Ever wonder why skydivers eventually reach a maximum speed when falling, even though the force of gravity in a vacuum will cause an object to continually accelerate? A falling object will reach a constant speed when there is a restraining force, such as drag from the air. The force applied by gravity near to a massive body is mostly constant, but forces like air resistance increase the faster the falling object goes. If allowed to free fall for long enough, a falling object will reach a speed where the force of the drag will become equal the force of gravity, and the two will cancel each other out, causing the object to fall at that same speed in freefall. This is called terminal velocity.
