my AP Physics class, so it would be awkward to ask them for help. Anyway, last week we did...

Anybody know any good books for AP Physics B and AP Physics C. Also, does anyone know of any good books for the Physics Olympiad? Thanks.

I have to do a project for my AP physics class. It’s due in about a week and I have no clue what to do for it. I’d like to do something that has to do with electricity but I’m open for any ideas. If anyone has done or knows about a fun physics experiment, please tell me about it. It can’t be...

I have been working on the 2005 AP Physics B Free-Response Questions from Form B. Question 3 is giving me a lot of difficulty, and I am not sure if i am going in the right direction. The question can be found here...

Can anyone provide advice for this? We will be putting them in the school's pool and racing them. But I really want some advice. (1) Formulas to find if the boat will float or sink (we'll be able to make measurements and stuff). (2) Plan ideas. (3) Stuff to focus on in building. We...

Does anyone have the answers with work for the 2005 AP Physics B free response section? anything would be greatly appreciated.

I'm taking the AP Physics section B test in about an hour (good luck to anyone taking that), and I have a relatively simple question to ask that I hope I can get answered in that time. In torque, why was torque established to be positive in the counterclockwise direction and negative in the...

Hi guys, I need help with the following problem I couldn't figure out: 1) A block of mass 2 kg slides along a horizontal tabletop. A horizontal applied force of 12 N and a vertical applied force of 15 N act on the block. If the coefficient of kinetic friction between the block and the table...

Which of the three circuits below contains resistors that are neither in series nor parallel and why? http://jon8rfc.homeip.net/uploader/uploaded/phys.gif Currently in AP Physics, so I know have a lead on the question. The first one would be my first guess, because I'm not sure how...

Ap Physics Heeeeeeeeeeeeeelllllllllllllllppppppppppp! ! Please! Hi, I really need help on the following questions and would appreciate it if someone could ASAP! Thank you! 1) a bullet of mass m is moving horizontally with speed v when it hits a block of mass 100m that is at rest on a...

Hey I am in 12 grade but this is advanced placement so its college level... Anyways i could use some help on this problem i have A 5kg ball initally rest at the edfe of a 2-meter long, 1.2 meter high frictionless tavle, as show above. A hard plastic cude of mass .5kg slides across the table...

My Teacher gave me an interesting problem in AP Physics which seemed simple at first but has me going insane. The problem was what would happen to the potential energy contained in a spring if 0.2 kg was added to the original 0.2 kg on the spring, which stretched the spring 5 cm. The...

AP PHYSICS PROBLEM...i forgot the formula, someone help me solve! This won't take lon Light of frequency 6.0 x 1014 hz strikes a glass/air boundary at an angle of incidence, ø1. The ray is partially reflected and partially refracted at the boundary as shown. The indices are shown. (a)...

We're doing some coupled motion stuff in my AP Physics class and this is my second year of physics because we didn't do it last year in honors and I'm getting a bit lost with this. Does anyone have any links or explanations to help me understand this a little better?

ok I've been trying to figure out this problem for about an hour :/ A golfer drives a ball at an angle of 30 degrees with the horizontal at an initial speed of 60m/sec. How high does the ball rise? ok I am pretty sure this is a projectile problem. Vf=0(?) Vh=52m/s Vv=30m/s (i used sin...

I am doing a sort of independent study of AP physics and I ran across a question that I am pretty sure requires either the law of sines or the law of cosines but I can't remember them, can anyone help me out? Thanks, HT

Hey guys. I am not sure where to post this and my knowledge of Physics is very lacking due to very imcompetent teachers at my school, and my lack of motivation to teach myself. That being said, I am going to be a senior in high school and I am planning to take AP Physics B. Problem is...

How did everyone do? :)

Hey everyone... since the AP Physics C Exam is coming up next monday I was looking for old exams online (multiple choice exams) to study from. I've been searching for days and haven't come up with anything. Does anyone know where I can find old multiple choice sections of the AP Physics C Exam.

hello, in lieu of the upcoming ap exam, I have been studying old free response questions from ap exams. I have a question about this one A crash test car of mass 1000kg moving at constant speed of 12m/s collides completely inelastically with an object of mass M at time t=0. the object was...

I'm in standard physics junior year of high school. I really like physics but am wondering if I'll be able to handle AP without pre-calculus (which I'm taking next year also).

A billiard ball has mass M, radius R and moment of inertia about the center of mass Ic=2/5MR^2. The ball is struck by a cue stick along a horiontal line through the ball's center of mass so that the ball initially slides with a velocity Vo. As the ball moves across the table (which has a...

I'm doing an independent study in AP Physics, and am having a lot of trouble with the following problem: "To stop a car, first you require a certain reaction time to begin braking; then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car...

Should AP Physics questions go under K-12 or college level? I mean we use a college textbook so I am assuming the material matches that of some colleges - but we are still in a high school setting.

I'm going to be a high school senior next year and am planning on majoring in physics at college, unfortuantely our school does not offer an AP Physics course, they only offer one general physics course which I have already taken and which failed to teach me anything. But, since I am majoring in...
