Trajectory calculations involve determining the path that an object follows as it moves through space. This path is influenced by various factors, including initial speed, angle of launch, and the effects of gravity. By applying the principles of physics, particularly Newton's laws of motion, one can predict where an object will land or how it will travel over time. These calculations are essential in fields such as aerospace engineering, ballistics, and even sports. For example, understanding the trajectory of a basketball can help players make better shots. Accurate trajectory predictions can improve performance and safety in many applications.
