A ballistic trajectory refers to the path that an object follows when it is launched into the air and moves under the influence of gravity and air resistance. This type of motion is typically observed in projectiles, such as bullets, rockets, or artillery shells, which are propelled forward and then follow a curved path before landing. The trajectory is influenced by several factors, including the object's initial speed, launch angle, and the effects of gravity and drag. Understanding ballistic trajectories is essential in fields like ballistics, aerospace engineering, and sports science, as it helps predict where a projectile will land and optimize its performance.
