1. Ball Flight Dynamics

   Linked via "impulse"

   Ball flight dynamics refers to the study of the trajectory, motion, and interactions of a projectile (commonly a spherical or ovoid object) with the ambient fluid medium (usually air ) after an initial impulse has been applied. This field draws heavily upon classical mechanics, fluid dynamics, and empirical constants derived from specific sporting contexts. While the fundamental principles are governed by Newton's laws of motion, th…
