Photo by R. A bullet firing from a handgun looks almost like a rocket launch—and works in very much the same way. Wound Ballistics: You can clearly see the heat of the explosive charge exploding from the front and the blast simultaneously shooting out from the rear.
Reid Jr. Dorling Kindersley, 2006. Before the invention of gunpowder, the first chemical explosive, people had to fight their enemies hand-to-hand on the battlefield with crude weapons like swords and spears.
Wiley, 2011. Some bullets go faster, some slower, but Chuck's table gives a good indication of average speeds.
A fascinating guide to how and why different types of bullets do different amounts of damage to a target. How the army is developing lead-free bullets to reduce environmental impacts. Once you have the time, you can figure out how far the bullet travels horizontally.
We call this idea gyroscopic inertia or stability. At the back, the primer or percussion cap is like the fuse of a firework: You calculate how long a bullet is in the air by finding its vertical velocity.

For that reason, it turns out they're slowed down much less by air resistance, so their actual range is more like a quarter to a half of their theoretical range. But it works pretty much the same way as a handgun bullet the size of your pinkie.
For high-speed projectiles such as bullets, drag air resistance increases as the square of the velocity. For younger readers Ready the Cannons by William Gurstelle.
