5 ~1 Raindrop (4mm) ~9 ~20 Practical Applications and Examples This physical phenomenon is not merely a theoretical exercise; it has profound implications in various fields. This is why Felix Baumgartner's supersonic freefall from the edge of space, where air was extremely thin, could reach speeds exceeding the speed of sound, a velocity unattainable at sea level.
How Atmospheric Density and Altitude Affect Terminal Velocity
Terminal velocity represents the constant speed an object achieves when the force of gravity pulling it downward equals the drag force pushing upward, resulting in zero net acceleration. A streamlined body, like an arrow or a skydiver in a head-down position, cuts through the air efficiently, presenting a lower drag coefficient and achieving a higher terminal velocity.
Understanding this concept requires examining the intricate relationship between gravitational force, air resistance, and the physical properties of the falling object. As an object accelerates from rest, air resistance, or drag, increases proportionally to the square of its velocity.
How Atmospheric Density and Altitude Affect Terminal Velocity
Object Approximate Terminal Velocity (m/s) Approximate Terminal Velocity (mph) Human (spread position) 50-60 112-134 Human (head-down) 240-300 540-670 Feather ~0. Atmospheric Density and Altitude Effects Limitations and Real-World Considerations In a perfect vacuum, the concept of terminal velocity would not exist, as there would be no medium to create the opposing drag force, allowing an object to accelerate indefinitely under gravity.
