Difference between revisions of "Velocity"

Velocity is very similar to speed but it includes the direction an object is moving.

Velocity is a vector quantity describing the speed and direction of a moving object.

Velocity is a scalar because it has magnitude and direction.

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.

Velocity = (Displacement) / (time)

\(v = \frac{x}{t}\)

Where\[v\] = Velocity of the object.

\(x\) = The displacement between the starting point and end point of a journey.

\(t\) = The time taken between the two points.

+: [[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).

+: The [[velocity]] of an [[object]] can change while the [[speed]] remains constant.
