The pressure in the atmosphere will also affect how far the ball when kicked. The lower the pressure then the less friction there is for the ball to travel. -Air pressure determines the ball’s level of stiffness. Higher air pressure creates more energy, and allows the ball to keep its shape when it is kicked.
How does air pressure affect a football?
The more pressure that is held within the ball, then the higher that the ball will bounce when compared to a deflated ball. The air pressure within a football can play a much greater role if the ball is not inflated to the recommended levels.
Does air pressure affect the distance a football travels?
This soccer science fair project serves to acquaint students with basic information on how the amount of air in a soccer ball can affect the distance it travels when kicked with a consistent force. The greater the air pressure in the ball, the farther it will travel when a force is applied.
What is the best air pressure for a football?
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.
What is the air pressure of a football?
The NFL requires that all game footballs be inflated to a pressure between 12.5 and 13.5 pounds per square inch (psi), and that they weigh 14 to 15 ounces (397 to 425 grams), ESPN reported. The footballs in the playoff game were underinflated by 2 psi.
Why do balls lose air?
They deflate over time because the material they’re made out of isn’t completely air-tight and some leaks out over time. The valves needed to inflate the ball also leak some air over time.
How is deflating a football cheating?
In the end, the reason for deflating a football owes more to physiology than physics. A slightly deflated ball is a bit softer, making it easier to grip the ball to throw it and reducing the bounce when it hits the hands of a receiver, making it easier to catch.
Does the amount of air in a soccer ball affect how far it goes experiment?
My science fair topic is ‘does the air pressure inside a soccer ball affect the distance that the ball will travel in the air’ I completed my experiment using a catapult to fire the ball. The results showed no difference in the distance travelled when using different pressures between 1-16 pounds.
Is it easier to kick a deflated soccer ball?
With the fully deflated ball there will be bigger lumps in the ball causing the ball to slow down when it is rolling and it will be lighter which will make the ball harder to kick. Procedure. (Do the same for the semi inflated and fully deflated footballs.)
How do we measure air pressure?
Cell Phone Barometers
Whether or not you have a barometer in your home, office, boat, or plane, chances are your iPhone, Android, or another smartphone has a built-in digital barometer! Digital barometers work like an aneroid, except the mechanical parts are replaced with a simple pressure-sensing transducer.
Which air is filled in football?
Also, helium is much lighter than air, so the coach wants to know if they can kick the ball farther if it is filled with helium.
Can helium filled footballs be kicked farther than air filled balls?
|Air Mean||Helium Mean|
How much should you pump up a football?
Manufacturers will always give you the recommended pressure for the soccer balls that they produce. This is the ideal amount of air pressure inside the soccer ball, and it will be expressed in psi, pounds, or bar. Normally, you will want between six and eight pounds of pressure.
What does FIFA stand for?
FIFA — Soccer’s World Governing Body
Founded in 1904 to provide unity among national soccer associations, the Federation Internationale de Football Association (FIFA) boasts 209 members, rivaling that of the United Nations, and is arguably the most prestigious sports organization in the world.
How do you remove air from a football?
Insert the moistened end of the paper clip or pen into the valve of your soccer ball. Like the pump and needle method, use your writing hand to hold the paper clip and your other hand to hold the ball near the valve. Apply gentle pressure until you hit the pipeline of the bladder and feel air coming out of the ball.
What is the weight of football?
A regulation football is 28–30 cm (11–12 in) long and 58–62 cm (23–24 in) in circumference at its widest point. It weighs 410–460 g (14–16 oz) and is inflated to 65.7–68.8 kPa (9.5–10.0 psi).
What pressure is a premier league ball?
made of suitable material. of a circumference of between 68 cm (27 ins) and 70 cm (28 ins) between 410 g (14 oz) and 450 g (16 oz) in weight at the start of the match. of a pressure equal to 0.6 – 1.1 atmosphere (600 – 1,100g/cm2) at sea level (8.5 lbs/sq in – 15.6 lbs/sq in)
