Homework Help: Oscillator basic question

  1. Aug 27, 2005 #1
    Question about oscillator (Simple Harmonic Motion)

    Hi, I just have a basic question about oscillators. If we are only given the initial position, can we still determine the amplitude and phase constant?
    I think we can't because we would still need to know the angular frequency (k and m needed as well) and whether or not the system starts with an initial velocity of zero. Am i thinking in the right direction?

    no, with just initial position, you can't determine both A and phi.
