Created page with "==Key Stage 4== ===Meaning=== '''Terminal velocity''' is the velocity a falling object reaches when the forces of drag and weight on that object are ..."

New page

==Key Stage 4==
===Meaning===
'''Terminal velocity''' is the [[velocity]] a falling [[object]] reaches when the [[force]]s of [[drag]] and [[weight]] on that [[object]] are [[Balanced Forces|balanced]].

===About Terminal Velocity===
: '''Terminal velocity''' depends on the [[density]] and shape of an [[object]].

 ===About Terminal Velocity===
 '''Terminal velocity''' depends on:
-*The [[density]] of an [[object]] - The more [[dense]] an [[object]] the greater the '''terminal velocity''' because larger [[object]]s will experience greater [[Air Resistance|air resistance]] at a given [[speed]].
+*The [[density]] of an [[object]] - The more [[dense]] an [[object]] the greater the '''terminal velocity''' because larger [[object]]s (of the same weight) will experience greater [[Air Resistance|air resistance]] at a given [[speed]].
 *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]].
