When any object goes through the air, a thin cushion of air wraps around it that stays relatively still. This boundary layer is why you get dust trapped on your ceiling fan. At slower speeds, the air around a soccer ball moves smoothly over the surface and separates off the sides of the ball at its widest points. Imagine a ball moving from right to left across a clock, Goff explains, so traveling from the 3 to the 9. With laminar flow, the air flows over the surface and then flows off at the 12 and 6, which creates more drag in the air. Drag slows the ball down faster. At higher speeds, the air moves turbulently across the ball’s surface and peels off at the 2 and 4. The wind effectively wraps around the back. This turbulent flow has less drag, which means the ball keeps moving at high speed for longer.
In 2010, the infamous Jabulani balls for the World Cup in South Africa transitioned from turbulent to laminar flow between 50 and 45 miles per hour, right at the speed for corner and free kicks. The transition between these different types of flow causes even more drag on the ball, which caused the Jabulani to wobble in the air and drop in ways that players weren’t expecting.

Well, panels are not any different component. Panels are the segments or octagon quilt that are seen outside the balls. Of course, nowadays you will find some other shapes besides octagon. FIFA official balls usually contain 32 panels. But nowadays you will also find 26, 18, 14, 8 or even 6 panels with different shapes and designs from those of conventional balls.
Our main intention of finding the official match balls was to help you find a solution which is good in quality, and you can use it for league plays. The process was tough we must say. Not all the replica balls have good quality. That is why we were very choosy in the process. We filtered the balls not only based on our experience but also based on the experience of other users.
This can be used as a great option for goalkeeper training as well. Why? Look, you can hardly see the lines on this ball, hence you won’t be able to guess the direction by only seeing the spin of the ball. That means as a goalkeeper you will have to give full concentration to detect the direction of the sliding balls. This is obviously helpful if you are a goalkeeper, and looking for a sliding challenge.
It depends on its intended use. Soccer ball casings are made from three kinds of synthetic materials. Polyvinyl carbonate (PVC) which is what most less expensive training balls are made from, Polyurethane (PU) which is the preferred ball for soccer tournaments, and a combination of the two. There are also foam and rubber training soccer balls for kids. Some kids' soccer balls are made of 100 percent thermoplastic polyurethane (TPU), which is a kind of foamy casing material so the ball is very soft. There are greater and lesser grades of each kind of material. PU-covered balls are generally softer, livelier, and have a better feel to them, and are what most people seek when looking for a optimal performing soccer ball.
At the World Cup level, these tiny changes in a ball’s aerodynamics can legitimately impact a team’s performance, so the intense scrutiny of the World Cup ball is perhaps to be expected. “You could argue that it’s the most important piece of equipment in the most popular sport in the world,” says John Eric Goff, Professor of Physics at University of Lynchburg.
