MCAT Formula Cheat Sheet
Physics
Kinematics: v = v0 + at, d = v0t + 0.5at^2, v^2 = v0^2 + 2ad
Forces: F = ma, fk = mu_k*N, fs <= mu_s*N
Work/Energy: W = Fdcos(theta), KE = 0.5mv^2, PE = mgh, P = W/t
Momentum: p = mv, delta_p = F*delta_t
Circular Motion: Fc = mv^2/r, ac = v^2/r
Waves: v = f*lambda, I = P/A, beta = 10log(I/I0)
Optics: f = r/2, 1/f = 1/o + 1/i, M = -i/o
General & Organic Chemistry
Ideal Gas Law: PV = nRT, Density: rho = m/V, Molarity: M = mol/L
Heat: q = mcDeltaT, DeltaH = H_products - H_reactants, DeltaG = DeltaH - T*DeltaS, DeltaG = -RTlnK
Electrochemistry: DeltaG = -nFE, Nernst: E = E° - (0.0591/n)logQ
Acids/Bases: pH = -log[H+], pOH = -log[OH-], pH + pOH = 14, Ka*Kb = Kw = 1e-14
Kinetics: [A] = [A0]e^(-kt), rate = k[A]^x[B]^y, Keq = [products]/[reactants]
Biology & Biochemistry
Enzyme Kinetics: v = Vmax[S]/(Km + [S])
Genetics: Hardy-Weinberg: p^2 + 2pq + q^2 = 1, p + q = 1
DNA/Protein: DNA -> RNA -> Protein, pI = (pKa1 + pKa2)/2
Constants
g = 9.8 m/s^2, R = 0.0821 L·atm/mol·K or 8.314 J/mol·K
F = 96485 C/mol e-, k = 1.38e-23 J/K
