Question

Why can a small moves such a bullet killed the person when fired from the gun

Answer 1

Bullet's mass is about 20 grams to 50 g. It is released from the gun at a very high speed like 200 kmph to 400 kmph.

So the momentum is high. When a bullet hits a human being the force, pressure and impact are very high as its surface area is small.

That's why a bullet is fatal.

☞Because the velocity of bullet fired from the gun is very high.So, the momentum of the bullet fired from the gun is much higher than the bullet thrown with the hand. hence, it may kill a person when fired from a gun.
