Does an NFL kicker use a special football?

Answer 1

yea, the balls used for special teams have the letter k written on them.

The K Ball came to being after many NFL Kickers were having super-natural field goal percentages and making over 90% of their kicks. The NFL and Commissioner deemed it necessary to make it more challenging for kickers, thus the "K Ball" was born. The K Ball, simply stands for 'kickers ball' and it is handled by a special field crew who ensure the ball is inflated to 13 PSI (Pounds per Square Inch) which is very compressed and hard. So in cold weather conditions, you can expect the field goal to travel about 5-7 yards less than the normal distance an NFL kicker can kick.
