Physics Form 4: Chapter 2 - Force Acting on a Skydiver

When an object falls, it accelerates. As its speed increases, the air resistance increases.
Eventually, the force from the air resistance will equal the force from the weight of the object.

At that point, the speed will remain constant: the object has reached its "terminal velocity" and can't fall any faster.
