The constant of motion of a free fall body

  1. Oct 8, 2008 #1
    1.what are the the constants of motion of a free fall body(treat this as a one-dimension motion,so there are two [independent] constants of motion )?

    2.are they initial velocity and initial displacement?

    3.and i know the total energy(T+V) is one,but they are not independent with the initial velocity and initial displacement, isn't it?

    4.so i means can we just treat the initial velocity and initial displacement as constants of motion ?

    5.if we can,do these constant of motin (initial velocity and initial displacement) correspond to some symmetry of the system (free fall body)?
