Wilkes Booth John.
The bullet fired from a gun has greater horizontal acceleration. For vertical acceleration, they are both the same.
I used gelatin or a large water tank.
When a bullet is fired into the sky, it will eventually stop becasue it has run out of energy and fall back to the ground.
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.
Yes, a bullet can potentially knock someone over with the force of impact. However, there are many variables that can influence the effect of a bullet, such as the caliber of the bullet, the distance it is fired from, and where it strikes the body.
No. The bullet will actually travel much slower due to wind resistance.
Yes.
Yes
hash marks or lines running parallel with the casing, caused by the inside of the barrel of the gun as the bullet travels out when fired
When a bullet is fired, it can reach temperatures as high as 2,500 degrees Fahrenheit due to the combustion of gunpowder and friction during the firing process.
When a bullet is fired from a rifled firearm, the rifling leaves marks on the bullet. Those marks are unique to that gun, and no other gun makes exactly the same marks. If a bullet (or fired cartridge casing) is recovered from a crime scene, and we suspect that YOUR gun was used to commit this crime, then a sample bullet is fired from your gun, and compared to the crime scene bullet. A comparison microscope is used to compare the bullets, or marks made on the fired cartridge case by the extractor and firing pin.
A bullet fired from a gun has more momentum than a train at rest because momentum is the product of an object's mass and velocity. The bullet, despite being smaller in mass compared to the train, can have a significantly higher velocity, resulting in a greater momentum.
