It depends. If your knee is touching the ground, or if the ball is, you are considered "down by contact". If both the ball and your knee are off the ground, you are still able to get up and run. (This has happened numerous times with players falling over an opposing player, landing on their feet and continuing on)
The runner is considered down when either a: His forward progress stops or b: any part of his body other than his foot or hand touches the ground AND he is touched by a player of an opposing team. There is no "down by contact" in college football. That's only in the pros. When a college player goes down he cannot get up and continue running, period. He does not have to be touched by an opposing player to be considered down.

no because once the football player has lost all of his forward momentum the refree will mark the ball down there.
No. In Professional Football, in order to be "down" a receiver has to be tackled or in your scenario touched by a defensive player while on the ground.
