muzzle velocity
Definition
Noun: - The speed of a bullet, shell, or other projectile at the instant it exits the muzzle (the open end) of a firearm's barrel.
Usage
This is a technical term used in ballistics, military science, and shooting sports. It is a specific measurement of a projectile's initial speed. - It is typically measured in feet per second (fps) or meters per second (m/s). - It is a key factor in determining a projectile's range, accuracy, and energy.
Examples
- The rifle's muzzle velocity is approximately 2,800 feet per second.
- Higher muzzle velocity generally results in a flatter trajectory over distance.
- Ballistic tests are conducted to measure the precise muzzle velocity of the new ammunition.
Advanced Usage
- Terminal ballistics vs. muzzle velocity: While muzzle velocity is the speed at the start, terminal ballistics studies the projectile's behavior upon impact.
- Factors affecting muzzle velocity: Barrel length, propellant type, and projectile weight all influence the final muzzle velocity.
Variants and Related Words
- Velocity (n): The speed of something in a given direction.
- Muzzle (n): The open end of a firearm's barrel from which the projectile exits.
- Muzzle energy (n): The kinetic energy of a projectile as it leaves the muzzle, calculated using its mass and muzzle velocity.
Synonyms
- Initial velocity (in the specific context of ballistics)
- Exit velocity
Related Phrases
- To achieve/have a muzzle velocity of...: Used to state the specific speed.
- The new round achieves a muzzle velocity of over 900 meters per second.
Noun
-
the velocity of a projectile as it leaves the muzzle of a gun
