I don't know if this answer will satisfy you, but there is not much difference. Higher velocity is higher speed. But 1100 feet per second (appx) is the speed of sound, and guns that have a "subsonic" bullet are much quieter than guns whose bullets break the sound barrier at just a slightly higher velocity.
Answer:
To truly discuss firearm velocity issues would require the writing of a book, but it suffices to say that one of the usual differences is chamber pressures and barrel life. The super high velocity calibers such as the 220 Swift generate so much heat that the rifling can be worn from the barrel in as little as 3000 rounds, whereas a lower velocity round such as a 30.06 barrel has a longer barrel life.
The next obvious difference is trajectory. As it takes a certain velocity to break from the earth's gravity, the same holds true with bullets. The faster it is traveling to longer it takes for gravity to lower it from its aimed point.
Last, but not least. Hollow point bullets require higher velocities to properly expand and release more energy into it's intended target. This becomes a real issue when fired from a handgun.
muzzle velocity is the velocity of bullet and recoil velocity is the velocity of gun.
Both are tracked vehicles. An assault gun is usually a turret less vehicle, mounting a (usually) high velocity gun used in a direct fire mode, used for attacking an enemy position. A self propelled gun is usually an artillery piece (indirect fire), and is tracked to allow self propulsion.
Momentum = mass x velocity A bullet has a high momentum because its velocity is really high.
Depends on the area that you're in and the velocity of the gun itself
The sherman tank was constantly upgraded throughout it's service history. With several variants in service simultaneously. During WW2 Originally intended for infantry support it used a medium (relative to it's time) velocity 75mm. A low velocity 105mm howitzer. A high velocity 76mm anti tank gun. A high pressure flamethrower. A high velocity 17 pounder anti tank gun. After WW2 Israel upgraded shermans with high velocity 75mm and high velocity 105mm guns.
Mainly in the stock
bronze and gun metal
Summer gas pressure is higher, and so are velocities. The gun will shoot a bit high.
Stock dimensions and sights
it depends on the velocity set by an Allen key if someone set the velocity up very very high the gun will shoot much faster hurt much more but it will lose air much faster
One barrel
A sub-machine gun fires pistol cartridges. A machine gun fires rifle rounds.
