When a football is thrown most expect it to spiral through the air to its target as opposed to flipping over itself and missing its target completely or possibly getting picked off. Most just have to find their rhythm and what works best for them.
But there are some who believe that if the football makes its target without any chance of it being intercepted then it could be thrown backwards for all they care.
Follow through with your throwing motion.
kicking a football, throwing a stone, ballistic missile, satelites...etc
Shoulder muscles are used when throwing a football. They give the arm support and are needed during the actual throw. In the throwing motion the triceps and biceps are used. The core muscles are used to help the thrower stay balanced.
First of all it's kinetic energy. Kinetic energy is when something is in motion. The football would be in motion when it is in the air. It would also have potential energy. Potential energy is when an item is about to have kinetic energy, or when your about to throw the ball. -I'm 12 years old. If whoever posted this question is older than me, that's weird.

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.

Yes it strengthens his arm and he will have to adjust his throwing motion.
When throwing a football, you primarily use the motion of your arm and your wrist. Your arm generates the power and direction of the throw, while your wrist provides the additional control and spin on the ball.
A pro football because the quarterback is used to throwing the pro football and not a Nerf football.
