Projectiles are objects that are thrown, fired, or otherwise propelled into the air. They can include items like bullets, arrows, and missiles. The motion of a projectile is influenced by forces such as gravity and air resistance, which affect its trajectory and speed. In physics, projectiles follow a curved path known as a parabola when launched at an angle. This motion can be analyzed using equations of motion, allowing scientists and engineers to predict where a projectile will land. Understanding projectiles is essential in fields like ballistics and sports science.
