Explanation:

Objects in free fall have an acceleration due to gravity of approximately 9.8 m/s2. However, air resistance, a force that opposes the motion of an object through the air, also acts on the object. As an object falls, the air resistance increases until it reaches a point where it equals the force of gravity. At this point, the net force on the object is zero, and the object stops accelerating. This velocity is called the terminal velocity.
