An object launched into motion whose subsequent trajectory is determined by external forces. The ideal elementary projectile motion model retains uniform gravity and neglects air resistance.

A projectile is an object that is thrown, launched, or otherwise propelled into motion, often through the air, and continues to move due to its initial velocity and the influence of forces such as gravity and air resistance. Projectiles can come in various forms and can include anything from a thrown ball, a missile, an arrow, or even a spacecraft.
