Coupled oscillator

  1. May 3, 2010 #1
    Hi, this is a fairly basic part of the whole coupled oscillators area, but I don't really get it.
    My problem is with the equations of motion of a coupled oscillator:
    F_A=-kx_A -2k'x_A
    m\ddot x_A = -kx_A -k(x_A-x_B)

    Everywhere I've read seems to take it as intuitive, but I don't see how.
    Can someone explain it please?

    It's been a while since I did this sort of thing, but might you be missing a term or two? Those equations don't look quite right. (Also, just to be clear, what is each of your variables supposed to mean?)
