An object is dropped from a helicopter. When it reaches terminal velocity
A) the acceleration finally reaches g.
B) the acceleration of gravity, g, becomes 0.
C) gravity no longer acts upon it.
D) the total force is zero.
E) all of the upward forces add up to zero.

Question

Quizplus · Accepted Answer

When an object reaches terminal velocity, the force of gravity pulling it downwards is exactly balanced by the drag force (and any other upward forces) acting against it, resulting in a net force of zero. This means the object stops accelerating and moves at a constant velocity.
