Speed
What is a Velocity? (v)
Definition
Velocity is a measure of how fast something moves and in what direction. In basic problems, it is often treated as speed, and the most common calculation is average velocity: distance divided by time. Velocity is typically measured in meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph).
