Analytical Classical Dynamics: An intermediate level course

    Lagrangian(L) and Hamiltonian(H),
    Dear Greg I am studying the L and H.

    If kinetic energy(K) and potential(U) are given it seems that L=K-U.
    Hamilton defines (p_i, dot q_i being components of momentum, resp. velocity in i'th direction): H=sum p_i*dot q_i - L and it appears that for a conservative situation the Hamiltonian becomes H=K+U. With conservative one means usually U is a function of coordinates only.

    Do you think that this system would work for a mass-velocity relation? So a momentum which a changeble mass as a function of velocity v=Sqrt(sum (dot q_i)^2)?
