hypervelocity
Faster than bullets
Hypervelocity describes speeds far exceeding what's typical for a given context—usually above 3 kilometers per second in physics and engineering.
At hypervelocity, impacts behave differently: objects don't just collide but vaporize or crater.
The term appears in discussions of meteorites, space debris, and military projectiles: hypervelocity impact testing, a hypervelocity railgun.
