World Cup Science
Rensselaer Polytechnic Institute scientists have discovered how a kicker’s body can reveal where he’s aiming.
In a penalty shot, the ball can touch net in about half a second - faster than a keeper can go from the goal’s center to either post ... meaning the goalkeeper must move before the kicker’s foot meets the ball AND correctly guess the direction.
The angle of the kicker’s hips and the way he plants his supporting foot are the most telling factors.
