According to Sports Science in an episode with Drew Brees his passes are all almost identical. The "spin" or Gyroscopic Torque is somewhere around 600 RPM when throwing at 52 MPH at 20 yards.
the spin of a football makes the football more aerodynamic, meaning that it can go farther than with out the spin by "cutting" through the air
A football is spiraled by the position your hand is place on the ball. Your fingers have to be placed on the laces of the ball and u must overhead throw while flicking your wrist.
A football oblique shape alllows it to spin through the air, the quarterback puts a spin on the ball with his fingers when he throws it. The best spirals are tightly spinning and take much experince to master
The answer has two parts - 1. Why do you want it to spin: It allows the bullet to be more accurate and travel further. The bullet spins for the same reason that football players spin a football when they throw it. 2. Why does it spin (How do you make it spin): Inside the barrel are grooves (rifling) that catch part of the lead of the bullet and spin it like bolt spins when you put it into a nut.
A football spirals based on the way it is thrown. It will be a perfect spiral if the football is thrown with the spin on the exact axis of the ball.Ê
there are various balls with soft covers, if you want spin it is how you hit the ball,that makes it spin and how much spin
when u spin around to much.

It makes the bullet spin when it is fired- much the same way a football spins in flight. The helps the bullet travel in a straight line, improving the accuracy of the gun.
