False Start
: When a football player on the offense moves just prior to the snap. This is a five yard penalty.
: When a player grabs a football player without the ball with the hands or hooks him or tackles him.
: To protect the football players, it is illegal to grab another player's facemask.
Intentional Grounding
: When the passer throws a pass nowhere near an eligible receiver strictly to avoid being sacked.
: If a player from the offense or defense is on the wrong side of the line of scrimmage at the time of the snap. A defensive player can cross the line of scrimmage as long as they get back before the snap, but if they touch an offensive player they can be called for encroachment.
Roughing the Passer or Kicker
: To protect kickers and quarterbacks, who are very vulnerable when they are passing or kicking the ball, players are not allowed to run into them after the ball has been thrown or kicked.
