There are two main descriptions of motion: dynamics and kinematics. Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations. However, kinematics is simpler. It concerns only variables derived from the positions of objects … Web26 de ago. de 2015 · 1 Answer. The Liouville equation for the N particle system, describes the time evolution of the phase space N-particle probability density, which you can also neatly rewrite with the Liouville operator: fN(t) = e − iLtfN(0). Now almost always we're interested in a smaller subset of only n particles, for which then we have to define a …
