When the cartridge fires, it ignites gunpowder inside the cartridge case. Burning of the powder quickly produces a large volume of high pressure gas. This expanding gas pushes in all directions, but the bullet is the only part that can move. The expanding gas pushes the bullet through the barrel, and out of the gun.
The bullet jammed in the gun's chamber. Come into my chamber and sit down.
Theoretically, yes. It would most likely destroy or damage the second gun beyond repair.
The gun weighs MUCH more than the bullet.
The total momentum of the bullet and the gun before firing is zero, as the gun and the bullet are at rest. Momentum is the product of mass and velocity, and since both the gun and the bullet are not moving, their momentum is zero.
When a bullet is fired from a gun, the gun exerts a force on the bullet, propelling it forward. Simultaneously, an equal and opposite force is exerted by the bullet on the gun, causing recoil. This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
Affix the gun to a target. Load the bullet into a cartridge. Load the cartridge into a second gun. Aim carefully, squeeze the trigger. If you have done everything right, you will have shot the gun with a bullet.
It's the recoil from the force of the bullet being fired. The gun powder pushes the bullet forward and also equally pushes the gun back into your hand.
Chastain - Bullet From A Gun
I assume what you are asking is "if you shoot a gun straight up in the air will the bullet come down at the point where it was shot from". The answer to that question is NO, the rotation of the earth will move the point of impact.
A bullet leaves a gun barrel because it is forced out by the pressure of burning gasses.
The bullet is moving forward, and is spinning. As the bullet moves away from the gun, it falls towards the earth from gravity.
