Velocity

Velocity is the speed of a projectile fired from a weapon. It shouldn't be confused with use time, which is the speed of which an item can be used. For example, the fire rate of the Megashark would be its use time, while the speed of the bullets it fires, as they are fired, would be the velocity.

Different weapons can fire at higher or lower velocities in and of themselves. The type of ammunition you use can also affect the velocity. To top it all off, modifiers can increase or decrease your weapon's velocity as well. Velocity can be useful for the fact that you don't have to "lead" shots as much to hit a moving target. Weapons that use arrows essentially fire at lower velocities while bullet firing weapons fire at higher velocities.
