In this research article, we have successfully demonstrated an interesting characteristic of parabolic motion when the launch angle is at a critical value. Specifically, we have discovered an unexpected property associated with the distance between the launched object and the launcher. This property exhibits both a maximum and a minimum distance. We will illustrate that this phenomenon occurs only when the launch angle exceeds a certain threshold, specifically when . It is essential to highlight that our investigation of the launch scenario assumes a ground-level launch and does not account for the effects of air resistance. To emphasize the angular variable, we used dimensionless coordinates in our analysis. Critical launch angle is a key parameter determining the optimal angle for maximizing range and accuracy in projectile trajectories. This study offers a refined method to optimize trajectories for maximum efficiency and precision across various applications, enhancing performance and control. It can be used in various fields, such as sports and civil engineering.
