Velocity - GCSE Maths Definition

Velocity is a measure of how fast something is moving in a specific direction. It is similar to speed, but while speed only tells us how fast something is going, velocity also tells us the direction it is going in. For example, if a car is travelling north at 60 miles per hour, its velocity is 60 mph north. In mathematics, velocity is often represented by a vector, which is a quantity that has both a size (magnitude - so the magnitude of velocity is speed) and a direction.
