It depends on the type of ammunition.
Gun can refer to a long gun or a hand gun. A rifle is very particular. It has to have grooved barrel which spin the bullet when it is going down the barrel. This spin action on the bullet makes it more accurate.
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.
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
That would depend on the mass of the bullet, the bullet's velocity when it left the barrel of the gun, and from how high up the bullet was fired from.
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.
bullet+metal=gun
That is where the bullet comes out of the gun.
