The difference between speed and velocity is that velocity is speed with a direction vector associated with it. It's that direction vector that makes them different. Let's back up a bit and review. Speed is displacement (distance traveled) per unit time. Velocity is displacement (distance traveled) per unit time in a given direction. The "directionallity" associated with velocity makes it a vector quantity, while speed is a scalar quantity.
