Yes but only in your house or if you have a yard with a fence around it.
No, the force of the gun results from the explosion of the gunpowder, propelling the bullet forward. The force of the bullet is the result of the acceleration it receives from the gun's explosion, which propels it in the opposite direction.
A pump action BB gun requires you to pump the forearm (The grip under the barrel) several times to store air in the air tube. This air propels the pellet when the trigger is pulled.
It is impossible for a weapon to "run out of gas." The expanding gas that propels the bullet out of the barrel is provided by the rapidly burning gun powder. Each new cartridge provides its own supply of this gas.
Yes, shooting a gun involves the conversion of mechanical energy into kinetic energy when the trigger is pulled, causing the firing pin to strike the primer in the bullet cartridge, igniting the propellant, which then propels the bullet out of the barrel.
When a gun is fired, the bullet propels forward with a certain momentum due to the force applied by the expanding gases in the gun barrel. According to the principle of momentum conservation, the gun must also experience an equal but opposite momentum in the backward direction. This backward momentum causes the sensation of "kick" felt by the shooter as the gun recoils.
On a paintball gun C02, or High pressure air is necessary. It is compressed air that, when the trigger is pulled and the marker fires, propels the paintball out of the barrel.
