The Physics of a Bending Free Kick

~60 min · 15 stations

The Physics of a Bending Free Kick 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 fundamental forces acting upon a moving ball in flight; describe how air molecules behave when moving around curved surfaces; apply Newton's laws to explain ball trajectory deviations.
