The Hamiltonian describes the energy of a physical system as a function of its canonical coordinates and momenta :

It drives the time evolution of the system (see Hamiltonian mechanics).

In quantum mechanics

It is also important in quantum mechanics as it appears as an operator, the Hamiltonian operator.
