Moment of Science: The Science of Spin

Episode 109: What does soccer, baseball, tennis, and countless other sports featured in the Olympics have in common? They all rely on the Magnus Force to bend it like Beckham, throw a mean fastball, or put massive topspin on a return. This aerodynamic force kicks in when an object traveling through the air starts spinning- creating areas of high and low pressure on different sides of the ball. This in turn, creates a force perpendicular to the object’s motion, curving the trajectory up, down, or even sideways! This force only gets bigger as the object spins faster, so skilled players must master techniques that use spin to outwit and outplay their opponent.
