Abstract

In mathematics and classical mechanics, the Poisson bracket is an important 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. In this work we study some examples from the classical mechanics of particles and apply mathematical method for building the equation of motion. In the present paper Poisson Brackets and their properties are presented, by using Poisson brackets and their properties we calculate some brackets. We use the Poisson bracket with Hamiltonians to express the time dependence of a function u (t), the main idea Taylor series is taken as the required solution for equation of motion using the properties of the Poisson Brackets, We have examined examples from the classical mechanics to illustrate the idea such as motion with a constant acceleration, simple harmonic oscillator, freely falling particle. The solutions are compatible with what is known in classical mechanics. The work is fundamental and sheds new light onto classical mechanics. Poisson brackets are a powerful and sophisticated tool in the Hamiltonian formalism of Classical Mechanics. They also happen to provide a direct link between classical and quantum mechanics.

Introduction

Poisson brackets are of great importance in physics: An important binary operation in Hamiltonian mechanics, play a central role in Hamilton's equations of motion, distinguishes a class of coordinate transformations (canonical transformations), very useful tool in quantum mechanics and field theory. [1, 2]. Poisson brackets are of great importance in physics: An important binary operation in Hamiltonian mechanics, play a central role in Hamilton's equations of motion, distinguishes a class of coordinate transformations (canonical transformations), very useful tool in quantum mechanics and field theory. A technique that uses the Poisson bracket is supposed to allow us to derive all the differential equations of motion of a system from the just one piece of information, namely from the expression of the total energy of the system, i.e., from its Hamiltonian [3,4,5]. The Taylor series of a function is an infinite sum of terms that are expressed in terms of the function's derivatives at a single point. The main idea Taylor series is taken as the required solution for equation of motion using the properties of the Poisson Brackets, We have discussed physical applications and treated some examples with Taylor series using Poisson brackets
