Why the impact of bullet is so strong when fired from the gun?

According to law of conservation of momentum mass of bullet is much smaller than the gun therefore the recoil is much… reater than the velocity of gun. Therefore the impact of bullet is very strong.

Why is a gun far heavier than a bullet?

Switching to a heavier bullet increases recoil, causing more muzzle flip and raising the point of impact, but the heavier bullet usually exits the muzzle at a lower velocity, increasing bullet drop, which lowers the point of impact in relation to the bore axis.

Does a bullet have inertia?

Because inertia is a body’s to remain in a constant state. So the inertia of a bullet has no bearing on the force it can exert. That force is a function of mass and velocity or more correctly acceleration. Inertia has nothing to do with it in the case of a gun and bullet.

Why the recoil velocity of gun is much smaller than the velocity of bullet?

Answer: It is due to the law of conservation of momentum. The total momentum of the gun and bullet after firing is equal to the total momentum of the gun and bullet before firing. Since, the mass of gun is much larger so the velocity of recoil is much smaller as compare to the velocity of bullet.

Why is the speed of a rifle recoil small?

From the conservation of momentum, the momentum of the rifle is equal to the momentum of the bullet. Momentum is given as mv. Therefore, the speed of the rifle’s recoil is small because it has much more mass than the bullet. This helps in keeping the momenta of the rifle and the bullet equal.

How many joules are in a bullet?

Depending on the caliber, weight and muzzle velocity, a bullet can have anywhere between 105 and 20,000 joules…

What is the total momentum of the bullet and gun before firing a bullet of mass m and velocity v?

zero
The total momentum of the bullet and the gun before the firing is zero because both are at rest.

What is the momentum of bullet?

about 3.2 kgm/s
Public Domain Image, source: Christopher S. Baird. One of the most widely used handguns, the Beretta M9, has a typical bullet mass of 0.008 kilograms and a typical muzzle velocity of 400 meters per second. Multiply these two numbers together and you get a bullet momentum of about 3.2 kgm/s.
