What is the difference between orbital velocity and escape velocity?
Orbital velocity keeps a satellite in a circular orbit; escape velocity (√2 times larger) lets it leave gravity forever.
Orbital velocity keeps a satellite in a circular orbit; escape velocity (√2 times larger) lets it leave gravity forever. A reliable way to keep them apart is to focus on what each one is defined by, not just the similar-sounding words.
