What is defined as the highest point in a projectile's trajectory?

The highest point in a projectile's trajectory is referred to as the maximum coordinate. This term is used in ballistics and physics to describe the apex of the projectile's path, where its vertical velocity is momentarily zero before it begins to descend. At this point, the projectile has reached its maximum altitude due to the effects of gravity acting against its upward motion.

Understanding this concept is essential in fire control and targeting, as it affects calculations regarding range, stability, and potential impact area. The maximum coordinate allows operators to predict the subsequent behavior of the projectile, ensuring accurate targeting and effective engagement.
