If anyone has any experience with this, it'd be helpful if I could have the equations I'll be needing for the test. I'll probably know how to use them, I just don't have them all completely memorized. Thanks.

For those of us Edison who are in different countries and have slightly different curriculums, what sort of physics is this SAT on?
-
Not entirely sure >.> It's stuff that you can learn in year one of Physics. But there are certain things I've learned that I need and others that I don't. There are also some things that I haven't learned that will be on it (like relativity). From what I understand, the equations aren't on the test. If they were, I could probably answer all of the problems just using them without worrying about this. If it's just the simple ones, I'll be able to remember them. But I know there are some different distance/velocity/acceleration/time equations that I don't have memorized. However, now that I think about it, those shouldn't be too hard to derive. Looks like I can find the equations on sparknotes.

Well i am going final year Physics at high school. For my physics i need to know the constanct acceleration formulas, circular motion, forces, energy, etc. Physics itself as you probably know is simply just concepts and then applying those concepts to solve equations.
-
I have a few different equations for calculating velocity/acceleration/displacement. I don't know if they'll help you, but I'll post them anyway. Most are just derived by rearranging others.
Key
a - acceleration
u - initial velocity
v - final velocity
t - time
s - displacement
a = v - u
t
s = ut + ˝at˛
s = ( u+v ) t
2
v˛ = u˛ +2as
Those are the equations I have been taught in my first year of Mechanics and Physics, seeing as I have only done 1 year I haven't come across any more, hopefully they'll be helpful, probably not :P

Am I too late to help you? I can help you with prettymuch anything you may need through a high school course. (I had the best teacher EVER) "The Granddaddy Equations", a.k.a., the three old well known ones having to do with final/initial velocity and acceleration, Igor touched on them in the previous post, then there's centripital acceleration, forces (can help with friction problems, but am rusty), index of refraction stuff (apparent depth in liquids is really cool), the lensmaker equation, the lens-mirror equation, object/image position with lenses/mirrors, ray tracing, doppler effect equations for light and sound (yes, they're slightly different), interference patterns, etc. I don't want to write it all out unless it could help you, so if I'm not too late, tell me. If not, and assuming that you don't already know everything that I just mentioned, I can try to draw out diagrams, explain things, etc. School just got out for me, so I returned my textbook, but I remember mostly everything. (at least I think I do... :P)
P.S. - I'm a physics nerd. :drool: :drool: :drool: :drool: :drool:

Already took it, but thanks. I'll probably get at least a 750 on it. And for the Math II I'll get at least a 790 is my guess. Too bad I won't get to see it till I return from my trip.

If it was anything like my year 1 Semester 1 physics the topics we covered were
Particle Physics
Cosmology
Mechanics
Special relativity
Thermodynamics
Wave Mechanics
Nuclear Physics
More subjects for second semester first year stuff
We carried on in understanding the equations and how they were developed mostly this year with some new topics like general rel etc, however iam guessing you probably already had the exam by now :P
-
Results are in. 800 on Math II and 750 on Physics.
-
Well done Edison!
-
Woah, great marks Ed!
-
F= M x A
Force = Mass x Acceleration
I just learnt about this stuff sorry im so late
PS WTG
