It is a fumble when the ball is bobbled and a touchback when it goes out of the endzone. It is placed on the twenty yard line.
If a ball is intercepted in the defended endzone (the endzone the defense is trying to , it is considered a touchback and the ball will be brought out the to twenty yard line, just like a kickoff that is fielded in the endzone. If the intercepting player spikes the ball, he might get called for a penalty, but only if he is, in the eyes of the official, celebrating excessively. If the ball is intercepted by the defense in the opponents endzone it would be a touch down.
If a player fumbled the ball into and out of bounds in his own endzone after making a pass interception on his 1 yard line, it is an automatic safety.The impetus is on the player who fumbled.
If the ball goes into the endzone due to an offensive player or action (taking the snap into the endzone, running it back into the endzone, etc...), then the play results in a safety. If the ball goes into the endzone due to a defensive player, such as a kick (once the ball is kicked, the kicking team is considered 'giving up' the ball, and is therefore a defense), then the play results in a touchback to the 20 yard line (25 on kickoffs in the NCAA).
It would be considered a touchback and the ball would be placed at the 20 yard line.
It is 6 points if the ball is ran into the endzone, 7 if it is passed to a player in the endzone, 3 for a fieldgoal, 2 for a safety, and extra points can be 1, or 2, depending on their distance from the endzone.
Automatic First DownThere shall be no interference with a forward pass thrown from behind the line, is one rule about interference. Defensive pass interference is called when a defensive player interferes with a receiver's attempt to catch the ball. If the defender makes contact with the receiver, it is pass interference, unless the contact is incidental, or done in order to make a play on the ball. For example the defensive player can knock the ball down, even if he has to contact the receiver to do it. But he cannot push the receiver, trip him, grab his arm, pull his shirt, etc. Typically referees will call pass interference if the defensive player makes contact with the receiver but is not looking back at the ball.When defensive pass interference is called, the offense receives an automatic first down, and the ball is placed where the interference occurred. If the interference occurs in the end zone, the ball is placed on the one yard line. Pass interference cannot be challenged once called.
In college football, the penalty is 15 yards. In the NFL, the penalty is 10 yards.
Yes. Placement is always determined by where the ball is when the player goes down.
When commentators and football fans say "breaking the plane" they're talking about the endzone. The first and foremost rule in scoring a touchdown is that the football must break the plane or cross into the endzone some kind of way for anyone to even think about it being a touchdown. If a team runs the ball, it wouldn't matter if the player got his whole body into the endzone. If the ball didn't break the plane as he went in it is not a touchdown. If the ball is passed and is caught by a player who is falling forward out of the endzone and he doesn't allow the ball to break the plane it is not a touchdown.
A rushing touchdown is when the ball is carried into the endzone as opposed to being passed into the endzone.
It depends on whether or not he has the ball in his hands when he hits the ground of the endzone. If it is not in his possession, then it is a fumble and can be recovered by a defender. If it is in his hands and he touches the endzone, then it is a touchdown. If he was in possession of the ball when the ball crossed the goal line, it's a touchdown. As soon as the ball breaks the plane of the goal line, the ball is dead and the play is over. Anything that happens after that is irrelevant.
