How is a bullet fired from a gun?

Answer 1

A cartridge is that cylindrical container that has an explosive inside, a projectile (bullet) on one end, and a cap (like a match) on the other end. It is loaded in the gun.

When the trigger of the gun is pulled it causes a firing pin to strike the cap on the cartridge. The cap ignites the explosive in the cartridge causing a very rapid expansion of the combustion gases inside the cartridge. The gases push on the walls of the cartridge and the bullet. The gun supports the walls of the cartridge and prevents the cartridge from deforming or tearing. But something has to give to release all that pressure. The bullet is what gives. The expanding gases push it through the barrel of the gun. If the gun is properly designed the bullet leaves the gun before the friction of the barrel starts to slow it down.

If the shooter has aimed the gun properly the bullet hits the target.

Answer 2

When the bullet is shot in the air, it does not go into outer space. Once it gets to a certain point gravity pulls it down and eventually the bullet will go through someones head and kill them. Especially on 4th of July it is even illegal to do that.

Answer 3

Every moving body has kinetic energy. Since the moving bullet had kinetic energy it transferred that energy into the stable tissue. Now the target which actually was at rest moved because of getting energy and because of law of inertia got pierced. I hope this would help you get answer to your question.

Answer 4

They go in the direction of the barrel until air resistance slows them down and gravity has pulled them to the ground.

Answer 5

... as soon as it leaves the muzzle of the rifle.
