퐹 = 1/2휌퐴휐2퐶 2 2 - l i n f i e l d m a g a z i n e Winter 2016 English (bend it like Beckham) soccer player David Beckham made famous the skill of scoring from free kicks by curling the ball past a wall of defenders. Just how do athletes “bend it like Beckham”? Garry Killgore, department chair and professor of human performance, explains the science behind the sport, referencing the “Magnus Effect” physics equation (see above). The soccer player is able to “Bend it like Beckham” due to a pressure differential that is created by the player kicking the ball with the inside of the foot while putting spin on it, i.e. the “Magnus Effect.” A pocket of high pressure is created on the side of the ball that is being kicked and low pressure on the opposite side. The ball will subsequently “bend,” or deviate from the original flight path, toward the low pressure area and follow a path that may allow the soccer player to score a goal from the corner of the field. Wildcat soccer midfielder Ivan Colin ’16 kicks the ball with teammate Brandon Brooks ’16 in the background.
