What is the total momentum of the bullet and the gun on firing?
The total momentum of the bullet and the gun before firing would be zero because velocities of both of them will be zero.
What is the net momentum of gun and bullet system before firing?
The net momentum of the system is zero in accordance with the law of conservation of momentum. It states that the momentum of a system is conserved during a process. So, as the net momentum of bullet and gun before firing is zero ten the net momentum of bullet and gun after firing will be zero as well.
When the momentum of the bullet and the gun is equal then why it is that bullet kills the target whether the gun does not kill the gunman by recoiling?
Momentum is transferred from the first object to the second object. In this case, if a gun exerts a force on a bullet when firing it forward then the bullet will exert an equal force in the opposite direction on the gun causing it to move backwards or recoil.
Why does a gun recoil backwards when fired?
When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is force is called as the action force. The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.
Why does a gun recoils when you pull the trigger?
In technical terms, the recoil is a result of conservation of momentum, as according to Newton’s third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced …
Does a bullet leaves the barrel before recoil?
Recoil occurs after the bullet exits the barrel. REcoil also occurs before the bullet exits the barrel.
Why is the acceleration of the gun much less than the acceleration of the bullet when the gun is fired?
Answer. ▶️ Because, the mass of the gun is more and the mass of the bullet is less , exert pressure to move or accelerate . As we know that every object has an equal and opposite reaction , so if the bullet moves forward the gun will move backward a bit .
What is the most important firearm safety rule?
1. Always Keep the Muzzle Pointed in a Safe Direction. This is the most basic safety rule. If everyone handled a firearm so carefully that the muzzle never pointed at something they didn’t intend to shoot, there would be virtually no firearms accidents.
What causes a loud sound when a gun is fired?
Muzzle Blast A conventional firearm uses a confined explosive charge to propel the bullet out of the gun barrel. The hot, rapidly expanding gases cause an acoustic blast to emerge from the barrel. The acoustic disturbance lasts 3-5 milliseconds and propagates through the air at the speed of sound (c).
