A projectile is any object that is thrown, launched, or propelled into the air. It follows a curved path called a trajectory due to the influence of gravity and air resistance. Common examples of projectiles include arrows, bullets, and baseballs. In physics, the study of projectiles is important for understanding motion and forces. The motion of a projectile can be analyzed using equations that consider its initial speed, angle of launch, and the effects of gravity. This knowledge is applied in various fields, including sports, engineering, and military applications.
