Let's compile a list of formulas used on the SAT Physics test :)

Test Preparation SAT Subject Test Preparation
1

<p>F = ma (F: force; m: mass; a: acceleration)</p>

<p>F = wa (w: weight)</p>

<p>w = mg = F (g: gravity)</p>

<p>KE = 0.5 m v^2 (KE: kinetic energy; v: velocity)</p>

<p>KE = mgh (h: height)</p>

<p>F = (k q1 q2) / r^2 (k: use it as a constant, such as 1, because you never really need to exactly calculate this value; q1: charge at point 1; q2: charge at point 2; r = distance)</p>

<p>W = Fd (W: work; d: displacement)</p>

<p>A x B = ABsin(theta)</p>

<p>A o B = ABcos(theta)</p>

<p>V = IR (V: voltage; I: current; R: resistance)</p>

<p>F = qvB when velocity is moving perpendicular to the magnetic field (B is the strength in "T" units)</p>

<p>P = W/t = Fd/t = Fv = mgv (P: power; t: time)</p>

<p>P = IV</p>

<p>H = Pt (H: heat)</p>

<p>V = kq/r</p>

<p>v = f(lambda) (f: frequency)</p>

<p>That's all I've got so far. Let's all contribute! Hopefully when we come up with a big enough list we can put things in categories and understand how each one is used.</p>

2

<p>Just memorize the AP Physics B equation sheet.</p>

3

<p>Not all of the Physics B equations are used on the SAT 2 though. Like a lot of fluid/thermal stuff and even some E/M stuff.</p>

4

<p>^Fluids, thermal, and E&M from B are tested on the SAT II.</p>

<p>I remember from my test in June 2010 that one of the questions required you to know that U=(3/2)RT, which I conveniently forgot. -___-</p>

<p>I have a list but its in picture format not text. Is there anyway I can upload it as a document?</p>
