Roberto Carlos Kick Speed

1.) Incredible speed. The first step in a kick like this is to get the ball moving as quickly as possible, which is some of the most straightforward physics there is: simple momentum transfer. A regulation soccer ball weighs about 14-16 ounces (410-450 grams), while a human leg is much heavier. However fast a human can swing their foot at the moment of impact with the ball, that ball can rocket off at up to twice that speed, a consequence of a nearly perfect elastic collision between a heavy mass (the leg) and a light one (the ball).

The faster a soccer ball moves, the more of a turbulent wake it leaves behind it. Over time, air resistance will slow down a soccer ball no matter how quickly it was kicked, and less of the flow becomes turbulent while more of the flow becomes laminar as its speed drops.

In 1997, while he was undergoing a match against France, Roberto Carlos made a commotion to the world. He scored a spectacular goal that cannot be explained logically. When he got the chance for a free kick, he successfully shot the ball towards the French goal through a truly irrational ball move. The kick speed reached 169km / hour.

His crossing ability is ideal for an overlapping full-back and he is always capable of his free-kick goal in the 1997 Le Tournai given his long free kick stance, his shot power, swerve and FK abilities. Roberto Carlos also has impressive speed despite his growing age.

The researchers used a combination of wind-tunnel experiments, high-speed video camera analysis, trajectory simulations, and computer modeling techniques to explain what happens when a soccer ball bends during a free kick. Takeshi Asai of Yamagata University's Sports Science Laboratory used MSC.Patran a product of MSC.Software of Los Angeles, to model the stress and deformation of the foot and ball as the player strikes the ball. This simulation was combined with computational fluid dynamics research done by...
