Usually, unskilled adult players can hit a soccer ball 50 yards, from the goal square past the central line, and trained goalkeepers such as Edwin van der Sar can make the ball cover three-quarters of the distance of the pitch. A distance kick needs the ball tapped up to be acceptably solid, which the referee analyses before the game by pressing his palms on each side of the ball just before beginning. Sports scientists and engineers — as well as science exhibition members — have given attention to studying how the air pressure changes the distance a soccer ball moves when kicked.
The international ruling body of the soccer FIFA requires grown-up athletes to use a soccer ball within 26 and 27 inches around, within 14 and 16 oz. in mass, and pressurized to 8 to 15 pounds per square inch. A ball pressure scale with a needle that moves in the soccer ball lid and a dial covering up to 20 psi, can indicate exactly if the ball is between the mandated scale. A standard exercise ball may be marked to be filled within the level of 6 to 8 psi; in this situation, the referee will determine by holding the ball whether to stay as per the manufacturer’s instruction or raise the pressure to the minimum of 8.5 psi.
The greater the air pressure in the soccer ball, the faraway it will move when it is kicked, addresses soccer ball enthusiast and engineer Bruce Rigsby. Your kick gives more power to a solid ball, as compared to a springy one, as less of the power is spent to deformation of the ball’s exterior. So, the amount of air pressure in the soccer ball affects how far its go. The same idea fits with other inflated games stuff: A basketball jumps lower if not filled accurately, and a bike tire contacts more of the road if underinflated, decreasing performance.
Atmospheric air pressure also influences a way the ball moves when kicked, Rigsby says. Lower the pressure, the less resistance. This is the same principle that drives to so many home points being run at the Colorado Rockies’ home, Coors Field, a higher sea level, as a baseball also moves with less friction at altitude.
The laws of how air pressure affects a soccer ball travel make the point fit for experimentation as part of a science fair project. Science instructor and author Muriel Gerhard suggests filling a soccer ball at low, medium and high levels and hitting the ball at the same power inside a gym. Have an assistant mark the point where the ball arrives each time. Do three experiments at each pressure, write the results and equalize them. Form a line graph of the driven data, and report on your first hypothesis and how the results turned them out.
