They are made of a variety of materials, such as copper, lead, steel, polymer, rubber and even wax; and are made in various shapes and constructions (depending on the intended applications), including

thumb| A projectile being fired from an artillery piece A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow, a ball from a cannon, stone released from catapult).

thumb|150px|Feather fletching – these are shield cut with barred red hen feathers and a solid white cock. Fletching is the fin-shaped aerodynamic stabilization device attached on arrows, crossbow bolts, darts, and javelins, typically made from light semi-flexible materials such as feathers or bark. Each piece of such a device is a fletch, also known as a flight or feather. A fletcher is a person who attaches fletchings to the shaft of arrows. Fletchers were traditionally associated with the Worshipful Company of Fletchers, a guild in the City of London.
