 What is the formula for frequency? f = 1/T Rotational S = ? S = R(theta) Vt = ? R(omega) At = ? R(alpha) alpha = At/R Ac = ? V^2/R Hooke's Law states: Stress is proportional to strain. Frequency: F = 1/T W = W = 2(pi)(f) = 2(pi)/T = square root of K/M Uspg Uspg = 1/2K(delta)s Work Engergy Theorem Ki + Ui + Wi->f = Kf + Uf SHM x(t) = x(t) = Acos(wt) -> Xmax = A v(t) = v(t) = -Aw sin (wt) -> Vmax = Aw A(t) = A(t) = -Aw^2 cos (wt) -> Amax = Aw^2 Gravitational Fgrav = Fgrav = (GmM)/r V^2 = v^2 = GM/r Kepler's Law: GM/4pi^2 = r^3/T^2 g = (g = gravity on a planet) g = GM/R^2 Circular Motion S = S = R(theta) V = V = R(omega) A = A = R(alpha) Kinematics Vf = Vf = VoAt Vf^2 = Vf^2 = Vo^2 + 2a(delta S) Sf = Sf = So + Vot + 1/2at^2 Energy Kt Kt = 1/2mv^2 Kr Kr = 1/2Iw^2 U = ?
