Speed and Velocity. (n.d.). Ducksters.

Although speed and velocity are often used interchangeably in everyday life, they represent different quantities in physics. Speed is a measurement of how fast an object moves relative to a reference point. It does not have a direction and is considered a magnitude or scalar quantity. Speed is the magnitude of velocity. Velocity is the speed of an object plus its direction. Speed is called a scalar quantity and velocity is a vector quantity. To continue reading, follow the link above.
