Here's what ChatGPT had to say about throwing a spiral vs a wobble:
"A football that is thrown with a tight spiral will generally travel more accurately and efficiently through the air compared to a football that wobbles. The primary reason for this is the phenomenon known as the Magnus effect.
When a football is thrown with a tight spiral, it spins rapidly around its longitudinal axis. This rapid spin creates a stable and predictable airflow around the ball. The Magnus effect occurs because of this spin, where the pressure difference between the front and back of the ball creates a lifting force perpendicular to the direction of motion. This effect helps the football maintain a stable trajectory and minimizes air resistance, allowing it to travel farther and more accurately.
In contrast, when a football wobbles or does not have a tight spiral, the airflow around the ball is disrupted and irregular. This can lead to unpredictable movement, reduced accuracy, and increased air resistance. As a result, a football thrown with a tight spiral is generally more effective in terms of speed, distance, and accuracy compared to one that wobbles.
So, while the tight spiral itself doesn't make the football travel faster in terms of absolute speed, it contributes to a more efficient and accurate flight, which can result in better overall performance in terms of distance and accuracy when throwing the football."
So the bottom line is that accuracy is improved (and probably velocity due to reduced air turbulence) if you throw a tight spiral.
