Physics c Definition and 90 Threads

imagine a person pushing a 10Kg cardboard box with 20N of force toward a 5Kg cardboard box, with the second law we can calculate it is moving at 2ms/s acceleration toward the 5Kg box, relative to the 10Kg box we can say the 5Kg box is moving toward the 10Kg box with 2ms/s acceleration with a 10N...

For this one, am i supposed to use W = change in KE where i calculate work as ((F - friction - mgsintheta) times d), or am i supposed to do the change in -mgh plus Wfriction = change in KE (where if it is in this case, is the friction going to be a negative number?)

I'm guessing this question can be solved using the law of conservation of momentum Vi = 5 m/s (5 m/s) M = (4.33 m/s) cos30 M + V sinθ M I don't know what to do after this... I'm also not sure if I use the sin and cos correctly.

What are some of the hardest concepts to learn in AP E&M? I am going to prepare for the exam with my previous physics teacher. I am currently a senior enrolled in AP Calc BC, and I already took AP Mechanics.

I'm currently taking a course where we are working to teach older physics concepts and combine them with calculus. I was assigned to work on teaching a unit about energy; for the most part, it stays relatively consistent and can be solved algebraically. Another topic in this unit is Potential...

https://apcentral.collegeboard.org/pdf/ap-2020exam-sample-questions-physics-c-mechanics.pdf For 1 b) how did they get that equation? Is it wrong?

I am attempting to solve part b of this question. I start with the equation A=L^2/4 and I get dA=L/2(dl). Next I find dA/dt=L/2(dL/dt) and I realize dL/dt=v. Thus I get -d(flux)/dt=-BLv/2. Finally, I use emf/R=I. I get -BLv0/2R=I. However, the answer is BLv0/4R=I. I understand dA is supposed to...

To the people who took AP Physics C in high school and then took the introductory Calc-based physics sequence in college; how does Physics C compare to the Intro Sequence?

I have decided to go home schooled for my last two years of high school and I am trying to make a curriculum at the moment. Do any of you know a good resource for this? It has not been too hard to find a physics 1 or 2 course, but calculus based physics courses have been pretty sparse. So far I...

Hi, I know I have asked a similar question before but I now have more information. I have been communicating with the AP physics teacher at my high school. I have really been looking to challenge myself with science (which I can't do this year; I have a 100% in honors chemistry, a mostly 10th...

I was wondering if there were any good online resources for AP Physics C with notes, practice tests, etc.

Hi, I will concurrently attend high school and take Calculus 1 and 2 Honor in community college next year. I know that Physics C is calculus-based course and I have already known it. I'm major in Engineer and want to know if I could skip Physics B and move to C instead. I hear that Physics B is...

I am a current High School senior intending on majoring in Physics in college. Last year I took IB Physics SL and got a 4 on the test but kept my head above water on all the unit tests. I'm currently taking AP Calculus BC and am doing very well. I have exhausted all other science classes in my...

Firstly, let me talk about my BC exam situation first and then the Physics C exam secondly. I just recently downloaded a PDF full of released BC exams from 1969 to 1998. Is there any PDF for a fully released BC exam from last year(2015)? What is the best textbook that is oriented towards this...
