The rate of descent during a freefall skydive is primarily determined by the interaction between gravity and air resistance. After exiting the aircraft, the human body accelerates due to gravity’s pull. As velocity increases, the opposing force of air resistance, or drag, also intensifies. This drag acts against the downward motion, slowing the acceleration until a relatively constant speed is achieved.
Understanding the dynamics of descent is paramount for safety and control during the activity. Knowledge of these principles allows skydivers to manipulate their body position to adjust their fall rate. This is crucial for coordinating with other jumpers, executing maneuvers, and deploying the parachute at the correct altitude. Historically, advancements in skydiving techniques and equipment have been driven by a deeper comprehension of the physics governing freefall, leading to increased safety and the development of more sophisticated aerial skills.
