What term describes an object projected by an applied force, commonly related to artillery rounds?

The term that describes an object projected by an applied force, especially in the context of artillery, is "projectile." This refers to any object that is thrown or propelled, often with the intent of impacting a target. In artillery, a projectile would typically refer to the projectile component of a round, which is ejected from the weapon due to the explosive forces generated by the propellant.

While "missile" is often used to describe a guided projectile, it typically implies that the object has an on-board guidance system and is meant for longer-range targeting. A "shell" usually refers to a type of projectile specifically designed for use in artillery, but it may not be a general term for any object that is propelled. "Round" refers more broadly to a complete unit of ammunition that includes the projectile, casing, and propellant, rather than describing the projectile itself.

Thus, the term "projectile" is the most accurate in defining an object that is projected by an applied force in the context of artillery rounds.
