Terminal velocity is achieved when:
A)you enter the freeway from the on-ramp.
B)Nolan Ryan's fastball impacts the catcher's mitt.
C)gravity is equalized by spinning.
D)there is a balance between the falling body and the drag of atmospheric molecules.

Question

Quizplus · Accepted Answer

Terminal velocity is the maximum velocity that a falling object reaches when the force of air resistance is equal to the force of gravity. At this point, the object stops accelerating and moves at a constant speed. Therefore, choice D is the correct answer as it describes the balance between the falling body and the drag of atmospheric molecules that characterizes terminal velocity.
