A Virgin Galactic flight provides a clear example of suborbital mechanics. The video follows carrier-aircraft release, rocket-powered climb, engine cutoff and weightlessness, apogee, feathered reentry and gliding, then explains why suborbital speed is far below orbital velocity and how the 50-mile and Kármán-line definitions of space arose.
