# Velocity

Velocity is a measure of how fast something moves in a particular direction.[1] In other words, a velocity is a speed with a direction. For instance, if an object moves east at 9 metres per second (9m/s), we would say that its velocity is 9 m/s to the east.

To calculate the velocity of an object, we divide its displacement (its change of position) by the time it took to change position.[1]

${\displaystyle {\text{velocity}}={\frac {\text{displacement}}{\text{time}}}}$

For example, if an object moves 20 meters (m) to the left in 1 seconds (s), its velocity (v) would be equal to:

${\displaystyle {\text{v}}={\frac {\text{20 m}}{\text{1 s}}}={\text{20 m/s to the left}}}$

A change in velocity is acceleration
