* Speed tells you how fast something is moving. It's a scalar quantity, meaning it only has magnitude (a numerical value). For example, a car traveling at 60 mph has a speed of 60 mph.

* Velocity tells you how fast something is moving *and* in what direction. It's a vector quantity, meaning it has both magnitude and direction. For example, a car traveling at 60 mph east has a velocity of 60 mph east.

Here's an analogy:

Imagine you're driving a car.

* Speed is like the speedometer reading – it tells you how fast you're going.

* Velocity is like the speedometer reading *plus* the direction you're facing.

In summary:

* Speed: How fast something is moving.

* Velocity: How fast something is moving and in what direction.
