		+	==Key Stage 4==
		+	===Meaning===
		+	[[Velocity]] is a [[vector]] quantity describing the [[speed]] and direction of a moving [[object]].
		+
		+	===About Velocity===
		+	: [[Velocity]] is a [[scalar]] because it has [[magnitude]] and direction.
		+	: The [[SI Unit]] for the [[magnitude]] of [[velocity]] is [[Metres per Second\|metres per second]] (m/s).
		+	: [[Velocity]] is different from its [[scalar]] counterpart '[[speed]]' because [[speed]] does not include the direction of travel.
		+	: The [[velocity]] of an [[object]] can change while the [[speed]] remains constant.
