"Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object. Since the net force on the object is zero, the object has … See more Based on air resistance, for example, the terminal speed of a skydiver in a belly-to-earth (i.e., face down) free fall position is about 55 m/s (180 ft/s).

WebDec 21, 2024 · What do you mean by terminal velocity? The steady speed at which an object free falls is known as the terminal velocity. As an object falls, its speed increases up to a point where the gravitational pull and drag force are equal. At this point, the velocity of the object becomes the terminal velocity, and the acceleration becomes zero. Webv (t) = v* t * (1 - exp [-bt/m]). In this case, the particle asymptotically approaches terminal velocity as time goes to infinity. So it never technically reaches terminal velocity. For the …
