A perfectly thrown football is called a Spiral.
When a football is thrown, it possesses potential energy due to its stored energy from being held above the ground. As it is thrown and moves through the air, this potential energy is converted into kinetic energy, which is the energy of motion. The football's total energy is the sum of its potential and kinetic energy.
Once the football is in air, assumed quiet, it is acted upon by at least two forces -- gravity and air friction/drag.
I once threw a football over 50 yards in a game, which was the most impressive thing I've ever thrown into the air.

The ball was thrown high into the air.
The force of friction is not acting upon a ball that is thrown in the air. Friction is a force that opposes motion, but when a ball is thrown in the air, there is no surface contact for friction to act upon.
A football with no air is heavier than a football with full air because the air adds buoyancy and makes it lighter.
It should make a good spiral to the receiver and the ball goes up in the air and back down so the receiver can try to catch the ball.
a spiraled ball goes farther becuase its spiraled motion flows through the air and a wobbly pass does not.
air is in the football
An object that is thrown or shot into the air is commonly referred to as a projectile. This term is often used in physics to describe an object in motion through the air due to an initial force.
