In fluid dynamics, drag -- or air resistance -- is a force opposite to the direction of the ball. It can be influenced by the roughness and seams of the ball. In fact, these seams are key to make the trajectory of a ball predictable. A smooth ball would be "terrible," said Hosoi, who founded the MIT Sports Lab.
