Your kick transfers more energy to a stiff ball, compared to a spongy one, as less of the energy is lost to deformation of the ball’s surface . Thus, the extent of air pressure in the ball affects how far it sails off your foot.
What is the air pressure in football?
Game footballs are required to be inflated to at least 12.5 PSI according to collegiate and professional rules.
Does air pressure affect the distance a football travels?
The greater the air pressure in the ball, the farther it will travel when a force is applied . ... The student will learn about the relationship between air pressure and friction: the lower the friction, the farther the ball will go.
How does the amount of air in a football affect how far you can kick it?
The greater the air pressure in the ball , the farther it will travel when a force is applied.
How does air resistance affect a soccer ball?
The effect of air resistance on the flight of a ball becomes more pronounced at higher launch velocities .
What is the best air pressure for a soccer ball experiment?
For example: A soccer ball has a recommended pressure of 7.9 Lbs. (PSI) labeled on it. To convert Pounds Per Square Inch (PSI) into BAR, multiply 7.9 times .
What is the best air pressure for a soccer ball?
In its section on rules about “The Ball,” it states that they must be spherical and inflated to a pressure between 8.5 psi and 15.6 psi . When a soccer ball is inflated with less than 8.5 psi, it is more difficult to kick and send down the field and is considered too flat.
How does air stay in a football?
When a soccer ball air valve is closed, the hole is perpendicular to the passageway, which doesn’t allow air to enter or exit the ball. Whatever air is in the ball will stay inside . When the valve is open, the hole runs in the same direction as the passageway. This allows you to inflate the ball with air.
How does air pressure helps to inflate a football?
Explanation: Use the air pump until the gauge on the pump shows the necessary BAR or P.S.I. For example, if your football should be at 0.5 – 0.7 BAR (7.2 – 10.1 P.S.I.), keep the pump on until the gauge is between those numbers. ... Do not over-inflate the ball by going over the recommended BAR or P.S.I....
Does temperature affect football?
Cold weather affects , first and foremost, the football itself. The air pressure of a football is reduced by 20% in cold weather. Many footballs are inflated indoors, then brought into the cold, so the pressure in those footballs may drop during the game.
Where should I kick a soccer ball?
When striking with the top of the foot [laces] you want the ball to go straight. Point your hips, plant foot and shoulders where you want the ball to go. Also you need to have both knees bent a little. The more you have your plant leg bent, the more you can get under the ball to it up high.
Are soccer balls aerodynamic?
In addition, theRe crit values of the soccer balls were lower than those of smooth spheres, ranging from ∼ 3.5 × 105 to 4.0 × 105, due to the effects of their panels. This indicated that the aerodynamic properties of a soccer ball were intermediate between those of a smooth ball and a golf ball.

What pressure is a premier league ball?
Regulation size and weight for a soccer ball is a circumference of 68–70 cm (27–28 in) and a weight of between 410–450 g (14–16 oz). The ball should be inflated to a pressure of 0.6 and 1.1 bars (8.7 and 16.0 psi) at sea level .
Why do soccer balls lose air?
Soccer balls lose air pressure over time . Sometimes over a few days (soccer balls that use butyl bladders keep air pressure longer than balls that use latex bladders). ... Before you first inflate a soccer ball, place a couple drops of silicone oil or silicone lubricant spray or glycerin oil into the valve.
Can you kick a deflated football farther?
By kicking it at a lower angle you can actually get the ball to travel farther . ... The change in air density might give a kick an extra 4 or 5 yards of distance. So, it might matter a little bit.
