Here's a breakdown:

* Speed: Measures how fast an object is moving, regardless of the direction. It's a scalar quantity, meaning it only has magnitude.

* Example: A car traveling at 60 miles per hour.

* Velocity: Measures both the speed and direction of an object's motion. It's a vector quantity, meaning it has both magnitude and direction.

* Example: A car traveling at 60 miles per hour eastward.

In simpler terms:

Imagine two cars:

* Car A is traveling at 50 mph. We know its speed.

* Car B is traveling at 50 mph north. We know its speed and direction, therefore its velocity.

Key Takeaway: Velocity provides a complete picture of an object's motion, while speed only tells us how fast it's going.
