After a team scores a touchdown in football they can earn additional points on an untimed down called the try.
After a touchdown is scored, teams can earn one or two additional points. This is called the PAT or try.
Football Extra Points
The extra point requires the team to kick the ball into the opposing team's goal post starting at the 15 yard line.
Football 2 Point Conversion
The 2 point conversion requires the team to carry or catch the ball in the opposing team's end zone. Teams start on the opponent's 2nd yard line.
REMEMBER: No one calls it a try in football. This term is only used in the rulebook. Everyone calls the try the extra point or the 2 point conversion.
