Soccer balls lose air pressure over time firstly because the outer material construction is not air-tight, meaning that over a certain duration of time the air will gradually seep out.

Does the size of a soccer ball affect how far it goes?

Objects on the Ground

Similar to balls in flight, surface friction impedes the movement of balls with low mass-density, such as soccer balls, more than it does those with high mass-density, such as bowling balls. In other words, given equal size in terms of diameter, the ball with the greater mass will roll farther.

How does air pressure affect a soccer ball when kicked?

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.
