Basic Physics Course with MATLAB's Symbolic Toolbox and Live EditorAnimation 1: Action field of the Kepler/Coulomb problem
The action field S is shown above the x-y plane. The time dependence is animated. We see a screw that moves down (S= ... -Et). The speed of the devaluation movement is the energy E. To make it clear that it is not a rotation, the value of the action field S is additionally color-coded. Further details can be found in Chap03_2 |
