<onlyinclude>'''Velocity''' is the measurement of [[speed]] included with a direction.</onlyinclude> Both speed and direction are measured relative to some fixed object (in most cases, our planet earth). The numerical value of speed can be represented as a negative, which would indicate the opposite direction as indicated.

==Equation==
Velocity can be calculated from by the following expression:

<m>\vec{v} = \frac{\Delta x}{\Delta t}</m>

The arrow above the velocity variable v indicates that it is a vector variable, and has some direction.

==Velocity unit converter==
Please see below to convert among various units for velocity:

==Examples==
The train was moving at 50 km/h West.
*50km/h represents the speed
*West indicates the direction.

The Frisbee was thrown with a horizontal velocity of 10m/s
*10 m/s represents the speed
*the direction is horizontal, meaning the speed measurement is not accounting for the speed the Frisbee is falling

After the accident, the car was traveling at a velocity of -2 km/h
*The speed of the vehicle is 2km/h
*The direction would be the opposite direction which the vehicle is facing (intuitive deduction)

Hyperphysics has a more detailed discussion of [http://hyperphysics.phy-astr.gsu.edu/hbase/vel2.html velocity].
