===About Terminal Velocity===

'''Terminal velocity''' depends on:

*The shape of an [[object]] - The more [[streamline]]d an [[object]] the greater the '''terminal velocity''' because they experience less [[Air Resistance|air resistance]] at a given [[speed]].

: '''Terminal velocity''' is the maximum [[velocity]] an [[object]] will reach when falling due to [[gravity]].
