For a falling body near the surface of the Earth (explicitly including air drag), all of the following change with time except A) the acceleration of the body. B) the velocity of the body. C) the position of the body. D) the terminal speed of the body.

Question

Quizplus · Accepted Answer

The terminal speed of a body falling through a fluid (like air) is the maximum speed it will reach, where the force of gravity is balanced by the drag force. This speed does not change with time once it is reached, unlike acceleration, velocity, and position, which all vary over the course of the fall.
