At terminal velocity, what happens to the net force on the falling object?

Explanation:
When an object falls in air, gravity pulls down and air drag pushes up. The net force is the downward weight minus the upward drag (mg − D). As speed increases, drag grows until it equals the weight. At that point, the forces balance and the net force is zero, so there is no further acceleration and the velocity remains constant—the terminal velocity. So, the net force at terminal velocity is zero.
