The pressure inside a football is caused by the air particles inside the ball being compressed by the addition of increasing amounts of air. The standard PSI of a professional football is 13 psi (Pounds per square inch).
Yes, the inside and the outside of the ball.
The ball is placed inside the corner arc (on the line is considered inside). The ball must be kicked and must move.
You tackle the ball, not a player.
he found the ball and also found love.
Gas is made up of lots of particles that are all flying about bouncing of anything the touch. The more pressure there is the moreparticles there. So at normal pressure outside the ball there is a normal amount of particles hitting of the outside of the ball. On the inside of the ball the pressure is higher so there are lots of particles hitting of the hinside of the ball effectively pushing it out. Hope this makes sense :)
You call it football because you play with ball and kick the ball
A soccer ball is round, a football is shaped like a lemon. A soccer ball is smooth, a football has some grip. A soccer ball is a lot bigger than a football.

The same way as outdoors. But inside the ball has a bit more bounce.
