Degrees of freedom of an oscillator in an Einstein solid

  1. Jun 14, 2012 #1
    I was reading through a book on statistical physics when i came across this sentence: "An Einstein solid has two degrees of freedom for every oscillator."

    How is this possible? I picture an oscillator (ex. mass on spring) to move only in one dimension, thus one degree of freedom. Where does the second degree of freedom come from?

    But they have both potential and kinetic energy. You can choose both the length of the spring and the velocity of the vibrating particle, and the energy depends on both.
