SUMMARY
This discussion focuses on programming orbit dynamics in MATLAB without explicitly using mass. The user seeks to calculate kinetic energy, potential energy, and total mechanical energy at various positions in an orbit using the equations for kinetic energy (0.5mv²), gravitational potential energy (-GMm/r), and total mechanical energy (E = k + p). A key solution proposed is to set mass to a unit value (1 unit) to simplify calculations while maintaining the integrity of the energy equations.
