<p>Can someone please list all of the equations that we NEED to know???</p>
<p>Time to pull out my self-made flashcards.</p>
<p>I would say:</p>
<p>Kinematics (the big four/five): Vf = Vi + at, etc
KNOW the graphs of motion
Momemtum = mv, impulse is change in momentum (but not over time!!)
Work = Fd
V = IR
F = ma
Fg = Gm1m2/r^2
Fe = Kq1q2/r^2 = qE
Fb = qvB
Fc = mv^2/r
V = Ed or qW, Work = qV, Power is IV
C = q/v for capacitance
v = wavelength times frequency for waves
q = smt (heat)</p>
<p>Are the essentials. Good luck!</p>
<p>omg thank you SOO much!!!!!!!!!!!!!!! ^.^</p>
<p>words cannot express my gratitude!!!!</p>
<p>What do the following equations mean?
Fc = mv^2/r
C=q/v</p>
<p>Btw.. I'm gonna add some more</p>
<p>m = -Si/So
1/Si + 1/So = 1/F</p>
<p>P = (change)T/V</p>
<p>Oh ok I looked it up Fc is the centripetal force... ok ok...</p>
<p>Yep, I forgot the mirror equations but they are essential.</p>
<p>C=q/v is the capacitance equation. C is also = Ke times A/d</p>
<p>And I'm not sure what formula you're referring to for the last one, P = T/V?
Ohhhh... nvm, that's for a gas right?</p>
<p>I found 345807348759 equations in Modern Physics section; should I just ignore them then? (I know I should memorize the basic relativity/quantum theory formulas though)</p>
<p>Is electromagnetic induction/magnetism significant?</p>
<p>For Modern, know:</p>
<p>Mass/Energy Equivalence: E = mc^2
Relativistic Factor: (1 - v^2/c^2)^1/2
Energy of a photon: E = hf or vh/wavelength
KE for Photoelectric Effect: KE = E - Work Function </p>
<p>Also, since the CB book said Chaos Theory and Superconductivity might be tested, here are the basic points of both:</p>
<p>-Superconductivity: When the conductor has NO resistance and NO interior magnetic field. This often occurs in supercooled metals. This is how you can get a magnet to hover over a current-carrying superconductor.</p>
<p>-Chaos Theory: Basically, the idea of Chaos theory is that it is impossible to make long-term predictions of a system, because it is impossible to make infinitely precise measurements of the system. (In order to make infinitely precise measurements, you'd have to have a measurement machine that had an interface that could display an infinite number of digits). Also, the degree of accuracy of measurements and input used when calculating long-term effects of a system makes no difference to the accuracy of the prediction. Key term - Butterfly effect - the idea that the flap of a butterfly's wings can start the disturbances that build into a tornado.</p>
