Solving hamiltonian equations
WebThe dynamics are determined by solving N second order di erential equations as a function of time. Note: coordinates can be the vector spatial coordinates r i(t) or generalised coordinates q i(t). David Kelliher (RAL) Hamiltonian Dynamics November 12, 2024 5 / 59 WebThe s equations ∂ f / ∂ α i = β i can then be used to find the q i as functions of α i, β i, t. To see how all this works, it is necessary to work through an example. A Simple Example of the Hamilton-Jacobi Equation: Motion Under Gravity. The Hamiltonian for motion under gravity in a vertical plane is. H = 1 2 m p x 2 + p z 2 + m g z ...
