Web22 Sep 2024 · A : projected cross-sectional area of the object in a direction perpendicular to the object’s motion. At terminal velocity, v is replaced by vT. The drag force becomes. F D … 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 zero acceleration.
