Magnus effect

Show Summary Details

Quick Reference

The deviation in the trajectory of a spinning projectile caused by the Magnus force. The deviation is toward the direction of the spin and results from pressure differentials in the spinning projectile. The Magnus effect can be observed when a golfer hooks or slices a shot; when a footballer executes a ‘banana shot'; and when a baseball pitcher throws a curve ball. The Magnus effect is greatest when the axis of spin is perpendicular to the direction of relative fluid velocity.
