For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
This schlieren image of a bullet travelling in free-flight demonstrates the air-pressure dynamics surrounding the bullet. External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying ...

A photo of a Smith & Wesson revolver firing, taken with an ultra high speed air-gap flash. Using this sub-microsecond flash, the bullet can be imaged without motion blur. Ballistics is often broken down into the following four categories: [23] Internal ballistics the study of the processes originally accelerating projectiles
Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]
Bullet trace can often easily be seen in humid weather, but also on cool and sunny days. There are several possible explanations of the phenomenon. The main cause is probably contrails which appear around the bullet due to pressure changes as the bullet travels through the air, thereby causing a short change in the light refraction of the air ...
"It was crazy fast.” And crazy to behold. The wind they felt came through holes the tornado made in her roof as it moved through Palm Beach Gardens' newest community at 140 mph.
