You're not serious, are you? What the heck do you think, it fills with air, numbnuts.
it infates
The inside of the ball becomes filled with the air you pump in, thus inflating the ball and turning it from a flat ball to a round one.
Blow inside the ball through the hole!
Pumping pushes more air molecules into the ball. That makes more molecules moving around inside of the ball and more molecules colliding with the inside of the ball. All of those collisions (trillions and trillions) push the inside of the ball out. When the temperature is increased, the molecules move faster. Faster molecules collide with the inside walls more frequently, which also increases the pressure. You can test this by pumping up a ball then putting it into the freezer and see what happens to the pressure.
Its the friction of the stopper inside rubbing against the tube.
You add air to it by using a pump. Or if it has a hole in it, stitch u the hole or by a new ball.
As air fills the basketball, the pressure expands outward to make the outside of the ball feel harder. The valve on the outside of the ball allows the pump to put air in prevents air from escaping.
If you are talking about a water pump then the kick-back is what happens when the pump is working and the water is flowing inside the pipe then when the pump stops the water flow suddenly stops as well and the column of water inside the pipe falls back because of gravity, if this is not prevented then the impulsor inside the pump, the seal or both can get damaged.

you are going to get caught by the polise
Use a pump to pump it up.
