Orbital Energy, Velocity & Escape Speed: Physical Mechanisms

Orbital motion is governed by the exchange between kinetic energy and gravitational potential energy. Orbital energy calculations determine launch requirements, transfer orbits, capture burns, reentry trajectories, and interplanetary mission design.
