* Speed tells you how fast an object is moving. It's a scalar quantity, meaning it only has magnitude (e.g., 50 miles per hour).
* Direction tells you which way an object is moving. It's a vector quantity, meaning it has both magnitude and direction (e.g., north, 30 degrees east of north).
Therefore, velocity combines both speed and direction. For example, "50 miles per hour north" is a velocity.
Here's a simple analogy:
* Speed is like how fast you're driving your car.
* Direction is like which way you're driving.
* Velocity is like saying "I'm driving 50 miles per hour north."
