'''Muzzle velocity''' is the velocity of the projectile immediatly after leaving the barrel, and other than a few hypothetical situations, is the fastest the projectile will ever go. Muzzle velocity is typicaly measured by a cronograph, a device that measures the time it takes the projectile to travle between 2 sensors, although less accurate results can be gathered from a [[balistic pendulum]] or the quite inaccurate [[hang time]] test.

==Muzzle energy==

This is muzzle velocity's companion, and can be calculated as following:
1/2MassVelocity^2 , where mass is in kilograms, velocity is in meters/sec, and output is in joules.
For instance, a 100g potato going 150 meters/sec (a large [[combustion launcher|combustion]] is capable of this) would have a muzzle energy of:
1/2*.1*150^2=1125 J

1.5 juels is approximatly 1 foot pounds, the traditional imperial (US) unit of energy for firearms.

It should be noted that in the case of saboted projectiles being simulated with the [[GGDT]], the acctual muzzle energy is equal to GGDT muzzle energy * projectile mass/projectile mass+sabot mass.

The following is a table of misc, rim, and centirfire ammunition muzzle energies, for comparison.
