Here's why:
* Magnitude: This tells you how fast the object is moving. It's the numerical value of the velocity, usually measured in units like meters per second (m/s) or kilometers per hour (km/h).
* Direction: This tells you the direction in which the object is moving. It could be north, south, east, west, or any combination of these directions.
Example:
* Saying a car is traveling at 60 km/h is only describing its speed (magnitude).
* To describe its velocity, you would need to say something like, "The car is traveling at 60 km/h eastward."
Velocity is a vector quantity, meaning it has both magnitude and direction. Speed is a scalar quantity, meaning it only has magnitude.
