A projectile is any object that is thrown, fired, or otherwise propelled into the air. It follows a curved path called a trajectory, influenced by forces such as gravity and air resistance. Common examples of projectiles include bullets, arrows, and baseballs. In physics, the study of projectiles is part of kinematics, which examines the motion of objects. The motion of a projectile can be analyzed using equations that consider its initial velocity, angle of launch, and the effects of gravity. Understanding projectiles is essential in fields like sports, engineering, and military applications.
