The Hamiltonian method - Harvard University
scholar.harvard.eduhow useful the Hamiltonian formalism is. Furthermore, since much of this book is based on problem solving, this chapter probably won’t be the most rewarding one, because there is rarely any beneflt from using a Hamiltonian instead of a Lagrangian to solve a standard mechanics problem. Indeed, many of the examples and problems

theory.fi.infn.itSo, the transformed Hamiltonian is precisely the moving-frame Hamiltonian we had guessed on the basis of the equivalence principle. Let us now return to classical mechanics. From now on we derive our Hamilton’s equations from the moving-frame Hamiltonian, which we simply denote by H. The Hamilton’s equations read: 8 >> < >>: _ = @H @p = p ...
