Speed is a scalar quantity and velocity is a vector quantity.
– **Speed** is the magnitude of how fast an object is moving. It only has magnitude and no direction. Quantities with magnitude only are called scalar quantities.
– **Velocity** is the rate of change of displacement. It has both magnitude (speed) and direction. Quantities with both magnitude and direction are called vector quantities.
For example, saying a car is travelling at “50 km/h” describes its speed (a scalar). Saying a car is travelling at “50 km/h North” describes its velocity (a vector).
