Here's why:

* Terminal velocity is the constant speed that a freely falling object eventually reaches when the force of air resistance equals the force of gravity.

* At this point, the object stops accelerating and falls at a steady rate.

It's important to note that:

* Terminal velocity is not a fixed value. It depends on factors like the object's shape, mass, and the density of the air.

* Air resistance is crucial. Without it, objects would continue to accelerate indefinitely as they fall.
