The B exam is the equivalent of a full year of algebra based physics.Originally posted by axon
Hey confuted, I never took Phys AP in high school...is it calculus based, or algebra? Because I'm hearing both answers from different people. Some had calc some had alg...my school in the college of engineering only accepts calc based phys AP exam, but some schools accept either or
There are two C exams - E&M and Mechanics. Each is considered the equivalent of a semester of calculus based physics.
Away.
You still have to memorise a lot of equations since in many instances it is impractical to derive them from base principles.physics is better and no memorizing
thats true...but at least allmost everything makes sense...and if you do forget an equation, it is a sintch to derive it! Thats why I will take any physics over any chemistry all the time.Originally posted by Clyde

Well, on the purpose of memorization, have you tried chanting? no, not the religious kind, i mean chanting the terms/ions/molecules/etc. and then the definition/answer/etc.. It has done wonders for me in college, as instead of having to reread the book at mid-term/finals time, i can look at just a list that has the terms and recite the definitions from them by heart(now, understanding things is different, and requires actual solving problems based on them, as well understanding how different things work together).
Well i'd say that chemistry makes sense too, it's just that you don't get taught much of the reasoning behind stuff untill later (or unless you go looking).thats true...but at least allmost everything makes sense...and if you do forget an equation, it is a sintch to derive it! Thats why I will take any physics over any chemistry all the time.
In terms of physics it depends what level your at i guess, it gets harder and harder and longer and longer to derive equations from base principles as the equations get more complex, what that means is that in practice you need to know the equations because you cannot afford to waste time in exams deriving them.
Well, I'm only on Phys 2; E&M calculus based, and it is fairly simple still. Mechanics calc based, was a joke really...but that is probably because I like physics, because it is one of the drop courses. There were 4 sections with about 100 students each in mechanics, and about 300 got a 'D' or lower. But the physics program at my school is quite famous in being extra difficult. It is worth 4 credit hours, yet I'm in class 8 hours a week!!! Next semester its Phys 3 ' modern physics', this is the outline: "Special theory of relativity. Particle-wave duality. Uncertainty principle. Bohr model Introduction to quantum mechanics. Schroedinger equation. Hydrogen atom. Many-electron atoms. Introduction to nuclear and particle physics." - looks interesting.
The professors are trully horrible, but this is done on purpose in courses such as Calc 1 - 3, Chem 1 -2, and Phys 1 - 2. School's simply don't have space for all the engineering students in the more major based technical courses so they eliminate weak links, so to speak.
I'm taking Linear Algebra now, with the same professor who tought me Calc 1; at first I was horrified to see him again, but what a different person he is! In calc 1 he simpy was terrible, he just did what he had to, to cover the material in the book, again about half the people failed. Now, he is great!

I write the schrodinger equation wherever i find condensation, all the mirrors and windows of my house have multiple (albeit faded) copies on them. When i was living with a theology student he used to ask me what it meant... now that's a challenge: explain the S.E. to someone who hasn't taken science past school.Next semester its Phys 3 ' modern physics', this is the outline: "Special theory of relativity.

Still looks like some good stuff there, if you haven't come across Q.M. before it will blow your mind and redefine the way you think about how nature "ought" to behave.
So you're a 1st year undergraduate, and are going to major in physics?
No actually I'm a third year, undergrad, majoring in CS engineering, with math and physics minors. I wanted to get done with all of calculus before taking any physics; things just make more sense once you have a solid mathematical background.

how ironic..hehe. I used to be obssesed with fractals, and coming up with simple ways to draw then by hand.
Anyone ever obssesed with pi? has anyone seen the movie entitled "Pi". If not, it is worth a look see.

Answering both your questions:
from memory: 3.1415926535897932384626
And yes, I've seen the movie.
Away.
im taking ap physics. its mostly algerbra. if you understand the concepts then the math comes easy.
Yes, but algebra based phys is nothing like calc based phys. You can't do the "cool" and interesting things without calc...maybe not so much in mechanics, but deffinately in E&M.Originally posted by the Wookie

Hey confuted, if you liked 'pi', check out "Requiem for a dream"; it is by the same director, and it is freakin amazing. Marlin Waynes (sp?), is one of the actors in it...at first I thought the movie will be a joke if he is playing in it...but as it turns out, he gave a damn decent performance. Jennifer Conely (sp?) is also in the film as well. The movie is quite graphic; it tackles many themes that other directors would not dare touch. If you know anyone who does drugs, and you want to help them get over their habit...have them watch the movie - sober of course. It could change their life.

I already watched that tooGood ol' heroin addicts. It was a bit strange, and actually rather disturbing.
Away.
Hmm... I distinctly remember doing plenty of surface integrals and the like when I took AP Phys C. There wasn't anything nearly that nasty on the actual exam though.
In Newtonian mechanics and E&M, it is definitely not too bad (from a relative standpoint) to rederive things, but it can be a pain. I can't speak about quantum mechanics, but I do know that rederiving some equations for fluid dynamics would be a disaster on a test.
Chemistry, at least AP Chemistry is not that bad really. All you've really got to do to find your equations is use dimensional analysis, and make sure to remember the units of any constant. Some idea of the physics behind chemistry definitely helps, but is not strictly necessary to get the equations.
Now, if there was a nice formula for AP English Lit, I'd be set.

thats the difference between taking Phys in hs vs college...in college the exams are "nastier"!Originally posted by Zach L.

confuted: I really liked the way the director showed the whole process of the preparation and injection of the drug...really brilliant, and super effective! I saw many others try to do a similar thing in their movies, but no one comes close. I hope that the director, Darren Aronofsky, will make another movie. I really have to say that both of the movies we have been discussing are in my top ten best.

I can imagine. The tests during the year were rather "nasty", but the AP itself wasn't. I can imagine college level would be pretty bad as well.
