How Many Objects Can Be Juggled (1997) | Hacker News

2018-5-22 · For a given ball, as it falls and picks up speed, the air resistance goes up, becoming more and more effective at countering the gravitation force. This puts an upper limit on how fast the ball can fall--the so-called "terminal velocity". This is the velocity where D(v) = -gm. Note that for balls with larger mass, terminal velocity will be higher.
