Unformatted text preview: called terminal velocity v t . When the object is moving with its terminal velocity v t the net force on it must be zero (no change in velocity means no acceleration). This occurs when D = mg, and the terminal velocity v t has to satisfy the following relation: and v t is calculated to be The equation for v t shows that the terminal velocity of an object increases with a decreasing effective area. The terminal velocity of an object is the final velocity it obtains during free fall. The object will obtain this velocity independent of whether its initial velocity is larger or smaller than the terminal velocity (see Figure 6.11)....
