Projectile

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.[1][2] 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, stone released from catapult).[3][4]

In ballistics mathematical equations of motion are used to analyze projectile trajectories through launch, flight, and impact.
