It does but not so noticibely, you can throw a football about 1 ounce less than one and barely notice
A kicking football is essentially a brand new football that is fresh out of the package. A throwing football is a "broken in" ball that is more used and easier to handle.
Im pretty sure they were throwing before they were running throwing has always been a technique in football but both ways of the game have new plays and new ways of throwing and running the balll.
All positions in football are important, so I can't say.
I'm QB of my high school's flag football team and I can throw 30-40 yards
Throwing a football is considered mechanical energy because it is the sum of potential energy and kinetic energy. Mechanical energy is when something is in motion.
