Expression of terminal velocity
WebAug 11, 2024 · In the vertical plane, the only forces acting on the ball are the forces of weight and drag. There is a characteristic velocity which appears in many of the equations that is called the terminal velocity because it is the constant velocity that the object sustains during a coasting descent. Terminal velocity is noted by the symbol Vt. WebSep 12, 2024 · Example \(\PageIndex{1}\): Terminal Velocity of a Skydiver.
