Physics of the Magnus Effect in Soccer

The video explores Roberto Carlos' legendary 35-meter free kick in 1997, highlighting the physics behind it, particularly the Magnus effect. This effect, which causes a spinning ball to curve due to pressure differences, is explained in detail. The video also discusses the challenges of executing such a kick with precision and its applications in other sports. Finally, it addresses the theoretical limits of the Magnus effect, debunking the possibility of a ball boomeranging back to the kicker.
