What law will be used in this experiment?

[EelAnes]

The research question of this experiment stated "What is the effect of changing the air pressure (kPa) inside a soccer ball on the distance (m) that the ball will travel (when it first hits the ground) as measured by using the AG500 digital air pressure gauge (to 0.01 kPa) and a field measuring tape to 0.22m (roughly the diameter of a soccer ball)?"

The hypothesis of this experiment stated that as the air pressure inside the soccer ball increases, the average distance traveled when it first hits the ground will also increase.

The experiment will be done by using a range of 5 different air pressure—58.00kPa, 68.00kPa, 78.00kPa, 98.00kPa, and 108.00kPa—while using a Playmaker Soccer Ball Machine to launch the soccer ball and field tape measure to measure the distance it'll travel.

Well, what do YOU think ?

I believe that this experiment applies to the law of conservation of energy since energy does transform into from one to another. However, I think that the internal changes inside the soccer ball seem applies to other law. I believe that the law applied to the gas is the Kinetic theory of gases, particularly the average kinetic energy of the gas molecules.

I believe that this experiment applies to the law of conservation of energy since energy does transform into from one to another.

a). How does the pressure inside the ball translate to energy of the ball?
b). How does the energy of the ball translate to distance travelled?
c). Are the quantities referred to as "energy of the ball" the same in a) and b)?
d). How does a Playmaker Soccer Ball Machine work? What is held constant when balls of various inflation are propelled by it?
