Some do, some don't. The bullet from a .45ACP is subsonic. There are a number of planes that fly at supersonic speeds.
fast
because the atoms in solid are compact it helps sound to travel fast

Linght can travel very fast, because it has both wave and particle properties and it moves in stright line.
Nothing, they are two names for the same round.
.45 auto and .45ACP are the same round.
Approximately 1760 feet per second
because it is closer to the sun it has less to travel it is so fast because it is close to the sun and has less distance to travel

The glock 21 fires the .45 automatic colt pistol (.45acp, or .45 auto) round.
Some do, some don't. The bullet from a .45ACP is subsonic. There are a number of planes that fly at supersonic speeds.
The .50 BMG round travels at about 2,800 feet per second, or about 1,900 miles per hour.
Both can refer to 45ACP. 45 alone can also refer to 45 Colt
FPS is the measurement of speed in feet per second. Depending on what kind of bullet you are talking about, bullets can travel as fast as 4400 fps. Here are a few examples: 9mm-about 1050 fps. .45ACP-about 900 fps. 5.56mm-about 2700-3300 fps. .50bmg-about 2900 fps.
The .45 GAP was developed by an engineer with CCI/Speer, commissioned by Glock, to be a smaller round with the same power as a .45ACP. This was achieved essentially with powder selection. The .45 GAP has the same diameter as the .45 ACP but the case is shorter, it uses small pistol primers, and is designed for higher standard pressure to make it on par with the terminal velocity of the .45ACP round. To compensate for this increase in pressure the round has a stronger case head to prevent case head blowouts. The .45 GAP stands for "Glock Automatic Pistol" and is the first cartridge associated exclusively with Glock. The .45 GAP and the .45ACP are completely different rounds that are not interchangeable, although they perform similarly.
