Orbital Energy, Velocity & Escape Speed: Foundations

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.

Orbital motion is governed by the exchange between kinetic energy and gravitational potential energy.

supported

A spacecraft moving outward against gravity trades kinetic energy for gravitational potential energy and slows unless additional energy is added.
