How forceful a player throws the ball: here's the equation:(Force = mass of football x acceleration due to gravity). The football flies because a spin is put on it. This spiral action makes it more aerodynamic and it will travel farther and straighter.
Putting that perfect spin on a football is all about the distance, its the precision it creates. Also the spinning makes the ball fly easier in between air particles, which results in the football being able to fly farther with less friction.
