Recoil from the explosion of the charge.
It is because of newton's third law ...... According to this law , every action has an equal and opposite reaction . Therefore , when a gun is shot ( here the action force ) , the bullet is fired out (released) from the gun with a high force . As a result the gun has to produce equal and opposite reaction . As a result , the gun jerks back ....... In order to reduce the " recoil " of the gun ,the mass of the gun is increased . That's why guns are usually heavy weighted .
It's Newton's law that every action has an equal and opposite reaction. The bullet goes away from the person firing. It has a very small mass but a very high speed. The opposite reaction is the gun moving backwards, but since its mass is much higher than the bullet, its speed in much lower.
Firing Pin
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.
You compare the rifling marks on the bullet to the rifling in the barrel. You can also compare the firing pin mark on the primer to the firing pin on the gun.
The term "magic bullet" refers to the bullet found on the gurney that JFK was on when he died. It was next to his head. It just seemed to appear and for the conspiracy types it proves there was another gunman other than Oswald.
Most of the time there is a firing pin, which hits the back of a bullet when the trigger is pulled. The firing pin hits the back of the bullet and ignites the gunpowder inside of the bullet. The bullet then becomes a small unguided rocket and hits something in the direction the gun was aimed at.
Firing pin is what strikes the back end of bullet igniting propellant
Exactly the same as whatever it was before firing. If the loaded gun was not movingbefore the trigger was pulled, then the total momentum of the gun and bullet afterfiring add up to zero.
A bullet from a handgun can travel, on average, about a mile.
