Motion in 1D m d^2x(t)/ dt^2 = - V ' (x(t)) * V(x) particle moving in 1D x with under the influence of a potential. * X(t) V' derivative of V w,r,t to argument this is newton's equation and is difficult to solve cause it's not an linear equation. Derivative of a potential if potential goes left then it's minus. V' is the derivative of V with respect to argument. * But Quantum mechanics is linear! Schrodinger equation. i h bar partial derivative with respect to time of psi is eqaul to H hat of psi, where H hat is c...
