The Physics of a Spiral: Throwing and Catching a Football

~60 min · 15 stations

The Physics of a Spiral: Throwing and Catching a Football is a self-paced learning path in Physics & Quantum Mechanics, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to identify basic forces acting upon a thrown football; explain why the prolate spheroid shape matters; define angular momentum within rotating systems.

Conductor

The Conductor

All aboard for a flight through the air. We are mapping the invisible forces that make a football spiral true.
