Answer to Question #156497 in Classical Mechanics for Sneha

Question

What are poission bracket.

Answer 1

The Poisson bracket is binary operation in Hamiltonian mechanics, playing a central role in Hamilton's equations of motion, which govern the time evolution of a Hamiltonian dynamical system. The Poisson bracket also distinguishes a certain class of coordinate transformations, called canonical transformations, which map canonical coordinate systems into canonical coordinate systems.
