Some projectiles provide propulsion during flight by means of a rocket engine or jet engine. In military terminology, a rocket is unguided, while a missile is guided . Note the two meanings of "rocket" (weapon and engine): an ICBM is a guided missile with a rocket engine.
Most projectiles used by terrestrial animals are liquids. Among invertebrates there are a number of examples. Velvet worms can squirt out a slimy adhesive fluid from glands on the sides of their head, and use it to trap their prey. The spitting spiders Scytodes can spit a venomous sticky fluid that traps its victims and also poisons them. [1]
Ballistics (from Ancient Greek βάλλειν bállein 'to throw') is the science of dynamics that deals with the flight, behavior and effects of projectiles, especially bullets, unguided bombs, rockets, or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.
Projectiles launched in the direction of a U.S. airbase in a gas field in Syria's Deir al-Zor province did not hit the facility, two U.S. officials said on Tuesday. Earlier, a security source told ...

Cannon-launched guided projectiles (CLGP) are precision-guided munitions launched by howitzers, mortars, tank guns, and naval guns.Those projectile main propulsion system is the initial kinetic shoot, directed as much as possible toward the target.
North Korea has developed a gun known in the West as Koksan, with a range of 60 km using rocket-assisted projectiles. (And see Trajectory of a projectile .) Such cannons are distinguished from rockets , or ballistic missiles , which have their own rocket engines, which continue to accelerate the missile for a period after they have been launched.
Projectiles are described by a ballistic coefficient, or BC, which combines the air resistance of the bullet shape (the drag coefficient) and its sectional density (a function of mass and bullet diameter). The deceleration due to drag that a projectile with mass m, velocity v, and diameter d will experience is proportional to 1/BC, 1/m, v² and ...
