Yeah, the force of gravity depends upon the mass. And the 747 has A LOT higher mass as well as mass-to-air-drag ratio than the ping-pong ball... Imagine Galileo dropping a 747 versus ping-pong ball off the leaning tower... heh, heh...


Hey, that's another good calculus model. Compute terminal-velocity as a function mass-to-air-drag. Maybe model a piece of plywood falling on edge versus falling flat. Skydivers know all about this too well..
