| 31. | Notice the Routhian replaces the Hamiltonian and Lagrangian functions in all the equations of motion.
|
| 32. | The geodesic equation of motion can alternatively be derived using the concept of parallel transport.
|
| 33. | Producing the corresponding equations of motion of low-energy physics.
|
| 34. | Then the equations of motion are of the form
|
| 35. | This differential equation is the classic equation of motion of a charged particle in vacuum.
|
| 36. | Still, the equations of motion follow from Hamilton's principle
|
| 37. | This produces severe restrictions, because the equation of motion has to be a sensible one.
|
| 38. | The equation of motion for this SDOF is
|
| 39. | The resulting equation of motion is as follows:
|
| 40. | Setting each of the summands to 0 will eventually give us our separated equations of motion.
