Which term describes the midpoint in a ballistic trajectory?

• A. Maximum range
• B. Apex
• C. Center of gravity
• D. Impact point

Answer: (B)

The term that describes the midpoint in a ballistic trajectory is apex. The apex refers to the highest point in the trajectory of a projectile, where it reaches its maximum altitude before beginning to descend towards its impact point. At this point, the vertical velocity of the projectile is zero, and the forces acting on it due to gravity are beginning to pull it downwards. Understanding the significance of the apex is crucial in fire control as it determines the optimal point during the projectile's flight for assessing the effects of gravity and air resistance. This knowledge aids in predicting where the projectile will land and in making necessary adjustments for accurate targeting. The other terms do not accurately describe the midpoint in the trajectory. Maximum range refers to the furthest horizontal distance a projectile can travel; center of gravity relates to the point in an object where its mass is evenly distributed; and impact point is the location where the projectile eventually lands, all of which are distinct from the apex of the trajectory.
