A simple interpretation of Hamiltonian mechanics comes from its application on a one-dimensional system consisting of one nonrelativistic particle of mass m. The value H ( p , q ) of the Hamiltonian is the total energy of the system, in this case the sum of kinetic and potential energy, traditionally denoted T and V, respectively. Here p is the momentum mv and q is the space coordinate. Then H = T + V , T = p 2 2 m , V = V ( q ) T is a function of p alone, while V is a function of q alone (i.e., T and V are scleronomic).
