This is a general question. When evaluating Poisson brackets, can we assume that [tex]H = p^2/2m + V[/tex]?

A Poisson Bracket is a mathematical operation used in classical mechanics to describe the relationship between two physical quantities, such as position and momentum.
To evaluate a Poisson Bracket, you first need to determine the equations of motion for the two quantities involved. Then, you substitute these equations into the Poisson Bracket formula and simplify to get the final result.
This formula represents the total energy of a particle in classical mechanics. H is the Hamiltonian, which is the sum of the kinetic energy (p^2/2m) and the potential energy (V) of the particle.
Poisson Brackets are used to describe the evolution of physical systems in classical mechanics. They help determine the equations of motion and can be used to calculate important properties such as energy and angular momentum.
No, Poisson Brackets are only applicable in classical mechanics. In quantum mechanics, the equivalent mathematical operation is the commutator, which has a different formula and meaning.
